Operation/Screens/Cleaning Casement and awning windows

1.1

Casement and awning windowsoperation

pella® impervia® casement windows feature a convenient locking system — a single, easy-to-reach sash lock handle

operates both window locks. to open the window, just lift the sash lock to unlock the window, then pull out the

fold-away handle and rotate it. Be sure to unlock the window before you try to open it — otherwise, you’ll risk

damaging the operating mechanism. to close the window, reverse the steps. Be sure to lock the sash whenever

the window is closed; it will ensure the window is properly sealed.

awning windows are similar to casement windows turned on their sides. Awning windows are designed to be opened to a 45° angle or less.

If you prefer a different look, casement and awning handles and lock levers can be replaced with hardware in a different color/finish. See the

Pella Window and Door Showroom nearest you for details.

Flat screensFull standard fiberglass

removing the screen from the interior of the house/building requires two hands. Pivot the screen latch clips

out of the grooves on the side of the window frame. While holding the screen latches securely, carefully bring

the screen into the house/building.

installing the screen from the interior of the house/building requires two hands. Make sure the screen handle

and screen latch clips are facing the interior, and then position the screen in the window frame. Pivot the screen

latch clips into the grooves on the sides of the window frame to hold the screen in place.

warning: use caution when children or pets are around open windows and patio doors. screens are not designed to retain children or pets.

Caution: to help avoid scratching the fold-away handle or window frame, make sure the screen latches are fully retracted when removing or installing screens.

Cleaning

Cleaning the glassTo wash the glass:

1. Use a premixed vinegar-based cleaning solution (or make your own with one part white vinegar to 10 parts water), and apply to a soft,

clean, lint-free microfiber cloth or paper towel. Or you may use an ammonia-free glass cleaner such as Windex® (clear liquid) or Sparkle®

(purple liquid). Feel free to be generous with the amount of cleaner you apply, but avoid getting any cleaning solution on the fiberglass

frames as it may discolor the finish.

2. Rub from several different directions.

3. Rinse with clear water if streaks remain after cleaning.

Caution: do not use glass cleaners that are ammonia- or alcohol-based. they may leave streaks or produce a film that attracts moisture or dust.

1.2

spot-cleaning stubborn materials on all glassTo remove any markings from grease, oil, tape adhesive, crayons or paint, or marks from plastics that may have come in contact with the glass:

1. Apply a small amount of a nonabrasive cleaner such as Bar Keepers Friend® (SerVaas Laboratories) to a clean, wet cloth — or apply a solvent

such as acetone or mineral spirits to a clean, dry, lint-free microfiber cloth or paper towel.

2. Rub on the areas of glass that need spot-cleaning. Avoid getting any cleansers or solvents on the fiberglass frames

as they may discolor the finish.

3. Wipe clean using a clean, dry, lint-free microfiber cloth or paper towel.

4. Then clean the glass as instructed on page 1.1.

Caution: do not use a razor blade to scrape off stubborn materials — doing so may leave permanent marks on the glass or scratches that could cause glass breakage. Contact the pella window and door showroom nearest you for special cleaning instructions.

spot-cleaning marks on a sundefense™ dual low-e room-facing glass surfaceOccasionally, a mark may appear on the interior of Dual Low-E glass due to metal coming in contact with the surface.

Most often, this is not a scratch and can be removed using the following instructions:

1. Apply undiluted white vinegar to a soft, clean, lint-free microfiber cloth or paper towel.

2. Rub the marked area from several different directions.

3. If the mark still remains on the room-facing Low-E glass surface, apply a small amount of Bar Keepers Friend® or Cerama Bryte® Ceramic

Cooktop Cleaner to a soft, clean, lint-free microfiber cloth or paper towel. Avoid getting any cleansers or solvents on the fiberglass frame

as they may discolor the finish.

4. Rub the marked area again from several different directions until it disappears.

5. Then clean normally as instructed on page 1.1 “Cleaning the glass.”

NOTE: Some marks may require repeating this process.

Cleaning egress windowsSome windows have optional emergency-exit (egress) hardware identified by red “Open” labels. These windows are designed to provide a

wider opening when fully opened. To wash casement egress windows:

1. Unlock the sash and crank the roto-operator to position the roto-operator shoe against the “Wash” label on the egress operator slide.

2. Push the bottom release levers outward to release the hinges.

3. Slide the edge of the sash toward the center of the window opening. The sill hinges will lock in place and position the sash for washing.

4. The release lever will automatically reset when the window is closed.

Cleaning flat screensFull standard fiberglass

To clean a flat fiberglass screen, either remove the screen (see page 1.1) and gently wash it with soap and water, or use the drapery brush

attachment on your vacuum cleaner.

Vivid View® high-transparency screens

To clean Vivid View screens, remove them from your windows and hose them off with water.

note: the ultrafine screen material is more delicate than fiberglass or aluminum screens and should be handled with care.

warning: use caution when children or pets are around open windows and patio doors. screens are not designed to retain children or pets.

Caution: do not power-wash.

Cleaning the interior frame and sash material To remove any markings from grease, oil, tape adhesive, crayons or paint, or marks from plastics that may have come in contact with the

interior of your frame and sash material, clean the surface with warm, soapy water. For best results on stubborn stains, Pine-Sol® should be

applied with a clean, dry cloth or towel. Should you need it, touch-up paint is available at the Pella Window and Door Showroom nearest you.

warning: do not use abrasives. do not scrape or use tools that might damage the surface.

Cleaning the exterior frame and sash material Clean the surface with warm, soapy water. Stubborn stains and deposits may be removed with mineral spirits. Should you need it, touch-up paint

is available at the Pella Window and Door Showroom nearest you.

warning: do not use abrasives. do not scrape or use tools that might damage the surface. do not power-wash.

Cleaning the weatherstrip Frame weatherstrip and sash rainstrip should be wiped down with warm soapy water annually to ensure maximum window performance.

Cleaning the hinge slide The hinge slide at the sill (bottom) of casement windows and on the side of awning windows should be lubricated twice a year to remove dirt

and debris. The hinge slide should be lubricated with WD-40 penetrating oil or silicone dry film lubricant to ensure smooth operation.

Cleaning the hardware finish A soft cloth and mild cleaner may be used on all hardware finishes for Pella® windows.

note: oil-rubbed bronze window hardware is a living finish that will develop its own unique patina with use, care and handling.

2.2

Cleaning the exterior glass from the interiorYou can remove the venting sash of the sliding window for easy cleaning.

Unlock the window and slide to the fully opened position (1). Make sure that

the sash has cleared the anti-lift clip, which is a security feature that prevents

removal of sash when closed, located at the top of the frame (2). Lift the sash

up and out of the bottom track, then tilt in the bottom of the sash until it

clears the frame (3).

Caution: sash may be heavy.

Lay sash flat to wash the exterior glass on the vent panel. To wash the fixed panel from the interior of the

building, remove the screen and reach out to wash the exterior glass.

Caution: do not extend your body out of the window. if the entire glass of the fixed panel cannot be reached from the interior of the house/building, wash the fixed panel from the exterior of the house/building.

When reinstalling the sash, be sure to insert the top of the panel into the frame in the fully open position

so that you clear the anti-lift clips, then rotate the bottom into position. Close and lock the sash a few times to ensure proper operation.

For exterior glass-cleaning solution, follow the “Cleaning the glass” steps on page 2.1.

Cleaning the track and weep valve assembliesTo remove dirt or debris on the track of the window, unlock the window and •

slide the operating sash panel to the fully opened position (1). Make sure

that the sash has cleared the anti-lift clips located at the top of the frame (2).

With both hands, lift the sash up and out of the bottom track. Set the sash •

in a safe place until you are ready to reinstall (3).

Caution: sash may be heavy.

Locate the sill track in the bottom inside channel of the window. If you use a

vacuum cleaner with the brush attachment to clean out the debris in the track,

the sash will be easier to operate.

Insert a stiff-bladed putty knife between the interior of the frame and the sill •

track, and pry upward to start removal (4). Once started, grab the sill track and

lift upward to complete the removal of the track (5).

Vacuum out any debris and thoroughly clean the sill channel with warm, •

soapy water prior to reinstalling the sill track. Flush out the weep system by

slowly pouring a few quarts of rinse water into the sill channel (6). The water

should drain readily to the exterior (7).

Starting at one end and continuing along the entire length, push the •

sill track down to snap into place (8). Be sure that both the interior and

exterior sides of the sill track are snapped fully into place. Lightly tapping

a block of wood with a rubber mallet along the entire length will help

ensure that the sill track is in place. Reinstall the sash by inserting the top of

the sash up into the frame and down into the bottom. Close and lock the sash

a few times to ensure proper operation.

note: when reinstalling the sash, be sure to insert the panel into the frame in the fully open position so that you clear the anti-lift clips (2). Cleaning the weep valve assemblies with water must be completed when the temperature has been above freezing for at least 48 hours to ensure water does not freeze in the assembly.

Cleaning

Cleaning the glassTo wash the glass:

1. Use a premixed vinegar-based cleaning solution (or make your own with one part white vinegar to 10 parts water), and apply to a soft,

clean, lint-free microfiber cloth or paper towel. Or you may use an ammonia-free glass cleaner such as Windex® (clear liquid) or Sparkle®

(purple liquid). Feel free to be generous with the amount of cleaner you apply, but avoid getting any cleaning solution on the fiberglass

frames as it may discolor the finish.

2. Rub from several different directions.

3. Rinse with clear water if streaks remain after cleaning.

Caution: do not use glass cleaners that are ammonia- or alcohol-based. they may leave streaks or produce a film that attracts moisture or dust.

Pella® Impervia® Windows and Patio Doors

Pella recommends you inspect your windows and doors at least annually as part of a home checkup. Recommended maintenance can prolong

the life of your Pella Impervia windows and patio doors and will help ensure maximum warranty coverage. As needed, clean your windows

and patio doors, and recaulk around the perimeter to help maintain optimal performance. Also be sure to check for leaks regularly, improper

drainage above or around vents, and sprinkler systems that may subject your windows and doors to prolonged water exposure. With

recommended care, Pella Impervia windows and patio doors and Special Shape windows can reward you with many years of beauty and

performance.

exteriorAn annual checkup can help preserve and maintain the beauty of your Pella Impervia products for years to come.

Inspect the sealant/caulking on the exterior perimeter of your windows and patio doors at least once a year. The sealant/caulking helps create

a watertight seal between the window and door frames and the exterior siding (whether it is vinyl, cedar, aluminum, brick, etc.) or stucco.

It is extremely important that the sealant/caulking remains intact and in good condition at all times. Pay particular attention to the caulking at the

lower corners of windows and under joints between windows in combinations (a grouping of individual windows). The sealant material should

not be cracked, broken or missing — or it may cause premature failure of your Pella Impervia products or other parts of your home. Deterioration

that occurs as a result of improper or insufficient maintenance is not covered by the Pella Impervia Limited Lifetime Warranty.*

Pella Impervia windows and patio doors arrive prefinished. Check the paint, and if the surface is damaged, the exposed areas must be repaired

immediately to prevent further damage. Should you need it, touch-up paint is available at the Pella Window and Door Showroom nearest

you. If you need further assistance, contact your local Pella representative. Please note that if you do paint over the factory finish, Pella’s paint

warranty is voided.

interior finishAt least once per year, inspect the interior finish of your windows and/or doors to make certain that the finish is in good condition. UV rays

from the sun can break down the finish and compromise its protective features.

can clean it using a vacuum cleaner with the drapery brush attachment. do not use oily lubricants to clean the track; they attract dust and grime,

which will eventually restrict the door’s movement.

salt spray environments The seacoast environment is extremely hard on all sorts of products (automobiles, recreational vehicles, building products, etc.). Any product

used in a seacoast location will require more frequent inspection and maintenance to help it last as long as possible in this harsh environment.

Windows and doors are no different from other products in this respect.

If your home is in a coastal environment and is subjected to wind-driven salt spray or salt fog, use a mild detergent soap and water to clean

the exteriors, including operating hardware, at least quarterly — and more often if necessary — to prevent salt or other abrasive materials from

building up on the exterior surfaces.

Caution: do not power-wash.

preventing condensationunderstanding condensation.

Moisture is present in all homes, but when it becomes excessive, homeowners need to take an active role in protecting their investment.

Humidity and condensation.

Humidity is a measure of the amount of water vapor in the air.

Condensation is water that forms when warm, moist air hits a cooler surface. In homes, it might occur on surfaces such as windows, bathroom

walls and cold-water pipes.

When interior humidity levels are too high, in relation to cooler outdoor temperatures, condensation can form on the coldest surface in a room —

often the glass in a window or door. While windows and doors do not cause condensation, they may be one of the first places it shows up.

7.3

troubleshooting

what causes condensation?

Excess humidity is typically the cause of condensation. There are many sources for moisture in a home: showers, dishwashers, clothes washers

and dryers, house plants, humans and pets, among others. In newly built homes, additional moisture may escape from building materials such

as lumber, plaster and masonry for up to three heating seasons — even with proper airflow and temperature management.

older vs. newer homes.

Condensation may be less of an issue in older homes if conditions allow for more air exchange between indoors and out, often from around

aging, loose or poorly installed windows and doors. However, the tradeoff is higher energy bills. When replacement windows are properly

installed and the airflow around the window decreases, condensation may form on the glass of the new windows.

Newer homes, on the other hand, are more airtight and energy-efficient. Many have vapor barriers — plastic within the wall cavity blocking

moisture passage in either direction. With tighter-fitting doors and windows, vapor barriers and increased insulation, energy costs are lower, but

humidity levels must be monitored more closely.

No matter when your home was built, the key is to strike the right balance when it comes to humidity levels. Air that’s too dry can cause furniture

to dry out and crack, joints and studs to shrink and twist, and paint and plaster to crack. Excessive moisture in the home can cause paint to peel

and insulation to deteriorate, and condensation on windows and doors can damage sills and trim.

measuring and controlling humidity.

To determine how much humidity is present in your home, you can purchase a humidity

gauge from a hardware store or home center. Invest in a quality unit for greater potential

accuracy in assessing humidity levels, or consult an expert. Another way to monitor

the interior humidity level is to watch your windows. When interior condensation

begins to form, wipe it off. To reduce the humidity, open windows, run exhaust fans or

dehumidifiers, or minimize sources of moisture.

The University of Minnesota Laboratories provides a chart showing recommended relative

humidity levels for the home.

exterior condensation.

Exterior condensation on windows occurs primarily in the morning when days are warm and humid, but nights are cool. Typically, it clears as

the day warms. Exterior condensation can occur at any time, especially in warm, humid climates where interior temperatures are cooler than

outdoor conditions. Exterior condensation means that windows are doing their job properly. However, if you spot excessive condensation on

the inside of your windows, check your inside humidity — it may be a signal of potential problems if not addressed.
