12.5.4. Ductwork 12.5.4.1. Attaching Horizontal Ductwork to Unit

All conditioned air ductwork should be insulated to minimize heating and cooling duct losses. Use a minimum of two (2) inches of insulation with a vapor barrier. The outside ductwork must be weatherproofed between the unit and the building. When attaching ductwork to a horizontal unit, provide a flexible watertight connection to prevent noise transmission from the unit to the ducts. The flexible connection must be indoors and made out of heavy canvas. Note: Do not draw the canvas taut between the solid ducts.


52

12.5.4.2. Attaching Downflow Ductwork to Roof Curb

Supply and return air flanges are provided on the roof curb for easy duct installation. All ductwork must be run and attached to the curb before the unit is set into place.

Follow these guidelines for ductwork construction:

Connections to the unit should be made with three-inch canvas connectors to minimize noise and vibration transmission.

Elbows with turning vanes or splitters are recommended to minimize air noise and resistance.

The first elbow in the ductwork leaving the unit should be no closer than two feet from the unit, to minimize noise and resistance.

12.6. Electrical Wiring Electrical Power It is important that proper electrical power be available for the unit. Voltage variation should remain within the limits stamped on the unit nameplate. Disconnect Switch Provide an approved weatherproof disconnect either on the side of the unit or within close proximity and within sight of the unit. Over Current Protection The branch circuit feeding the unit must be protected as shown on the unit rating plate. Power Wiring The power supply lines must be run in weather tight conduit to the disconnect and into the bottom of the unit control box. Provide strain relief for all conduits with suitable connectors. Provide flexible conduit supports whenever vibration transmission may cause a noise problem within the building structure. Be sure all connections are made tight. Control Wiring (Class II) Low voltage control wiring should not be run in conduit with power wiring unless Class 1 wire of proper voltage rating is used. Make connections as shown on the unit wiring diagram. Do not short thermostat wires since this will damage the control transformer. Important: Upon completion of wiring check all electrical connections, including factory wiring within the unit, make sure all connections are tight. Replace and secure all electrical box covers and access doors before leaving the unit or turning on the power to the unit.

Note

Knock down the control box access panel, first twist off screws and then up it, the control box access panel is getting out.

12.7. Start–Up Packaging and Components n Is the unit properly located and level with the proper clearance?

n Is the duct work correctly sized, run, taped, insulated , and weatherproofed with proper unit arrangement? See Ductwork Installation section.

n Is the wiring properly sized and run according to the unit wiring diagram?

n Are all the wiring connections, including those in the unit, tight?

n Has the unit been properly grounded and fused with the recommended fuse size? See Wiring Data.

n Have the air conditioning systems been checked at the service ports for charge and leak tested if necessary?

n Does the condenser fan and indoor blower turn free without rubbing, and are they tight on the shafts?

n Has the indoor blower speed been determined and the proper speed been set? See the Unit Wiring Diagram.

n Are all covers and access panels in place to prevent air loss and safety hazards?

Starting the Unit in the Cooling Mode Caution:

Before starting the system on the cooling cycle, turn the thermostat switch to OFF and close the unit disconnect switch. This procedure energizes the compressor crankcase heater, vaporizing any liquid refrigerant in the crankcase. This is a precaution against foaming at startup which could damage the compressor bearings.

Allow the heater to operate a minimum of eight (8) hours.

To start the unit in the cooling mode, set the thermostat system switch to COOL and move the thermostat COOL indicator to a setting below room temperature. The condenser (outdoor) fan motor compressor and evaporator (indoor) fan motor will operate automatically.

Voltage

With the compressor operating, check the line voltage at the unit. The voltage should be within the range shown on the unit nameplate.

If low voltage is encountered, check the size and length of the supply line from the main disconnect to the unit. The line may be undersized for the length of the run.

Cooling Shut Down

Place the system selector in the OFF position or reset thermostat at a setting above room temperature.

Do not de-energize the main power disconnect except when unit is to be serviced. Power is required to keep the heat pump compressor warm and boil off refrigerant in the compressor.

12.8. Maintenance Routine Maintenance by Owner You can do some of the periodic maintenance functions for your unit yourself; this includes cleaning the permanent air filters, cleaning the unit cabinet, cleaning the condenser coil, and conducting a general unit inspection on a regular basis

Cleaning the Air Filter 1. Dismantle the air filter.

● Twist of screws and up the plate that is gets out.

● Make the Clasp of air filter from horizontal to vertical.

● The air filter turns 30 degree to out.

Figure 9

2. Clean the air filter (Vacuum cleaner or pure water may be used to clean the air filter. If the dust accumulation is too heavy, please use soft brush and mild detergent to clean it and dry out in cool place).

Figure 10


55

● The air-in side should face up when using vacuum cleaner.

● The air-in side should face down when using water.

Caution: Do not dry out the air filter under direct sunshine or with fire.

3. Re-install the air filter

Condenser Coil

Unfiltered air circulates through the unit's condenser coil and can cause the coil's surface to become clogged with dust, dirt, etc. To clean the coil, vertically (i.e., with the fins) stroke the coil surface with a soft-bristled brush. Be sure to keep all vegetation away from the condenser coil area.

MAINTENANCE PERFORMED BY SERVICEMAN--COOLING SEASON

To keep your unit operating safely and efficiently, the manufacturer recommends that a qualified serviceman check the entire system at least once each year and any other time that you feel one is needed. Your serviceman should examine these areas of your unit:

● filters

● motors and drive system components

● economizer gaskets (for possible replacement)

● safety controls (for mechanical cleaning)

● electrical components and wiring (for possible replacement and connection tightness)

● condensate drain (for cleaning)

● unit duct connections (to see that they are physically sound and sealed to the unit casing)

● unit mounting support (for structural integrity)

● the unit (for obvious unit deterioration)

Caution

Do not operate the unit without the evaporator fan access panel in place. Reinstall the access panel after performing any maintenance procedures on the fan. Operating the unit without the access panel properly installed may result in severe personal injury or death.
