Unit Installation

Installation ConsiderationsFor proper installation and operation,

check each of the following beforemounting the units:

1. Allow adequate space for the unitinstallation and service clearances.

For servicing and routine

maintenance, provide access tothe unit through removable panels

in the ceiling.2. Before installing any unit make

sure proper preparation has been

made at each unit location forpiping and electrical connections.

3. If adding external accessories tothe unit, additional clearance must

be considered for the overall space

needed.4. Check the supporting structure

(ceiling) should be strong enoughto support unit weights. All units

must be mounted level to assure

proper drainage and operation.

5. Ducting connected to units shouldnot exceed the external staticpressure rating of the unit.

6. Condensate protection for the

chilled water valves and pipingmust be provided by installer

should be located under the valvesor else the valves and piping

should be throughly insulated.

Note: The general location of the Fan

Coil Unit is normally selected by thearchitect, contractor, and/or buyer.

For proper installation, the following

items must be considered.

Installation ProcedureTo proper installation procedure, TraneHFCC/HFCD Chilled Water Fan Coil

follow these steps:

Coil ConnectionsCoil connection for HFCC model is 5/8

inch, HFCD model is 3/4 inch coppertube. To complete piping connections,

attach the water pipe to the coil

connection at header. The water inlet

is on lower tube and the water outlet ison upper tube of the header. Coilconnection size and coil connection

locations are given on dimensional

data. For coil connection, as shown inFigure 1.

Connecting the unit with brazing

procedureTo braze the copper tube, use acoupling between the copper tube of

Fan Coil Unit and water pipe as

shown in Figure 2.

Note: Before brazing a copper tube toa solder coupling or a copper tube to

an expanded tube, do not forget tokeep them tight.

Condensate Drain Connections1/2 inch PVC pipe (or flexible pipe)

connection can be used as a drainline. Attach the drain line to the drain

connection with tape-sealant to

prevent leakage. To conveniently drainthe system, the drain piping must slant

downward, with a slope of at least

drain system. Avoid putting the end of

the drain pipe in water and the drainpipe should run straight down the wall

to a level where the run off will not

stain the wall.

Note: When the drain pipe is placed inthe room, should insulate the pipe with

foam polyethylene to avoid damage tothe ceiling or furniture.

MountingThe Trane model HFCC/HFCD unitsare designed to be suspended from

the ceiling on threaded rods furnished

by the installer. Holes are provided atthe top of the units, see dimensional

data for cutout dimensions andlocations.

1. Install the suspension rods or other

suspension devices that must beprovided by installer.

2. Put the upper W 3/8" nuts and W3/8" lock washers on suspension

rods to prevent unit from upward

tilting during unit operation or duct

Typical Installation.3. Hoist the unit into position. See

dimensional data for unit weights.

4. Put on the lower W 3/8" lockwashers and then 3/8" nuts to

secure the unit, as shown in

5. Level the unit casing to avoid poor

condensate drainage by adjusting

lower nuts up/down, and thentighten the upon nuts.

Caution: Level the unit by checking

on the unit casing. Do not use the coilor drain pan for leveling as they are

pitched to provide proper drainage.

Caution: Verify tha t the unit elec trica lpower is disconnected.

• Inspect all fields w iring connections.

All connection should be clean and

tight.

• Inspect unit ground connection.

G round must co mply with all

applica ble codes .

• Unit casing is level. Remove any

tools or debris found in or near

the unit.

• Inspect duct outlets . Ductwork

connections are completed and

outlets must be open andunrestricted.

• Coil connections are completed

and tight.

• Condensa te dra in pan connect ions

must be tight a nd drain

unrestricted.

• Inspect fan assembly to insure all

moving parts move freely.

• Inspect unit for proper filters,

se curely insta lled. All ca binet

panels must be secured.

Caution: Disc onnect electrica l pow er

sources and secure in disconnectedpos ition before servicing the unit.

Failure to do so may result in personal

injury or dea th from electrica l shoc k.

Coil VentingWhen w a ter is first introd uced into a

Regular MaintenanceBe sure to disconnect the power

before inspection or maintenance of

air conditioner.

1. Cleaning the air filter

Air flow is reduced and cooling

efficiency impaired if the filter is

clogged. Be sure to clean the filter

every two weeks during the coolingseason.

1.1 How to remove the air filters

- Loose screws located under

the filter in return air plenum

set.

- Remove air filter frame from

return air plenum set.

1.2 How to clean the air filter.

- Wash away dust from the air

filter with clean water or

vacuum it with an electric

vacuum cleaner.

Note: Once the air filter is washed,

dry it completely before returning it to

its original position.

After cleaning be sure to return it to its

original position.

Cautions - Do not wash the air filter in water

that is over 40ºC or it may shrink.

- Do not expose the air filter to fire. - Do not expose the air filter to direct

sunlight for a long time.

- Clean the air filter more frequently
