Blower Operation and Adjustments

Units are equipped with belt drive blowers; available

drive varies by model.

IMPORTANT

Three phase scroll compressors must be phased

sequentially for correct compressor and blower

rotation. Follow “COOLING START-UP” section of

installation instructions to ensure proper compres

sor and blower operation.

A - Blower Operation

Initiate blower demand at thermostat according to

instructions provided with thermostat. Unit will cycle on

thermostat demand. The following steps apply to

applications using a typical electro-mechanical

thermostat.

1- Set thermostat or temperature control device fan

switch to AUTO or ON. With fan switch in ON position,

blower will operate continuously. With fan switch in

AUTO position, the blower will cycle with demand.

2- Blower and entire unit will be off when thermostat or

temperature control device system switch is in OFF

position.

B - Determining Unit CFM

1- The following measurements must be made with air

filters in place.

2- With all access panels in place, measure static

pressure external to unit (from supply to return).

Blower performance data is based on static pressure

readings taken in locations shown in figure 9.

Note - Static pressure readings can vary if not taken

where shown.

3- Measure the indoor blower wheel RPM.

4- Referring to pages 9-14, use static pressure and

RPM readings to determine unit CFM. Use

option/accessory air resistance table on page 15

when installing units with any of the options or

accessories listed. Refer to table 3 for minimum

airflow when electric heat is installed.

5- The blower RPM can be adjusted at the motor pulley.

Loosen Allen screw and turn adjustable pulley

clockwise to increase CFM. Turn counterclockwise to

decrease CFM. See figure 10. Do not exceed

minimum and maximum number of pulley turns as

shown in table 1.

TABLE 1

MINIMUM AND MAXIMUM PULLEY ADJUSTMENT

Belt Min. Turns Open Maxi. Turns Open

2- To increase belt tension -

Slide blower motor downward to tighten the belt. This

increases the distance between the blower motor and

the blower housing.

To loosen belt tension -

Slide blower motor upward to loosen the belt. This

decreases the distance between the blower motor

and the blower housing.

3- Tighten four bolts securing motor base to the

mounting frame.

D - Check Belt Tension

Overtensioning belts shortens belt and bearing life.

Check belt tension as follows:

1- Measure span length X. See figure 12.

2- Apply perpendicular force to center of span (X) with

enough pressure to deflect belt 1/64” for every inch

of span length or 1.5mm per 100mm of span length.

Example: Deflection distance of a 40” span would be

40/64” or 5/8”.

Example: Deflection distance of a 400mm span

would be 6mm.

3- Measure belt deflection force. For a used belt, the

deflection force should be 5 lbs. (35kPa). A new belt

deflection force should be 7 lbs. (48kPa).

A force below these values indicates an

undertensioned belt. A force above these values

indicates an overtensioned belt.
