Fan Pulley Alignment

Align as follows:

1. Loosen setscrews on pulleys.

2. Align pulleys visually and tighten setscrews on fan pulley to

lock it in place.

3. Use the methods shown in Fig. 25 to check proper pulley

alignment.

4. If pulleys are not in correct alignment, loosen the motor hold

down bolts and slide the motor axially until the pulleys are

aligned.

5. Tighten motor holddown bolts.

Fig. 25 — Fan Pulley Adjustments

Pulley and Drive Adjustment

To obtain desired fan speed, refer to the fan motor, drive data

and performance data in Tables 16-4 0

and adjust fan motor

pulley as follows:

1. Remove belt from fan motor pulley after loosening motor

from motor base.

2. Loosen setscrew in moveable flange of pulley. Screw move

able flange toward fixed flange to increase the fan speed and

away from fixed flange to reduce speed. Before tightening

setscrew, make certain that setscrew is over nearest flat sur

face of pulley hub. (See Fig. 25.)

Condensate Drains

Keep condensate drains free of dirt and foreign matter.

Return-Air Filters

Refer to Replacing Filters section on page 38 for filter

accessibility and removal. Replace with clean filters of the

sizes listed in Tables 1-6.

Coil Removal

Remove unit panels and corner posts as required. Disconnect

coil connections and remove fastening screws. Remove coil

through end or side sections of unit.

Cleaning Cooling Coil

Remove return-air filters. Remove any heavy dirt that may

have accumulated on underside of coil. Coil can be cleaned

more easily with a stiff brush, vacuum cleaner, or compressed

air when coil is dry. If coil is wet or if water is to be used for

cleaning, guard against splashing water on electrical compo

nents or damaging surrounding area. Clean coil baffles as ap

plicable and check for tight fit to be sure air does not bypass

coil.

Cleaning Insulation

The insulation contains an immobilized antimicrobial agent

that helps prevent the growth of bacteria and fungi. Clean the

inner surface of the insulation according to the separate main

tenance instructions shipped with the unit.

CAUTION

UNIT OPERATION HAZARD

Failure to follow this caution could cause equipment damage.

Increasing fan speed produces a greater load on motor.

Do not exceed rated capacity of motor.
