Fan Rotation

Correct fan rotation with respect to fan outlet is shown in

Fig. 24.

To reverse the direction of rotation of a 3-phase fan motor,

reverse any 2 of the power leads. Refer to the connection

diagram on the inside of motor terminal box cover for proper

reversing procedure of a single-phase motor.

Fig. 24 — Fan Rotation

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.

Fig. 25 — Fan Pulley Adjustments

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

holddown  bolts  and  slide  the  motor  axially  until  the

pulleys are aligned.

5. Tighten motor holddown bolts.

Pulley and Drive Adjustment

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

data and performance data in Tables 16-38 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

moveable 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 surface 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 37  for  filter

accessibility and removal. Replace with clean filters of the

sizes listed in Tables 1-4.

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  com

-

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

used for cleaning, guard against splashing water on electri

-

cal components or damaging surrounding area. Clean coil

baffles as applicable  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

maintenance 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.
