Fig. 21 — Fan Pulley Adjustments

Belt Tension Adjustment

Shut off unit power supply. Lock out power supply and tag discon

-

nect  locations.  Loosen fan  motor  mounting  plate  bolts.  Do  not

loosen motor mounting bracket from unit. Adjust belt tensioning

bolts until proper belt tension is obtained.

Changing Fan Wheel 

 If a fan wheel should fail, it may be replaced as follows:

1. Remove belts from fan pulley.

2. Loosen locking collars on the fan bearings and set screws on

the fan wheels.

3. Remove the shaft through the access panel on either side of

the unit.

4. Remove the fan cut-off plate in the fan discharge.
5. Remove the fan wheel through the fan discharge opening.
6. Replace the wheel, and reverse Steps 1-4 above.

Fan Bearing Replacement

If a fan bearing fails, replace it as follows:

1. Remove belts from the fan pulley.

2. Support fan shaft.
3. Loosen locking collar on fan bearing.
4. Remove bearing from the shaft.
5. Install  new  bearing  onto  the  shaft,  and  reverse  Steps  1-3

above. 

Concentric Alignment

Shaft and wheels must be concentrically centered with the venturi

or air inlet of the fan housing (see Fig. 22).

Fig. 22 — Concentric Alignment

Shaft bearings are supports by bearing supports (Fig. 23). If shaft

and wheels are concentrically misaligned from shipping shock, it

is possible to re-bend the bearing support arms to the original posi

-

tions. Replace the bearing support if it has extensive damage.

Evaporator and Condenser Motor Starter Setting

(after Lockout/Tagout)

Motor starter is factory set. If starter is replaced in the field, use the

following procedure to set:

1. On the starter, adjust the Motor Overload to match the 

FLA

Rating

 of the installed motor by turning the Overload Set

-

point wheel to the appropriate value. See Fig. 24. Evaporator

and condenser motor FLA Ratings are listed in Table 21.

2. On the starter, turn the Motor Overload Reset wheel to 

M-O

(referred to as Manual Reset).

3. On  the  starter,  depress  the  Motor  Overload  Reset  wheel
