Motor Pulley Adjustment, Startup Inspection

INSTALLATION

MOTOR PULLEY ADJUSTMENT

NOTE: ALL DUCT CONNECTED COOLERS MUST BE ADJUSTED.

Long or small air ducts have excessive air resistance which decreases air output and motor amperage.You may compensate for this by adjusting the motor pulley. Use a clamp type ampmeter to check the motor amperage.

1.Check amperage at the white lead in the wiring box.

2.If the amperage is less than the motor nameplate amperage, loosen the pulley pitch adjustment screw, turn in the pulley 1/2 turn, tighten the screw and recheck the amperes. Repeat as necessary to bring the amperage to the nameplate rating.

3.If the amperage is too high, turn out the pulley as required.

4.Adjust the belt tension as required. (See page 13)

IMPORTANT

NOTE: When checking amperage with the ampmeter, all louvers must be in place in the cooler, otherwise incorrect setting of the drive pulley will occur.

STARTUP INSPECTION

Before starting the cooler, make sure all installations and adjustments are correct. Be sure that:

•Cooler is level and duct is sealed.

•Cabinet is securely fastened to the mount.

•Cooler is grounded. Electrical connections are secure.

•Blower wheel does not rub against housing.

•Water supply is turned on.

•Water line is connected securely and fittings and crossover tube grommets do not leak.

•Float is adjusted for proper water level.

•Pulley alignment is OK. Belt tension is OK (See page 13).

•Pads are correctly installed (See page 13).

•Blower and both pad motors are plugged into receptacles.

•All louver clips are snapped tight.
