COOLER MOTOR

WARNING: FAILURE TO FOLLOW

INSTRUCTIONS AND USE SAFE ELEC-

TRICAL PROCEDURES COULD RESULT

IN SERIOUS INJURY SUCH AS SHOCK

OR ELECTROCUTION.

SAFETY PRECAUTIONS

1. Disconnect electrical power at

source before working on or

near a motor or its connected

load.

2. This motor must be grounded

by attaching the power supply

green ground wire to the motor

terminal green screw.

3. Caution: Motor may stop and

restart without warning.

If motor is “overloaded”, it will

become unusually hot and the

automatic internal overload

switch will cause the motor to

stop. The motor will then

automatically restart after

cooling down. An “overloaded”

motor will cycle on and off. If

this occurs, see Motor Pulley

Adjustment section.

4. Install all wiring, fusing and

grounding in accordance with

National Electrical Code, local

requirements, and according to

cooler manufacturer’s instruc-

tions.

5. Keep all parts of body and loose

clothing clear from belts,

pulleys and other exposed parts

at all times.

MOTOR INSPECTION

1. Examine motor thoroughly to be

sure it was not damaged in

shipment.

2. Check the motor shaft. It should

rotate freely when turned by hand.

3. Check nameplate rating. Voltage

and frequency must match the

electrical power source. Motor

H.P. must be suitable for your

cooler size.

MOTOR PULLEY SELECTION

The motor pulley must

be the same

size and type recommended by cooler

manufacturer. Do not

use a larger

pulley size. Recommended motor

pulley sizes are:

1/3 HP Motor:

3¼" adjustable, or

2¼" to 2

½" fixed

with

½" bore.

1/2 HP Motor:

½" to 3¾"

adjustable, or 2½"

to 2

¾" fixed with ½"

bore.

3/4 HP Motor:

¾" adjustable, or

3" to 3

¼" fixed with

½" bore.

1 HP Motor:

(Single Inlet

Coolers Only)

4" adjustable, or

3¼" to 3

½" fixed

with 5/8" bore.

IMPORTANT: Too large of a motor

pulley will “overload” motor and cause

it to cycle on and off. If this occurs,

see Motor Pulley Adjustment section.

INSTALLATION INSTRUCTIONS

1. Motor Mounting:

Place motor in motor mounting bracket

with vent holes down and motor label

up. Be sure groove in rubber mounting

rings seats securely on mounting

bracket. Tighten clamps.

2. Motor Pulley and Blower Pulley

Alignment:

Pulleys must be aligned per Figure 1.

If necessary, loosen pulley set screws

with 5/32 Allen wrench. Each set

screw must seat securely on flat of

shaft.

Align Motor and Blower Pulley

with V-Belt in Place

(Figure 1)

3. Belt Tension:

Adjust belt to deflect 1/2 to 3/4 inch at

center of span as per Figure 2.

Readjust belt tension after any pulley

adjustment. Replace worn or damaged

belts.

Adjust Belt Tension

(Figure 2)
