SECTION 4
4.0 MAINTENANCE
ELECTRIC SHOCK CAN KILL. Precautionary measures should be taken to
provide maximum protection against electrical shock. Be sure that all
primary power to the machine has been externally disconnected. Open
wall disconnect switch or circuit breaker before attempting inspection or
work inside the circulator. Install all covers after completing service. Do
not operate unit without covers. If this equipment does not operate prop-
erly, stop work immediately and investigate the cause of the malfunction.
Maintenance work must be performed by an experienced person, and
electrical work by a trained electrician. Do not permit untrained persons
to inspect, clean, or repair this equipment. Use only recommended re-
placement parts.
If this equipment does not operate properly, stop work immediately and investi-
gate the cause of the malfunction. Maintenance work must be performed by an
experienced person, and electrical work by a trained electrician. Do not permit
untrained persons to inspect, clean, or repair this equipment. Use only recom-
mended replacement parts.
1. Maintain coolant level by observing the indicator window. When dark, coolant
is at a safe level; when clear, add more coolant.
2. Periodically remove the large 15/16" acorn nut from the pump and check the
filter screen (951346) for sediment. Clean the filter or replace if necessary.
3. Periodically empty and flush the reservoir.
4. To insure optimum performance of the circulator, remove dust from the radiator
by means of compressed air.
5. The motor is equipped with a thermal overload protection. If motor stops,
switch power off and wait at least 5 minutes. Then switch power on. If motor
runs, the motor was shut off by the thermal overload protection. If it does not
run, then check motor for damage.
6. Oil both motor bearings (yellow oil plug) once a year for heavy usage with SAE
20 oil.
