A. DAILY INSPECTION SCHEDULE |
|
1. Check all motors for overheating.
2. Check the temperature of all motor bearings.
3. Check the oil level in the crankcases of the
compressors two or three times a day; if
|
|
the level is low, new oil should be added.
4. Check for excessively high and low refrigerant pressures.
5. Check the crankcases for low temperatures
or excessive Freon 12.
|
|
B. WEEKLY INSPECTION SCHEDULE |
|
1. Check all fans for unusual noise and vibration.
2. Check all regularly operated valves and
compressor seals for leaks.
3. Check proper tension of V-belts.
4. Check the oil level on motor bearings add
oil if necessary.
|
|
5. Check all ball bearings; add grease when
necessary.
6. Check the oil level in fan bearings; add oil
if necessary.
7. Check the flywheels and pulleys.
8. Clean the evaporator coils if dirty.
9. Clean and dust all equipment.
|
|
C. MONTHLY INSPECTION SCHEDULE |
|
1. Check the compressors for any unusual
vibration; check the mountings.
2. Check the clearance between rotor and
stator on all motors.
3. Check the V-belts for wear, and clean off
all oil and dirt.
4. Check entire systems carefully for refrigerant leaks.
5. Check and clean all automatic control and
safety devices, also all switch contacts.
|
|
6. Check and clean the condenser tubes when
refrigerant or water temperatures indicate
the need.
7. Inspect the evaporator coils; clean at least
every three months; oftener if necessary.
8. Check all pressures and temperatures
throughout all systems, valves, and devices.
9. Inspect the zinc fingers in the condensers;
replace when deteriorated 30 percent or
more.
|
|
D. YEARLY INSPECTION SCHEDULE |
|
1. Remove motor and bells; check and clean
windings.
2. Wash out all motor bearings, and refill with
new motor oil.
3. Wash out all fan bearings; check clearance;
refill with new oil.
4. Test insulation of motor leads and windings.
5. Check rusting of metal parts on all equipment;
|
|
repair piping and equipment when
ever necessary.
6. Drain crankcases of compressors, and wash
out thoroughly.
7. Test all gages.
8. Inspect all insulation coverings of cold
pipes, especially seams. Replace all rusted
binding wires and rotted covering cloths;
add seam-filler where necessary.
