Important information on air
conditioner repairs and spare
part storage
Note! Moisture is the worst enemy of any air conditioner.
1. Keep all spare parts sealed and store in a dry place.
2. Immediately make all connections air tight when interrupt-
ing the refrigerant circuit.
3. Before installation purge refrigerant hoses with nitrogen or
refrigerant.
4. When installing parts, do not remove plugs until shortly
before assembly. This is especially important for the drier. A
drier, which is not sealed, quickly becomes saturated and
cannot be used.
5. Do not pump refrigerant from the air conditioner back into
the cylinder.
6. Always keep empty refrigerant cylinders closed.
7. Only buy refrigerant from specialized dealers.
8. Do not carry out repairs outdoors in damp weather.
9. Always replace drier receiver after interrupting the refriger-
ant circuit.
10. The presence of moisture in the refrigerant circuit does not
only lead to a poor cooling output but also to the decomposi-
tion of the solid ---state drier and the decay of the refrigerant
lines due to acid formation. Expensive repairs and down ---
time are the result.
11. Before starting, check oil level of the compressor and
evacuate refrigeration circuit according to instructions given.
Time of evacuation 1 ---4 hours. Dry refrigeration circuit at least
once by breaking the vacuum with liquid refrigerant.
