Installation, Operation and Maintenance Manual
NOTICE. The area should be vented thoroughly to prevent formation of
dangerous fumes which could result from the refrigerant in the presence of an
open flame.
7. Remove the mounting bolts which will be reused during compressor replacement and lift the compressor
out of the unit.
8. Remove the crankcase heater which will be reused during compressor replacement
9. Depending on the type of compressor failure, refrigerant components such as filter drier, refrigerant
receiver or refrigerant oil separator may need to be replaced. Check these components before servicing the
compressor.
10. If the replaced compressor is to be returned, it must be properly sealed to prevent the compressor oil from
leaking during return shipment.
11. Allow the compressor to remain open to the atmosphere for 15 minutes to ensure that the compressor oil
is completely degassed.
12. Do not hammer the compressor suction and discharge tube fittings flat and braze them closed. These
fittings must remain undamaged, so the compressor can be tested by Data Aire Service Department.
13. Braze in short stub tubes to the compressor connections and seal the stub tube ends. Braze with Sil-Fos or
equivalent silver copper phosphorus composition brazing material. No soldering allowed.
Brazing in the Compressor
1. Mount the original crankcase heater to the compressor housing and secure in place.
2. Lift the compressor into place and secure with the original mounting bolts.
3. The copper coated steel tubes on the scroll compressor can be brazed in virtually the same manner as any
copper tube. Any silver-phosphorous copper brazing material with a minimum of 5% silver is preferred;
however, 0% silver is still acceptable.
4. The following procedure should be used to braze the tubes to the compressor:
a. Be sure the tube fitting I.D. and tube O.D. are free of oil and clean prior to assembly.
