2. Isolate the leak in the coil/evaporator in the identified case by using pressurized air set at
no more than 10 psi and a soap and water solution and a brush. Brush the solution over the
coil/evaporator until the area that is leaking has been identified. Identify the area that is
leaking with a grease pen or by the use of another available marking pen.
3. Clean the area around the leak with a mild detergent and water or another commercially
available cleaning solvent.
4. Ensure the area around the leak is completely dry and free of all oil and grease.
5. Solder the area that was identified as leaking using good commercial practices. Contact
your Kysor//Warren Service Representative if there are any questions regarding the type of
solder to be used or the actual repair.
6. Verify the leak has been repaired, take the case out of isolation, and charge the system.
Refer to the Parallel Compressor Units Operation and Maintenance Manual, Part Number
31E08001.
Electrical Connections
The following procedure is for the field repair of the electrical connections. If the case has
electrical problems, perform the following:
1. Identify the case with the electrical problem and remove power to that case.
2. Refer to that case electrical diagrams provided in this manual.
3. Check all fittings within that circuit to ensure the plugs are properly mated and there is no
corrosion present on the pins and sockets of the plug or the mating connector.
4. If the plugs are properly mated and there is no corrosion present, use a digital multimeter to
ohm each set of wires for the circuit that is inoperable, starting at the beginning and
termination point for each circuit. Look for an open (infinity read on the meter). It is
common practice to continue to isolate the circuit by following the wire back to the
origination point and continuing to ohm the wire at each connection point.
5. Once the wire has been traced and the area requiring repair identified, repair the wire using
good, commercial electrical practices. Contact your Kysor//Warren Service Representative
if there are any questions regarding the actual repair.
6. Re-apply power to the case and verify the electrical system has been repaired.
