SKOPE OD1100N
Compressor
The cartridge is designed to be used with the specified compressor only. If you need to replace
the compressor, ensure that you use a SKOPE-specified compressor. Do not use other
compressors in this refrigeration cartridge.
The compressor is located at the front of the refrigeration cartridge, beside the condenser coil.
It must be supplied with consistent voltage over 220 volts.
If considering replacing the compressor (e.g. it’s not going):
Check all plug connections and ensure that the compressor electrics are operating
correctly.
Ensure the voltage does not drop at start-up.
If the voltage does drop, ensure the cartridge has a direct power supply (not from a
multi
-
box or extension cord).
6. Attach the replacement fan motor to the fan mounting brackets using the four nuts and spring
washers.
7. Reattach the fan motor so that the flexible cord will point towards the right side of the evaporator
tub once reinstalled. Re-cable tie the fan cord back onto the mounting bracket to prevent high
frequency vibration.
8. Place back into the evaporator tub, and ensure there is no interference between the fan motor
and evaporator tub (to prevent high frequency vibration). Trace the flexible cords back through
the evaporator tub edge transition putty and back into the electrical box area. Ensure that the
putty fills all gaps around the edge of the evaporator tub.
9. Reattach the fan blade with a 12 mm flat washer and serrated head screw. Tighten the screw to
1.5 Nm.
10. Refit the fan guard.
11. Reassemble the cartridge and test for correct operation:
•
“To diagnose lack of gas” on page 27.
•
Test and tag.
Procedure 24: To replace the evaporator fan motor (continued)
IMPORTANT
Replace the compressor with the same SKOPE OEM part.
DO NOT
use alternative parts.
IMPORTANT
To eliminate possible vibration noise, ensure no pipes touch the
evaporator tub bottom surface, evaporator tub support legs,
plastic base, or condenser coil assembly.
