8.2.1.5 ELECTRICAL WIRING
: The electrical wiring can, over time, become worn and
damaged. If the wiring insulation is showing signs of abrasion or damage of any other
kind, replace wiring as required
8.2.1.6 RECEIVER DRYER ASSEMBLY
: The receiver dryer assembly can, over time,
become damaged. The component can also become contaminated due to damaged,
opened, cracked, or ruptured lines or hoses. If the receiver dryer shows signs of
damage, it should be removed and replaced. If the receiver dryer has been
contaminated, it must be removed and replaced (refer to Disassembly, Section 5 and
Assembly, Section 9). Contact Enviro Systems customer service to order a new
receiver dryer
8.2.1.7 FAN / OUTLET SHROUD
: The fan / outlet shrouds can, over time, show signs of
cracking and separation between the shrouds and the condenser. This can cause the
compressor condenser module assembly to have less than optimal performance. If
the shrouds are separating, refer to Disassembly (Section 5) for removal. Then refer
to Cleaning (Section 6). After insuring that the seam between the shrouds and
condenser have been cleaned according to the cleaning procedures (Section 6), apply
a new bead of RTV and reinstall shrouds (refer to Assembly, Section 9). Allow RTV to
cure for a minimum of 24 hours before operating system. If the shrouds are cracked
or are damaged in any other way, they should be replaced. Contact ENVIRO
Systems customer service to order new components.
8.2.1.8 CONDENSER COIL
: The condenser coil fins can, over time, become clogged with
dirt, dust, and other foreign matter. The component can also become damaged. The
coil return bends can, over time, become damaged. Dents, nicks, cracks, and other
damage can cause less than optimal performance. It is essential that the condenser
coil remain clear and undamaged for proper operation. Refer to Cleaning (Section 6)
for proper cleaning procedures. If coil fins are bent, use a fin comb and try
straightening the fins. If fins are excessively damaged or the return bends are
excessively damaged, the entire compressor condenser module assembly must be
removed (refer to Disassembly, Section 5) and sent to Enviro Systems for repair.
Contact Enviro Systems customer service.
8.2.1.9 HOUR METER
: The hour meter can, over time, become damaged or show signs of
improper operation. If the hour meter is damaged or not operating correctly, remove
and replace (refer to Disassembly, Section 5 and Assembly, Section 9).
