GENERAL
Omnizone™ single package cooling units are designed to provide
the flexibility required in replacement, renovation, and new con-
struction. Units are available in 6 sizes from 5 tons to 20 tons.
The 50XCW units are water-cooled units with factory-supplied
plate and frame, water-cooled condensers.
These
vertical pack-
aged units are fully piped and wired.
See Fig. 1-13 for unit dimensions and refer to Table 1 for unit op-
erating weights. Applicable installation codes may limit this cabi-
net to installation only in a single-story residence.
INSTALLATION
Omnizone 50XCW units are intended for indoor installation only.
Determine building alterations required to run piping, wiring and
ductwork. Follow dimensional drawings for ductwork, piping lo-
cations, electrical wiring and overall unit dimensions. Read all in-
stallation instructions before installing the unit.
Step 1 — Complete Pre-Installation Checks
Examine unit for damage incurred during shipment. File claim im-
mediately with transit company if damage is found. Check the
shipment for completeness. Verify that the nameplate electrical re-
quirements match the available power supply.
DO NOT place the unit in a horizontal position that would allow
oil to drain into the top of the compressor. Do not allow refrigerant
lines to come into contact with wiring or sharp objects or edges.
Do not lift or move unit by putting pressure on refrigerant lines.
CAUTION
DO NOT re-use compressor oil or any oil that has been ex-
posed to the atmosphere. Dispose of oil per local codes and
regulations. DO NOT leave refrigerant system open to air
any longer than the actual time required to service the
equipment. Seal circuits being serviced and charge with dry
nitrogen to prevent oil contamination when timely repairs
cannot be completed. Failure to follow these procedures
may result in damage to equipment.
