8. Provide an unobstructed path to the unit within the closet
or mechanical room. Space should be sufficient to allow
removal of unit if necessary.
9. Provide ready access to water valves and fittings, and
screwdriver access to unit side panels, discharge collar,
and all electrical connections.
10. Where access to side panels is limited, pre-removal of the
control box side mounting screws may be necessary for
future servicing.
STORAGE — If the equipment is not needed immediately at
the jobsite, it should be left in its shipping carton and stored in a
clean, dry area of the building or in a warehouse. Units must be
stored in an upright position at all times. If carton stacking is
necessary, stack units a maximum of 3 high. Do not remove
any equipment from its shipping package until it is needed for
installation.
PROTECTION — Once the units are properly positioned on
the jobsite, cover them with either a shipping carton, vinyl film,
or an equivalent protective covering. Cap open ends of pipes
stored on the jobsite. This precaution is especially important in
areas where painting, plastering, or spraying of fireproof mate-
rial, etc. is not yet complete. Foreign material that accumulates
within the units can prevent proper start-up and necessitate
costly clean-up operations.
Before installing any of the system components, be sure to
examine each pipe, fitting, and valve, and remove any dirt or
foreign material found in or on these components.
INSPECT UNIT — To prepare the unit for installation, com-
plete the procedures listed below:
1. Compare the electrical data on the unit nameplate with
ordering and shipping information to verify that the
correct unit has been shipped.
2. Do not remove the packaging until the unit is ready for
installation.
3. Verify that the unit’s refrigerant tubing is free of kinks or
dents, and that it does not touch other unit components.
4. Inspect all electrical connections. Be sure connections are
clean and tight at their terminations.
5. Loosen compressor bolts until the compressor rides freely
on springs. Remove shipping restraints.
6. Remove the four 1 /
4
in. shipping bolts from compressor
support plate (two bolts on each side) to maximize vibra-
tion and sound alternation.
7. Remove any blower support cardboard from inlet of the
blower.
8. Locate and verify any accessory kit located in compressor
and/or blower section.
9. Remove any access panel screws that may be difficult to
remove once unit is installed.

LEGEND
NOTE: All units have spring compressor mountings, TXV (thermostatic expan-
sion valve) expansion devices, and
1 / 2 and 3 / 4 -in. electrical knockouts.
CAUTION
DO NOT store or install units in corrosive environments or
in locations subject to temperature or humidity extremes
(e.g., attics, garages, rooftops, etc.). Corrosive conditions
and high temperature or humidity can significantly reduce
performance, reliability, and service life. Always move
units in an upright position. Tilting units on their sides may
cause equipment damage.
CAUTION
Failure to remove shipping brackets from spring-mounted
compressors will cause excessive noise and could cause
component failure due to added vibration.
