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. Verify that the unit is the correct model for the entering
water temperature of the job.
3. Do not remove the packaging until the unit is ready for
installation.
4. Verify that the refrigerant tubing is free of kinks or dents,
and that it does not touch other unit components.
5. Inspect all electrical connections. Be sure connections are
clean and tight at the terminals.
6. Loosen compressor bolts until the compressor rides freely
on springs. Remove shipping restraints.
7. Remove the four

in. shipping bolts from compressor
support plate (two bolts on each side) to maximize vibra-
tion and sound alternation.
8. Remove any blower support cardboard from inlet of the
blower.
9. Locate and verify any accessory kit located in compressor
section.
10. Remove any access panel screws that may be difficult to
remove once unit is installed.
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.
Failure to remove shipping brackets from spring-mounted
compressors will cause excessive noise and could cause
component failure due to added vibration.
