CAUTION!
All three phase scroll compressors must have
direction of rotation verifi ed at start-up. Verifi cation is achieved by
checking compressor Amp draw. Amp draw will be substantially
lower compared to nameplate values. Additionally, reverse rotation
results in an elevated sound level compared to correct rotation.
Reverse rotation will result in compressor internal overload trip
within several minutes. Verify compressor type before proceeding.
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
signifi cantly reduce performance, reliability, and service life.
Always move and store units in an upright position. Tilting
units on their sides may cause equipment damage.
NOTICE! Failure to remove shipping brackets from spring-
mounted compressors will cause excessive noise, and could
cause component failure due to added vibration.

CAUTION! CUT HAZARD - Failure to follow this caution
may result in personal injury. Sheet metal parts may have
sharp edges or burrs. Use care and wear appropriate
protective clothing, safety glasses and gloves when
handling parts and servicing heat pumps.
Prepare units for installation as follows:
1. Compare the electrical data on the unit nameplate with
ordering and shipping information to verify that the correct
unit has been shipped.
2. Keep the cabinet covered with the original packaging until
installation is complete and all plastering, painting, etc. is
fi nished.
3. Verify refrigerant tubing is free of kinks or dents and that it
does not touch other unit components.
4. Inspect all electrical connections. Connections must be
clean and tight at the terminals.
5. Remove any blower support packaging (water-to-air units
only).
6. Loosen compressor bolts on units equipped with
compressor spring vibration isolation until the compressor
rides freely on the springs. Remove shipping restraints.
7.
REMOVE COMPRESSOR SUPPORT PLATE 1/4”
SHIPPING BOLTS (2 on each side) TO MAXIMIZE
VIBRATION AND SOUND ATTENUATION (R22
units only).
8.
Some airfl ow patterns are fi eld convertible (horizontal
units only). Locate the airfl ow conversion section of this
IOM.
9. Locate and verify any hot water generator (HWG), hanger,
or other accessory kit located in the compressor section or
blower section.
