General Information, Cont’d.
CAUTION!
All three phase scroll compressors must have
direction of rotation verified at start-up. Verification 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
significantly reduce performance, reliability, and service life.
Always move and store units in an upright position. Tilting
units on their sides will cause equipment damage.

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.
Examine all pipes, fittings, and valves before installing
any of the system components. Remove any dirt or debris
found in or on these components.
Pre-Installation -
Installation, Operation, and
Maintenance instructions are provided with each
unit. Horizontal equipment is designed for installation
above false ceiling or in a ceiling plenum. Other unit
configurations are typically installed in a mechanical room.
The installation site chosen should include adequate
service clearance around the unit. Before unit start-up,
read all manuals and become familiar with the unit and its
operation. Thoroughly check the system before operation.
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 finished.
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.
Some airflow patterns are field convertible (horizontal
units only). Locate the airflow conversion section of
this IOM.
7. Locate and verify any hot water generator (HWG),
hanger, or other accessory kit located in the
compressor section or blower section.

WARNING!

WARNING!
Polyolester Oil, commonly known as POE oil, is
a synthetic oil used in many refrigeration systems including
those with HFC-410A refrigerant. POE oil, if it ever comes in
contact with the polymer drain pan, may cause the drain pan
to leak. The polymer drain pan should never come in contact
with POE oil as system failures and property damage may
result.
