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 the package of hanger grommets (shipped
inside of the blower outlet) and retain for use with the
hanger brackets when mounting the unit.
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 may cause equipment damage.
