General Information
Inspection
Upon receipt of the equipment, carefully check the shipment
against the bill of lading. Make sure all units have been
received. Inspect the packaging of each unit, and inspect each
unit for damage. Insure that the carrier makes proper notation
of any shortages or damage on all copies of the freight bill and
completes a common carrier inspection report. Concealed
damage not discovered during unloading must be reported
to the carrier within 15 days of receipt of shipment. If not filed
within 15 days, the freight company can deny the claim without
recourse. Note: It is the responsibility of the purchaser to file
all necessary claims with the carrier. Notify your equipment
supplier of all damage within fi fteen (15) days of shipment.

Storage

Equipment should be stored in its original packaging in a
clean, dry area. Store units in an upright position at all times.
Stack units a maximum of 3 units high.
Unit Protection
Cover units on the job site with either the original packaging
or an equivalent protective covering. Cap the open ends
of pipes stored on the job site. In areas where painting,
plastering, and/or spraying has not been completed, all due
precautions must be taken to avoid physical damage to the
units and contamination by foreign material. Physical damage
and contamination may prevent proper start-up and may
result in costly equipment clean-up.
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 confi gurations 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
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 grommet vibration isolation until the
compressor rides freely on the grommets.

7. Locate and verify any hot water generator (HWG), hanger,
or other accessory kit located in the compressor section
or blower section.
CAUTION!
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.
CAUTION!
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.
