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. Ensure 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
fi led within 15 days, the freight company can deny the
claim without recourse. Note: It is the responsibility of the
purchaser to fi le 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 chassis in an upright
position at all times. Stack units at a maximum of 2 units high.
Store cabinets horizontally, keeping them on their pallets
to protect the risers. Do not stack multipacks. Stack single
cabinets at 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. All openings in cabinet
must be covered during all stages of construction. Physical
damage and contamination may prevent proper start-up
and may result in costly equipment clean-up.
Examine all pipes, fi ttings, and valves before installing
any of the system components. Remove any dirt or debris
found in or on these components.
Prior to fl ushing risers with water, be sure that the
temperature in building will always be above freezing.
Pre-Installation -
Installation, Operation, and
Maintenance instructions are provided with each unit.
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 cabinet 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. Each cabinet has a tag to indicate the location to be
installed and the riser diameter.
3. Keep the cabinet openings and exposed sheet
metal covered until installation is complete and all
plastering, painting, etc. is fi nished.
4. Inspect all electrical connections. Connections must
be clean and tight at the terminals.
Prepare chassis for installation as follows:
1. Verify refrigerant tubing is free of kinks or dents and
that it does not touch other unit components.
2. Inspect all electrical connections. Connections must
be clean and tight at the terminals.
3. Remove compressor shipping clips, bracket, or screws.
See chasss pre-installation section for instructions.
4. If chassis is not installed in cabinet, store in
original carton.
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!

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.
