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.
Inspection
Upon receipt of the equipment, carefully check the shipment
against the bill of lading. Make sure all units and accessories
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 fifteen (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 in an attic or crawl space. Other unit
configurations are typically installed in a mechanical closet
or basement. 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. Locate and verify any hanger, or other accessory kit
located in the compressor section or blower section.
Duct System Installation
The duct system should be sized to handle the design
airflow quietly. Refer to Figure 6 for horizontal duct system
details or Figure 1 for vertical duct system details. A flexible
connector is recommended for both discharge and return
air duct connections on metal duct systems to eliminate the
transfer of vibration to the duct system. To maximize sound
attenuation of the unit blower, the supply and return plenums
should include internal fiberglass duct liner or be constructed
from ductboard for the first few feet. Application of the unit
to uninsulated ductwork in an unconditioned space is not
recommended, as the unit’s performance will be adversely
affected.
At least one 90° elbow should be included in the supply
duct to reduce air noise. If air noise or excessive air flow is
a problem, the blower speed can be changed. For airflow
charts, consult catalog specifications for the series and model
of the specific unit.
If the unit is connected to existing ductwork, a previous check
should have been made to insure that the ductwork has the
capacity to handle the airflow required for the unit. If ducting
is too small, as in the replacement of a heating only system,
larger ductwork should be installed. All existing ductwork
should be checked for leaks and repaired as with the Trilogy’s
variable capacity and variable air flow duct and register sizing
is crucial for proper air delivery and throw while maintaining
acceptable sound levels.
CAUTION!
DO NOT store or install units in corrosive
environments or in locations subject to temperature or
humidity extremes (e.g., rooftops, etc. See Tables 10a
and 10b for acceptable temperature ranges). 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.
The installation of geothermal heat pump units and all
associated components, parts and accessories which
make up the GHP system shall be in accordance with the
regulations of ALL authorities having jurisdiction and MUST
conform to all applicable codes. It is the responsibility of
the installing contractor to determine and comply with ALL
applicable codes and regulations.
