General Information
WARNING! To avoid the release of refrigerant into the
atmosphere, the refrigerant circuit of this unit must be
serviced only by technicians who meet local, state, and
federal prociency requirements.
CAUTION! To avoid equipment damage, DO NOT use
these units as a source of heating or cooling during the
construction process. The mechanical components and lters
can quickly become clogged with construction dirt and debris,
which may cause system damage and void product warranty.
⚠ WARNING! ⚠
WARNING! All refrigerant discharged from this unit must
be recovered WITHOUT EXCEPTION. Technicians must
follow industry accepted guidelines and all local, state, and
federal statutes for the recovery and disposal of refrigerants.
If a compressor is removed from this unit, refrigerant circuit
oil will remain in the compressor. To avoid leakage of
compressor oil, refrigerant lines of the compressor must be
sealed after it is removed.
⚠ WARNING! ⚠
⚠ CAUTION! ⚠
Safety
Warnings, cautions, and notices appear throughout this
manual. Read these items carefully before attempting any
installation, service, or troubleshooting of the equipment.
DANGER: Indicates an immediate hazardous situation,
which if not avoided will result in death or serious injury.
DANGER labels on unit access panels must be observed.
WARNING: Indicates a potentially hazardous situation,
which if not avoided could result in death or serious injury.
CAUTION: Indicates a potentially hazardous situation or
an unsafe practice, which if not avoided could result in
minor or moderate injury or product or property damage.
NOTICE: Notication of installation, operation, or
maintenance information, which is important, but which is
not hazard-related.
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 led
within 15 days, the freight company can deny the claim
without recourse.
Note: It is the responsibility of the purchaser to le all
necessary claims with the carrier. Notify your equipment
supplier of all damage within 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.
⚠ WARNING! ⚠
WARNING! The installation of water-source heat pumps and
all associated components, parts, and accessories which
make up the installation 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.

THE SMART SOLUTION FOR ENERGY EFFICIENCY
General Information, Cont’d.
CAUTION! All three phase scroll compressors must have
direction of rotation veried at start-up. Verication 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
signicantly reduce performance, reliability, and service life.
Always move and store units in an upright position. Tilting
units on their sides will cause equipment damage.
⚠ CAUTION! ⚠
⚠ CAUTION! ⚠
⚠ 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.
Examine all pipes, ttings, 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
con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 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. Some airow patterns are eld convertible (horizontal
units only). Locate the airow 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.
