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 both the chassis and cabinet covered with the shipping carton until all plastering, painting, and finish work
is complete and it is time to install the chassis and cabinet.
3. Verify that the 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.
GENERAL
The 50PEC water source heat pump console unit is a decentralized room terminal designed for field connection to a
closed-circuit piping loop.
Units are typically installed in perimeter zones, usually under windows. Supply air is discharged directly into the conditioned space through discharge grilles located in the top of the
unit.
IMPORTANT: The installation of console water source heat
pump units 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.
INSTALLATION
Step 1 — Check Jobsite —
stalled along an outside wall of the room. Refer to Fig. 1 and 2
for an illustration showing piping locations. Install units with
adequate clearance to allow maintenance and servicing. Refer
to Table 1 and Fig. 3-14. Locate the console unit so that it provides adequate air circulation throughout the room.
Installation, operation and maintenance instructions are
provided with each unit. Before unit start-up, read all manuals
and become familiar with the unit and its operation. Thoroughly
check out the system before operation. Complete the inspections
and instructions listed below to prepare a unit for installation.
Units are typically in-
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 filters used in these
units quickly become clogged with construction dirt and
debris which may cause system damage.
CAUTION
To avoid the release of refrigerant into the atmosphere, the
refrigerant circuit of this unit must only be serviced by
technicians who meet local, regional, and national proficiency requirements.
CAUTION
All refrigerant discharged from this unit must be recovered
without exception. Technicians must follow industry
accepted guidelines and all local, regional, and national
statutes for the recovery and disposal of refrigerants.
CAUTION
When a compressor is removed from this unit, system
refrigerant circuit oil will remain in the compressor. To
avoid leakage of compressor oil, the refrigerant lines of the
compressor must be sealed after it is removed.

Step 2 — Check Unit — Upon receipt of shipment at
the jobsite, carefully check the shipment against the bill of lading. Make sure all units have been received. Inspect the carton
or crating of each unit, and inspect each unit for damage. Ensure the shipping company makes proper notation of any shortages or damage on all copies of the freight bill. Concealed
damage not discovered during unloading must be reported to
the shipping company within 15 days of receipt of shipment.
NOTE: It is the responsibility of the purchaser to file all necessary claims with the shipping company.
STORAGE
CAUTION
DO NOT store or install console 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 units in an upright position. Tilting units on
their sides may cause equipment damage.
Upon the arrival of equipment at the jobsite, immediately
store units in their shipping cartons in a clean, dry area. Store
units in an upright position at all times. Stack units a maximum of 3 units high. Use pallets to separate each layer of
units. DO NOT remove equipment from shipping cartons
until equipment is required for installation.
UNIT PROTECTION — Cover console units on the jobsite
with either shipping cartons, vinyl film, or an equivalent
protective covering. Cap the open ends of pipes stored on the
jobsite. In areas where painting, plastering, or the spraying of
fireproof material 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 found on these
components.
Step 3 — Mount Unit
1. Unpack the unit from the shipping carton. Remove the
front cabinet by lifting up and away from the backplate.
Protect the cabinet from damage during installation by returning it to its original vinyl pack until required.
2. Remove compressor isolation plate shipping bolts (4), as
shown in Fig. 15.
3. Using a carpenter’s square and a level, ensure the unit
is level. Shim the unit if necessary to assure proper
installation.
Poor or inadequate installation may result in noisy
unit operation or unattractive appearance.
4. Select the proper fasteners to connect the backplate securely to the wall.
5. Fasten the backplate onto the wall through the screw holes
located in the back flange. Secure the subbase in place.
Step 4 — Wire Electrical Connections
WARNING
To avoid possible injury or death due to electrical shock,
open the power supply disconnect switch and secure it in
an open position during installation.
CAUTION
Use only copper conductors for field-installed electrical
wiring. Unit terminals are not designed to accept other
types of conductors.
All field-installed wiring, including the electrical ground,
MUST comply with National Electrical Code (NEC) as well as
all applicable local codes. In addition, all field wiring must
conform to the Class II temperature limitations described in the
NEC.
Consult the unit wiring diagram located on the inside of the
compressor access panel to ensure proper electrical hookup. The
installing (or electrical) contractor must make the field connections shown in Fig. 16 when using field-supplied disconnect.
Refer to unit wiring diagrams Fig. 17-29 for a schematic of
the field connections, which must be made by the installing (or
electrical) contractor. Operating voltage must be within voltage
range shown in Table 2.
Make all final electrical connections with a length of flexible conduit to minimize vibration and sound transmission to
the building.
SUPPLY VOLTAGE — Operating voltage to unit must be
within voltage range indicated on unit nameplate.
EXTERNAL LOOP POWER CONNECTION — If the unit
will be connected to an external loop pump or flow controller,
connect the pump to the loop pump terminal block PB1. The
maximum power handling is 4 amps at 240-v. The pumps will
automatically cycle as required by the unit.
230-V OPERATION — All 208/230-v units are factorywired for 208-v. The transformer wiring may be switched for
230-v operation (as illustrated on the wiring diagrams) by
switching the RED and ORG leads at L1.
