SAFETY CONSIDERATIONS
Installation and servicing of air-conditioning equipment can
be hazardous due to system pressure and electrical components.
Only trained and qualified service personnel should install,
repair, or service air-conditioning equipment.
Untrained personnel can perform basic maintenance functions of cleaning coils and filters and replacing filters. All other
operations should be performed by trained service personnel.
When working on air-conditioning equipment, observe precautions in the literature, tags and labels attached to the unit, and
other safety precautions that may apply.
Improper installation, adjustment, alteration, service, maintenance, or use can cause explosion, fire, electrical shock or other
conditions which may cause personal injury or property
damage. Consult a qualified installer, service agency, or your
distributor or branch for information or assistance. The qualified
installer or agency must use factory-authorized kits or accessories when modifying this product. Refer to the individual
instructions packaged with the kits or accessories when
installing.
Follow all safety codes. Wear safety glasses and work
gloves. Use quenching cloth for brazing operations. Have fire
extinguisher available. Read these instructions thoroughly and
follow all warnings or cautions attached to the unit. Consult
local building codes and applicable electrical codes for special
installation requirements.
Understand the signal words — DANGER, WARNING, and
CAUTION. DANGER identifies the most serious hazards
which will result in severe personal injury or death. WARNING
signifies hazards that could result in personal injury or death.
CAUTION is used to identify unsafe practices, which would result in minor personal injury or product and property damage.
Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.
Catalog No. 04-53500075-01 Printed in U.S.A. Form 50PEC-C1SI Pg 1 9-10 Replaces: New
WARNING
Electrical shock can cause personal injury or death. Before
installing or servicing system, always turn off main power
to system. There may be more than one disconnect switch.
Turn off accessory heater power if applicable.
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
Units are typically in-
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.
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.
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.
