signifies hazards that could result in personal injury or death.

CAUTION is used to identify unsafe practices, which would re-

sult in minor personal injury or product and property damage.

GENERAL

The 50PEC water source heat pump console unit is a decen-

tralized room terminal designed for field connection to a

closed-circuit piping loop.

Units are typically installed in perimeter zones, usually un-

der windows. Supply air is discharged directly into the condi-

tioned space through discharge grilles located in the top of the

unit.

INSTALLATION

Step 1 — Check Jobsite —

Units are typically in-

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 pro-

vides 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 cor-

rect unit has been shipped.

2. Keep both the chassis and cabinet covered with the ship-

ping 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.

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.

IMPORTANT: The installation of console water source heat

pump units and all associated components, parts, and acces-

sories 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 respon-

sibility of the installing contractor to determine and comply

with ALL applicable codes and regulations.

CAUTION

To avoid equipment damage, do not use these units as a

source of heating or cooling during the construction pro-

cess. 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 profi-

ciency 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.
