Console Model
INTRODUCTION:
The console water source heat pumps are designed for
use as decentralized room terminals that are field
connected to a closed- circuit piping loop within a
structure. Typically these units are installed in perimeter
zones and are ideal for installations where ducted
systems are impractical.
All units are designed for boiler/tower systems
geothermal closed loop applications and can operate
with fluid temperatures as low as 25°F in heating and as
high as 110°F in cooling. Units are available in 3/4, 1,
1-1/4 and 1-1/2 tons nominal capacity in cooling. Refer
to the unit specification sheet for precise performance
figures at various entering air and water conditions.
NOTE: Console units are designed for indoor
installation in the conditioned space only. Do
not install outdoors, in attics or in any other
location that would subject the unit to extreme
temperature or humidity or to corrosive
environments. Doing so will inhibit
performance, reliability and service life of the
unit.
SAFETY CONSIDERATIONS:
Installation and servicing of this system can be
hazardous due to system pressure, electrical
components and moving par ts. Only trained and
qualified service personnel should install and service
this equipment. Untrained personnel can per form basic
maintenance such as cleaning coils/cabinet or replacing
filters.
WARNING: Before per forming service or
maintenance operations on system, turn off
main power to unit. On units with unit mounted
controls, the On/Off switch DOES NOT
disconnect the unit from main power. High
voltage components or moving parts can
cause injury or death.
When working on this equipment, always observe
precautions described in the literature, tags and labels
attached to the unit. Follow all safety codes. Wear safety
glasses and work gloves. Use a quenching cloth for
brazing operations and place a fire extinguisher close to
the work area.
This unit is designed to be operated with the cabinet,
sub base and filter in place. Never operate unit without
the cabinet and filter in place or with open access
panels. Doing so can expose the operator to hazardous
voltage and moving parts and can damage the
equipment.

INITIAL INSPECTION, MOVING AND
STORAGE:
Inspect the carton or packaging of each console unit as
it is received at the job site and before signing the freight
bill. Note any damage or shortage on all copies of the
freight bill. Concealed damage must be reported to the
carrier within 24 hours of receipt.
Unit wiring diagrams and Installation/Operation
manuals are provided with each unit. Read these
manuals prior to star t up to become familiar with the
unit and its operation.
Caution
Take care when moving the unit as most of the unit's
weight is located on the left (compressor) end. Always
store and move unit in an upright position. Take care to
protect the unit cabinet and sub base when moving or
storing. Never move or lift unit by its water connections.
If the equipment is not needed for immediate
installation, it should be stored in its original packaging
in a clean, dry area. Units must be moved and stored in
an upright position, never lay the unit on it's side. When
storing, do not stack units.
INSTALLATION:
Before installing the unit, examine each pipe, fitting and
valve; remove any dirt or debris found on or in these
components. Use care when installing the system
components to avoid damage to the cabinet finish or
chassis.
1.
After removing the console unit from its packaging
remove the cabinet by removing the cabinet screws
on either side of the unit and lifting the cabinet off
the chassis. Set the cabinet aside and cover it (the
console unit 's pack aging can be used for this
purpose).
2.
Position the sub base directly on the finished floor.
Make sure the sub base is level (use shims if
necessary). The sub base has a frame that supports
the cabinet and may be secured to wall.
3.
Position the chassis onto the sub base. Check and
align electrical, water and condensate connections
and secure to the sub base with 4 screws.
4.
Before connecting the unit to water, make sure that
the loop has been properly flushed. After flushing
the system, connect piping or hoses to the proper
supply, return and condensate connections. Refer to
the piping section of this manual for more
information
Subject to change without prior notice
Note that an Installation/start-up checklist is
provided at the end of this manual to
encourage thorough unit check- out at
start-up.
