General Installation
Checks
The checklist below is a summary of
the steps required to successfully
install a commercial unit. This
checklist is intended to acquaint the
installing personnel with what is
required in the installation process. It
does not replace the detailed
instructions called out in the
applicable sections of this manual.
1.
Remove packaging and inspect
the unit. Check the unit for
shipping damage and material
shortage; file a freight claim and
notify appropriate sales
representation.
Note: The 1/2 through 5 ton units
have been tied to the skid by
(2) shipping bolts. The
removal of these bolts will
require a 3/8" (9.7 mm)
ratchet with a 1/2" (12.7 mm)
socket.
The GEV 6 through 25 ton units
have been anchored to the skid
with (4) angle brackets. Remove
these brackets before lifting unit
into place.
The GEH 6 through 15 ton units
are anchored to the cross brace
of the skid with (4) wood screws.
Remove these screws prior to
lifting the unit into place.
2.
Verify the correct model, options
and voltage from the unit
nameplate.
3.
Pull out all field attached parts
(i.e. filter rack, duct collar, filter
and mounting screws) from the
unit packaging for field
mounting.
4.
Verify the installation location of
the unit will provide the required
clearance for proper operation.
5.
Remove refrigeration access
panel and inspect the unit. Be
certain the refrigerant tubing has
clearance from adjacent parts.
6.
Fabricate and install duct work
7.
Install and connect a condensate
drain line and trap to the drain
connection.

Installation
WARNING
Hazardous Voltage!
Disconnect all electric power,
including remote disconnects before
servicing. Follow proper lockout/
tagout procedures to ensure the
power can not be inadvertently
energized. Failure to disconnect
power before servicing could result
in death or serious injury.
WARNING!
Grounding Required!
Follow proper local and state
electrical code on requirements for
grounding. Failure to follow code
could result in death or serious
injury.
Main Electrical
8.
Verify the power supply
complies with the unit
nameplate specifications.
9.
Inspect all control panel
components; tighten any loose
connections.
10. Connect properly sized and
protected power supply wiring
to a field-supplied/installed
disconnect switch and to the
main power terminal block 1K1
for 1/2 through 5 ton equipment
or 1TB1 for 6 through 25 ton
equipment in the unit control
panel.
11. Install proper grounding wires to
an earth ground.
Note: All field-installed wiring must
comply with NEC and
applicable local codes.
Electric Heat Requirements
12. Verify that the power supply
complies with the electric heater
specifications on the unit and
heater nameplate.
13. Inspect the heater junction box
and control panel; tighten any
loose connections.
14. Check electric heat circuits for
continuity.
Low Voltage Wiring (AC & DC)
Requirements
15. Install the zone thermostat, with
or without switching subbase.
16. Connect properly sized control
wiring to the proper termination
points between the zone
thermostat and the unit control
panel.
Filter Installation
17. Each unit ships with 1" (25.4) or
2" (50.8 mm) filters. The quantity
of filters is determined by unit
size. The horizontal1/2 through 5
ton units requires a field
installation of the 1"/2" filter rack.
All sheet metal bracket, filter and
hardware are in a box located on
the side of the unit within the
unit packaging. All 1/2 through
25 ton verticals and 6 through 15
ton horizontal units ship with the
filter rack and filters factory
installed.
Note: Do not operate the unit
without filters.
