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 that are 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.
The EXHF 0.75 to 6 tons and DXHF 2 to 6 ton units
have been anchored to the skid by (2) shipping
bolts. The removal of these bolts will require a 3/8
(9.7 mm) ratchet with a 0.5 (12.7 mm) socket.
The EXVG 0.75 to 6 tons and DXVG 2 to 6 tons have
been anchored to the skid with (4) angle brackets.
Remove these brackets before lifting 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.

1. Verify the power supply complies with the unit
nameplate specifications.
2. Inspect all control panel components; tighten any
loose connections.
3. Connect properly sized and protected power supply
wiring to a field-supplied/installed disconnect
switch and to the main compressor contactor/
power block 1K1 for DXH/V 2 to 6 tons and EXH/V
0.5 to 6 ton units.
4. Install proper grounding wires to an earth ground.
DXH and EXH 460 V units require a neutral (a four
wire system).
N No otte e:: All field-installed wiring must comply with NEC
and applicable local codes.
Electric Heat Requirements
1. Verify that the power supply complies with the
electric heater specifications on the unit and heater
nameplate.
2. Inspect the heater junction box and control panel;
tighten any loose connections.
3. Check electric heat circuits for continuity.
Low Voltage Wiring (AC)
Requirements
1. Install the zone sensor or thermostat.
2. Connect properly sized control wiring to the proper
termination points between the zone thermostat or
sensor and the unit control panel.
Filter Installation
Each unit ships with 1 (25.4 mm) standard, 2 (50.8 mm)
standard, 2 in. MERV 8 or 2 in. MERV 13 filter. The
quantity of filters is determined by unit size. The EXH
and DXH units require field installation of the 1" or 2"
filters rack. All sheet metal bracket, filter and hardware
are in a box located on the side of the unit within the
unit packaging. All vertical units ship with the filter rack
and filters factory installed.
