Jobsite Storage
This unit is intended for indoor use
only. To protect the unit from damage
due to the elements, and to prevent
possible IAQ contaminant sources
from growing, the unit should be
stored indoors. If indoor storage is
not possible, the following provisions
for outdoor storage must be met.
1. Place the unit(s) on a dry sur-
face or raise above the ground
to assure adequate air circula-
tion beneath the unit. This is to
assure that no portion of the unit
contacts standing water at any
time.
2. Cover the unit(s) with a water
proof tarp to protect them from
the elements.
3. Make provisions for continu-
ous venting of the covered
units to prevent moisture from
standing on the unit(s) sur-
faces. Wet interior unit insulation
can become an amplification site
for microbial growth (mold) which
has been determined to be a
cause of odors and serious
health related indoor air quality
problems.
4. Store units in the normal UP
orientation. Storing units in this
manner maintains oil in the com-
pressor.
5. Units may be stacked two high.
Pre-installation
Checklist
Jobsite Inspection
Each unit has been inspected, tested
and operated at the factory by pro-
duction and quality associates prior
to being crated for safe transit. How-
ever, rough handling or accidents
can occur resulting in damaged
equipment being delivered. Always
perform the following checks before
accepting a unit:
1. Do not sign the bill of lading
accepting the unit(s) until
inspection has been com-
pleted. Check for damage
promptly after the unit(s) are
unloaded. Once the bill of lading
is signed at the jobsite, the unit(s)
are now the property of the SOLD
TO party and future freight claims
MAY NOT be accepted by the
freight company.
2. Check the unit model numbers
on the bill of lading against
those ordered and received to
assure equipment is AS
ORDERED.
3. Check to assure that the refrig-
erant charge has been retained
during shipment by use of
gauges. Schrader taps are
located and labeled internal to
the cabinet. (See Figure 1).
Figure 1: Schrader location

LOW
IMPORTANT!
After assuring that charge has been retained:
Reinstall schrader caps to assure that refrigerant
leakage does not occur.
Reinstall unit panel using all factory provided
screws.

Access to the unit for servicing purposes should be provided at installation. All configurations require clear-
ance from other mechanical and electrical equipment on three service sides (shown below). This enables
panel removal from the unit for service/maintenance ability.

Uncrate Unit
Remove packaging and inspect the unit. Carefully re-
move the stretch wrap and cardboard pieces. The in-
stallation literature and Torx®head tool may be found
on the back of the unit in a clear baggie. Unit has been
tied to skid by (2) shipping brackets.
Inspect Unit
Remove refrigeration panel and inspect the unit. Be
certain the refrigerant tubing has clearance from adja-
cent parts. Verify that the electrical connections are
tight and in-place.
Mounting to Wall
With the chassis still on the subbase, align the unit to
the wall. If unit contains an outside air option, align the
wall cut-out to the subbase outside-air cut-out. Level
the unit per plan requirements. Mark the four mount-
ing locations for wall sleeve mounting to the wall. The
dimensions should fall in line with Step 5.
Remove Chassis
Remove the chassis from the subbase via 6-Torx head
screws. The chassis is attached to both the subbase
and the wall sleeve (see diagram above). To assure
proper alignment, re-install screws 2 and 3 in the final
installation of the unit (Step 11).

Wall Flange
After removing chassis from the subbase, install the
wall flange assembly to the desired wall with the use
of four #10-field provided screws. The wall flange as-
sembly includes four, 1/4-inch in diameter clearance
holes.
Mounting of Disconnect
(circuit breaker-OPTION)
Mounting of the circuit breaker/receptical box should
be made prior to piping and electrical hook-up. This
factory disconnect option is designed to fit inside the
end pocket. Mount the electrical box flush with the
subbase with four, #8-field supplied screws.

Mounting of Disconnect
(receptical box-OPTION)
Mounting of the receptical box should be made prior
to piping and electrical hook-up. This factory discon-
nect option is designed to fit inside the end pocket.
Mount the receptical box 2-inches above the top of the
subbase with four, #8-field supplied screws.

Wiring of Disconnect
(OPTION)
Power wiring to the equipment should be installed per
national and local electric codes by a professional
electrician.
Power wiring to the disconnect may be done at this
time. See the unit’s wiring schematic for field wiring.
