Determine the best location for mounting
the indoor unit, it must be located a mini-
mum of 4 ft (6 ft or more recomended) from
the floor and no less than 6” from ceiling.
CONTROLS AND COMPONENTS
Units are supplied with a wireless remote
control, which communicates with the unit
microprocessor control. The return air
temperature sensor mounted in the in-
door unit provides input to the control for
system operation.
Pay attention to the air circulation in the
room, 9,000 & 12,000 Btuh units throw air
15ft, 18,000 & 24,000 Btuh units throw air
25ft, ensure no obstacles to airflow exist.
Several modes of operation are available
to the end user depending on the type of
comfort required. All unit operating func-
tions are controlled via the remote con-
trol. Refer to “System Operation” section
of this manual.
Locate the indoor and outdoor units as close
together as possible, maximum line set run
and lift MUST NOT BE EXCEEDED. Deter-
mine how the interconnect piping, wiring
and condensate hose are to be run.
OPTIONAL CONTROLS AND
COMPONENTS
Lift
Low Ambient Control:
Please consult the factory for availability of
approved method of low ambient cooling
operation.
Condensate Pump:
It is recommended to use the supplied
condensate drain hose in a gravity fed
method whenever possible. If this can
not be done then a field installed pump
that is external to the evaporator would
be required.
Ensure that all panels can be removed for
service as required.

INDOOR UNIT INSTALLATION
Prepare the evaporator for mounting
by removing the mounting bracket from
the rear of the indoor unit. Use a Phillips
head screwdriver to remove the unit pipe
strap. If the unit is a heat pump the de-
frost sensor also must be undone from its
retainer.
If mounting the unit on an inside wall, use
the knockouts provided on the left and
right sides of the unit to route the piping
and wiring connections through.
The indoor unit weighs a maximum of
20 Lbs. Use wall anchors to secure the
mounting bracket to a wall stud and en-
sure that the wall is capable of holding the
weight of the unit.
If mounting the unit on an outside wall
measure from the edges of the unit to the
center of the line set 90° bend to locate the
the center of the wall penetration. Drill a
3” ø hole through the wall. Angle the wall
penetration slightly down towards the out-
side to assist in draining the condensate
away from the unit.
Be sure mounting bracket is level, so that
the condensate can drain properly.

INDOOR UNIT INSTALLATION
Prepare unit line set connections
Rotate refrigerant line stubs gently to 90°
(if mounting on an outside wall). For oth-
er line set configurations align the stubs
as required.
Feed the 14 AWG interconnect wiring
between indoor and outdoor through
the unit electrical connection (maxi-
mum number of 6 wires is required) (if
required by local codes an electrical
connector can be attached to the rear
of the unit). Tape the loose wire to the
line set stubs. (See Electrical Wiring In-
stall section.) These two tips save time
and prevent damage to the stubs when
mounting the indoor unit.
Tip: Use Duct tape to tape the Con-
densate hose (make sure it is below
the Line set stubs) and the defrost
sensor (heat pump only). This makes
it easier to guide them through the
hole in the wall.
HEAT PUMP SYSTEMS
Very Important! Make sure the de-
frost sensor wire is run and connected
between the indoor and outdoor units,
or the heat pump system will not oper-
ate in heat mode. Refer to “Heat Pump
Wiring” section of this manual.

Indoor unit is now installed, it should be
plumb, level and flush with the wall. Insure that the line set stubs are completely
OUTDOOR UNIT INSTALLATION
Locate Outdoor unit
Select a location with proper ventilation,
minimizing recirculation possibility. Do not
install the outdoor unit in a location ex-
posed to high winds (field fabricated and
installed wind baffle may be required).
Ensure location does not impede access
around unit and pose a disturbance to
neighboring areas.
Install the outdoor unit on a condenser
service pad. If unit is a heat pump ex-
tend feet to raise 6” to allow for defrost
to drain away.

Refrigerant Line Set Piping
Interconnecting line set between th e
outdoor unit and the indoor unit, must have
both refrigerant lines insulated as the
expansion device is located in the outdoor
unit.
Gently bend the line set stubs from the
in- door unit to the desired location.
Using 2 x 10”/12” Crescent wrenches
remove the flare nuts from the indoor
unit line stubs.
The indoor unit is filled with a dry
gas, check for release of this to ensure
that no leaks are present. Use a small
amount of vacuum pump oil on the male
flare threads to ease installation.
Connect the line set to the stubs.
Using the 2 wrenches, 1 on the male
and 1 on the female tighten the flare
nuts. Run the line set to the outdoor
unit, avoid tight bends and kinking
the lines.
If line set length is in excess of that
re- quired, cut line set and re-flare or
coil ex- cess vertically to facilitate oil
return to the compressor.

Evacuation
Gauges can now be attached to the service
ports - SERVICE PORTS HAVE A 5/16”
CONNECTION TO GAUGES, which is dif-
ferent from the norm for R-22. You will need
specific hoses or an adaptor for the 5/16”
connection.
Once the gauges are attached the line
set can be leak checked using Nitrogen
at 300 psig. Evacuate the unit and inter-
connect down to a minimum of 400-500
Microns, break vacuum with Nitrogen to
further leak check.
Re-evacuate the system down to 300-400
Microns or lower for a period of one hour.
This is an R-410A System it is essential
that a deep vacuum be pulled on the sys-
tem to remove all traces of moisture. See
“System Start-Up” section to fine-tune the
refrigerant charge.
Main Power Wiring
Electrical wiring should be done in accordance with all National Electrical Code
(NEC) and local state/city building codes.
Note: A small screwdriver is required
for unit terminals.
Breaker size and wiring must be sized
for the rating plate amperage, MCA and
HACR. Use only HACR type breakers,
each system installed must have a sep-
arate branch

tion. Ground connection must be made to
the terminal plate.
Heat Pump (208/230 V) unit terminals:
L1 - L2 : Power from breaker + G
L3 - L4 : Power to indoor unit + G
1 - 2 - 3 : Control signals
These are just examples of typical wiring
connections. Always refer to Wire Diagram
on unit for actual wiring connections.
A local disconnect should be installed ad-
jacent to the outdoor unit in accordance
with National and Local Codes. The out-
door unit provides power for the indoor
unit, no disconnect is required between
the outdoor and indoor units.
Line voltage from the disconnect should
be wired to:
N - L (115V Unit), + G
L1 - L2 (208/230V Unit), + G
