Installer Supplied Items

The following Items are necessary for the installation of the unit. An Installation Kit can be purchased that in cludes these Items.
Refrigerant Line Set: Flare Connection only, suitable for R410A with both lines insulated, max length 50ft.
High Voltage Interconnect wiring: 14 AWG wiring from Outdoor unit to Indoor unit for Power and Control.
Condensate tubing: Per local codes to remove condensate from the indoor unit.
The following Items are necessary for installation but are NOT included in the Installation Kit.

Main System Breaker: Sized per unit requirements, to be mounted adjacent to Outdoor unit.
Refrigerant: R410A required for additional line set charge.
Mounting Hardware: Wall Anchors, Condenser Pad etc.

Items for Consideration

Application

Check the application of the unit prior to installation, certain applications require additional components or installation
parameters.

Computer or Data Server Rooms

These require ballpark sizing of approximately 12,000 Btu/h Capacity per 250 Sq Ft of room size.
The units will be running 24/7, so a Low Ambient Head Pressure Controller (See accessories), a Crankcase Heater and
possibly a Wind Baffle (Field Supplied for cooling below 32°F) must be installed.

Offices and Commercial Spaces, Churches etc

These require ballpark sizing of approximately 12,000 Btu/h Capacity per 400 Sq Ft of room size. The units could have the
possibility of providing cooling with ambient temperatures below 65°F, so a Low Ambient Head Pressure Controller (See
accessories) is required as is a Crankcase Heater (field supplied).

Residential, Bedrooms, Family Rooms etc

These require ballpark sizing of approximately 12,000 Btu/h capacity' per 600 Sq Ft of room size. Low Ambient controllers
typically are not needed, unless a home office application is required.

NOTICE:

Heat Pumps are a great application, however the units do not feature any back up resistance heat, so we do not recommend
their use as a primary source of heat in areas where the winter temperatures fall below 30°F.

Installation

Determine the best location for mounting the Indoor unit. It must be located a minimum of 4 ft from the floor. Paying close
attention to the air circulation in the room, 9,000 &12,000 BTU units throw air approximately 15ft, 18,000 & 24,000 BTU units
throw air approximately 25ft. Ensure no obstacles to airflow exist.

Locate the Indoor and Outdoor units as close together as possible, maximum line set run in cannot BE EXCEEDED, then
determine how the Interconnect piping, wiring and condensate hose is to be ru n.

temperature sensor mounted on the unit then controls the unit operation.
Several modes of operation are available to the end user depending on the type of comfort required. AII unit operating functions
are controlled via the remote controller.

Optional Controls and Components
Low Ambient Controller: ICM 326H must be used in Data Room or Commercial applications

For a wiring diagram please follow general diagram supplied with ICM Controller. Probe must be located in the fin pack or on a
return bend that measures approx 100°F during normal operation.

Condensate Pump: Field Installed Aspen brand of Condensate Pump (model ASP-MO-115)

Follow their wiring diagram recommendations. This pump is installed externally to the unit.

UNIT INSTALLATION

Follow Instructions, failure to follow instructions may cause possible malfunction and void any warranty.

Step 1

Remove Indoor and Outdoor units from the carton/box
