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 SqFt 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 DegF)
must
be installed
Offices and Commercial Spaces, Churches etc
These require ballpark sizing of approximately 12,000 Btu/h Capacity per 400 SqFt of room size
The units could have the possibility of providing cooling with ambient's below 65 DegF, 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 SqFt of room size
Low Ambient is typically not needed, unless a home office application is required.
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
25 DegF.
Installation
Determine the best location for mounting the Indoor unit, it must be located a minimum of 4 ft from the floor
Pay attention to the air circulation in the room, 9 & 12k units throw air 15ft, 18 & 24k units throw air 25ft, ensure
no obstacles to airflow exist
Locate the Indoor and Outdoor units as close together as possible, maximum line set run and lift
CANNOT
BE EXCEEDED
, then determine how the Interconnect piping, wiring and condensate hose is to be run
