Heat Controller

Installation Notices:

1. The unit must only be installed by authorized servicer and in compliance with this installation instruction.
2. Installation must be performed in accordance with the requirements of NEC or CEC and all local codes by authorized
personal only.
3. WARNING: Before obtaining access to terminals, all supply circuits must be disconnected.
4. Due to high temperature of the refrigerant circuit, please keep all conduit cables away from the copper tubes to prevent
melting the insulation.
Selecting installation place
Choose a location that places the outdoor unit as close to the indoor unit as possible. The maximum unit separation and
vertical lift (compressor above the evaporator) must be taking into account. Do not exceed allowable refrigerant line lengths.
Indoor unit
• Unit must be installed in a location that does not obstruct the flow of air and ensures clearances are maintained. (see
installation drawing)
• The site must support the weight of the unit.
• The site must be easily accessible for cleaning, replacement of the air filter, maintenance and service.
• The indoor unit should be mounted as high up on the wall toward the ceiling, leaving a minimum of 6" (150mm) of space
between the ceiling and the top of the indoor unit. (see installation drawing)
• Due to the possibility of electronic interference with other devices, it is recommended that there should be at least
3 ft (1 meter) between the unit and other devices/appliances, such as televisions or radios.
• The unit should be installed away from possible exposure to fire, smoke, of flammable gases and be protected from
direct sunlight (sunlight can interfere with the signal between the unit and the remote control).
