Maintenance

Internal Protections

Internal protections operate if an internal fault occurs in the unit.

Note:

If the heat pump is operating in Heat mode, a defrost cycle is activated to remove frost from an outdoor unit that may 

have accumulated at low temperatures. The internal fan is switched off automatically and restarted only after the defrost 

cycle is completed.

Operating Ranges

For efficient use, operate the unit within the ranges shown in this table.

Operating Mode for Heat Pump Systems

For heat pump systems, the main indoor unit controls whether the system operates in heating or
cooling. If the main indoor unit calls for heating and sub-indoor units calls for cooling, the main
indoor unit (and any other sub-indoor units that call for heating) will operate in heating mode, and
the sub-indoor units that call for cooling will do nothing.

Maintenance

Cleaning the Exterior

Use a dry or damp cloth to wipe the surface of the unit as needed. If necessary, use mild soap and
water on a damp cloth. Use a soft brush to remove dirt from the grille.

Type

Description

Cold air dump

The internal fan will be off to prevent a cold air dump when the heat pump is in defrost mode.

Defrost cycle

The internal fan will be off to prevent a cold air dump when the heat pump is in defrost mode.

Anti-short cycle timer

The compressor observes a 3-minute off time when cycling power to the unit or after an 
outage.

Note:

The standard temperature for heating is 45˚F (7˚C). If the outdoor temperature drops to 32˚F (0˚C) or below, the 

heating capacity can be reduced depending on the temperature condition. If the indoor cooling temperature is set higher 

than 90˚F (32˚C), the unit will not cool to its full capacity.

NOTICE

Avoid equipment damage and risk of fire!

Avoid using benzene or other flammable solvents. They may damage the surface of the unit

and increase the potential for fire.
