COOL/HEAT mode to
FAN mode
The indoor unit makes
noises A squeaking sound may occur after running the unit in HEAT mode due to expansion
and contraction of the unit’s plastic parts.
Both the indoor unit
and outdoor unit make
noises
Low hissing sound during operation: This is normal and is caused by refrigerant gas
flowing through both indoor and outdoor units.
Low hissing sound when the system starts, has just stopped running, or is defrosting:
This noise is normal and is caused by the refrigerant gas stopping or changing direction.
Squeaking sound: Normal expansion and contraction of plastic and metal parts
caused by temperature changes during operation can cause squeaking noises.
Cooling and Heating Models: If the Operation light and PRE-DEF (Pre-heating/
Defrost) indicators are lit up, the outdoor temperature is too cold and the unit’s
anti-cold fan is activated in order to defrost the unit.
In Cooling-only Models: If the “Fan Only” indicator is lit up, the outdoor
temperature is too cold and the unit’s anti-freeze protection is activated in order
to defrost the unit.

DUCT CONNECTIONSAir supply and return may be handled in one of several ways best suited to
the installation (See table for dimensions for duct inlet and outlet connections). The vast majority of
problems encountered with combination cooling systems can be linked to improperly designed or
installed duct systems, it is therefore highly important to the success of an installation that the
duct system be properly designed and installed. Use flexible duct collars to minimize the transmission
of vibration/noise into the conditioned space. Where return air duct is short, or where sound is
liable to be a problem, sound absorbing glass fiber should be used inside the duct. Insulation of duct
work is a must where it runs through an uncooled space during the cooling season. The use of a vapor
barrier is recommended to prevent absorption of moisture from the surrounding air into the insulation.
The supply air duct should be properly sized by use of a transition to match unit opening. All ducts
should be suspended using flexible hangers and never fastened directly to the structure. This unit
is not designed for nonducted (freeblow) applications. Duct work should be fabricated and
installed in accordance with local and/or national switchs.
