DO NOT pull the drainpipe forcefully. This
could disconnect it.
The drainpipe is used to drain water away from
the unit. Improper installaon may cause unit
and property damage.
CAUTION
•
Insulate all piping to prevent condensaon,
which could lead to water damage.
• If the drainpipe is bent or installed incorrectly,
water may leak and cause awater-level switch
malfuncon.
• In HEAT mode, the outdoor unit willdischarge
water. Ensure that the drain hoseis placed in
an appropriate area to avoidwater damage
and slippage.

NOTE ON PURCHASING PIPES
Installaon requires a polyethylene tube
(Internally threaded tube 3/4 inch), which can
be obtained at your local hardware store or
dealer.

Cover the drainpipe with heat insulaon to
prevent condensaon and leakage.
VERTICAL DISCHARGE
PRIMARY DRAIN
These units operate with a posive pressure at
the drain connecons and a drain trap is required.
The trap needs to be installed as close to the unit
as possible. Make sure the top of the trap is below
the connecon to the drain pan to allow complete
drainage of the pan.

IMPORTANT
Aer removal of drain pan plug(s), check
drain hole(s) to verify that drain opening is
fully open and free of any debris. Also check
to make sure that no debris has fallen into
the drain pan during installaon that may
plug up the drain opening.
Seal around the exing drain pipe, liquid
and sucon lines to prevent infiltraon of
humid air.
On units of this type, where the blower
“draws” rather than “blows” air through the
coil, traps must be installed in the condensate
drain lines (primary and auxiliary, if used).
Traps prevent the blower from drawing air
through the drain lines into the air supply.
