INSTALLATION
8.
When this portable air conditioner operates in the cool mode, fresh outdoor air
must be directed into the unit and hot air must be exhausted out of the room to
complete heat exchange of the condenser. When the unit operates in FAN or
HEAT mode, no outdoor air is used hence it is not necessary to complete
window kit installation.
Installation Kit:
Air Inlet & Air Outlet Hose (2 sets) Telescoping Window Panel Kit
Unit with Hoses Attached Cover the Exhaust Port When Unit Not in Use
There are two exhaust ports at the back of the unit. Cover the exhaust ports
when unit is not in use. To ready unit for installation, remove the exhaust port
cover by turning in a counter-clockwise direction.

1. Measure the window the unit will be installed into and adjust the telescoping
Window Panels to fit into the window. If window is either too wide or too
tall, fill the remaining space with foam or other appropriate material. Make
sure that the holes on the Window Panel are exposed for connection of
Window Kit Adaptor.
2. Screw the hose clockwise into the Terminal End, and the other end of the
hose to the Window Kit Adaptor. Apply same procedures to both air inlet
hose and air outlet hose.
3. Secure the Terminal End to the Exhaust Port. Apply same procedures to
both air inlet hose and air outlet hose.
4. Connect the Window Kit Adaptor to each of the holes on the Window Panel.

DRAIN EXCESS CONDENSATE WATER
10.
Condensate Disposal:
Drain Water from Upper Drain Port:
Procedures: Connect the Water Drain House to the Upper Drain Port
allowing water to flow to a water bucket. (See above illustration).
Remember to reinstall the cap on Upper Drain Port after draining water. The
Upper Drain Port can be used if a floor drain or some other means of
disposing of condensate is not available.
Drain Water from Lower Drain Port: (Before Long Term Storage Only)
Procedures: Remove the Rubber Drain Plug on Lower Drain Port.
Connect the Water Drain Hose to allow water to drain to a floor drain or other
water outlet. Remember to reinstall the Rubber Drain Plug after draining
water.
Under normal operating conditions, this unit is designed to dispose of
condensate collected via an internal system that pumps water onto the hot
condenser coil for re-evaporation. It is then expelled to the outdoors via the
air outlet hose. If the unit is operated for prolonged periods during very high
humidity conditions, this system may become overwhelmed and the unit will
shut off. Excess water must be drained from the unit before it will restart.
