SETTING UP THE DEHUMIDIFIER
WARNING
No not obstruct the air intake or air outlet
IMPORTANT
Place dehumidifier in the upright position. When
transporting a dehumidifier to site, allow the
dehumidifier to stand for 30 minutes before switching
ON. This is necessary to allow the refrigerant system to
stabilize and avoid system damage.
PLACE IN ENCLOSED AREA: For best results,
operate the dehumidifier in an enclosed area to create
a "drying chamber." Close all doors and windows that
open to external areas to maximize the dehumidifier’s
water removal efficiency. Keep traffic through the
drying chamber to a minimum. Place the dehumidifier
in the center of the room away from walls and
furnishings where airflow may be obstructed.

Illustration of correct positioning for best performance
PROPER AIR FLOW IS ESSENTIAL: Do not place
this dehumidifier in a position where the front Air
Intake Grill or rear Air Outlet is blocked by walls,
furniture or any other obstruction. Do not attach
ductwork to the unit as air flow restrictions will result.
ENSURE PROPER DRAINAGE: This dehumidifier
contains a built-in pump that connects to a drainage
hose which is stored in the back of the unit. Uncoil the
entire hose to ensure that there are no kinks or
restrictions and place the unattached end into a drain
or run to the outdoors. Ensure that water piped to the
outdoors does not create a slipping hazard. To avoid
damaging or overworking the pump, do not exceed a
3m vertical lift height between the pump and drain.
KEEP CLEAR
Do not attach ductwork
or duct air outside of
drying chamber.
