DH 70
Read the installation operation and maintenance instructions carefully before installing and using this unit.
Proper adherence to these instructions is essential to obtain maximum benefit from the DH70 system.
Installation contrary to these guidelines or lack required maintenance will void warranty.
Unit Location
The DH70 can be installed in a variety of locations to meet the
owner’s needs as listed below. In all cases keep the following
cautions in mind:
• The unit is designed to be installed indoors in a space that is
protected from rain, flooding and/or other forms of excess water.
Unit is not designed to be exposed to chlorinated pool conditions
or spaces where unit will be exposed to corrosive chemicals or
conditions.
Install the unit with space to access the front panel for
maintenance and service. Also allow easy access to the filter
cover panel.
DO NOT INSTALL THE UNIT WITH THE FRONT
PANEL OR FILTER COVER PANEL INACCESSIBLE.
• Avoid discharging the air directly at people, over the water in pool
areas, or other areas or objects where dehydration or evaporation
of moisture is not desired.
• If used near wet areas, be certain there is NO chance the unit could fall into the water or be splashed and that it is
wired into a GROUND FAULT INTERRUPTER protected circuit (see local codes for other requirements).
• A secondary drain pan
MUST be placed under the unit if installed above a living area or above an area where water
leakage could cause damage (see local codes for other requirements).
• DO NOT locate the DH70 directly on structural members where noise or vibration may be objectionable. The DH70
is equipped with adjustable support feet to raise and level the unit from the mounting surface, these adjustable feet
should be utilized to provide improved drainage from the drain pan and should be adjusted to tilt slightly toward the
drain utilized.
