Electrical Supply| Power Supply: 115V, 60 Hz AC, Single Phase
Outlet Requirement: 3-Prong, GFCI
Circuit Protector: 15 AmpWARNING: 240 Volts AC may cause serious injury from electric
shock.
To reduce risk of injury:
1. Disconnect electrical power before servicing.
2. Only plug the unit into a grounded electric circuit.
3. Do not use an extension cord.
4. Do not use a plug adapter.
Principle of Operation| The Guardian Series Dehumidifiers utilize its integral
humidistat to monitor the conditioned space. When the relative
humidity goes above the selected setpoint, the dehumidifier will
energize air is drawn across an evaporator coil, which is cooler
than the dew point of the air. This means moisture will condense
out of the air. The air is then reheated through the condenser coil
and distributed back into the room.
Installation| The area to be controlled should be sealed with a vapor
barrier. If the unit is installed in a crawlspace, all vents should
be sealed.WARNING: Do not install your dehumidifier in a corrosive
environment. Some liquid vapor barriers dry via solvent
evaporation. Always make sure that the barrier is completely dry
and the area is thoroughly ventilated.

Product Usage Instructions

Step #1: Place dehumidifier on a level surface. Do not place the unit directly on the vapor barrier. For example, use blocks or pavers to create a level surface. If the unit is handled in such a manner that the compressor did not remain in the upright position, you will need to place it on a level surface, then wait a minimum of 2 hours before turning on.
Step #2: Set Up Drain Line. The included drain line attaches to the unit via a compression type fitting on the discharge end of the unit. To attach drain line, remove the compression nut and slide it over the end of the hose to be attached to unit. Slide compression nut side of hose over the insert on the compression fitting completely. Tighten compression nut.
Step #3: Plug unit into 15 amp grounded circuit.
