WARNING
ELECTRICAL SHOCK HAZARD: 115-volts may cause serious injury or death from
electrical shock. Disconnect and tag electrical service before starting installation or
field-service. Leave electrical service disconnected until installation or field-service
is complete.
ELECTRICAL SHOCK HAZARD: An interrupted or broken ground may cause property
damage, serious injury or death should an electrical fault occur. The cabinet must
be grounded in accordance with NEC ANSI/NFPA 70-2011 or local codes. In Canada,
refer to Canadian Electrical Code CSA C22.1.
FIRE HAZARD: Use of improper wire may cause serious injury, property damage or
death due to fire. Do not use aluminum wire for electrical service to the dehumidifier.
Use only copper wire.

Use of an undersized circuit
breaker may cause property

The Model 1830 dehumidifier can be modified for applications where hard wire power to 115VAC is required; the Model 1850W must be hard
wired. An electrical disconnect switch can be installed as needed to comply with appropriate codes or ordinances. The ON/OFF switch on the
dehumidifier interrupts the 115VAC service to the internal components of the dehumidifier, but does not disconnect the power supply at the
115VAC terminals on the dehumidifier.
