ELECTRICAL

CAUTION

Wiring to be performed by a licensed electrician.

This unit must be installed on a GFI Circuit.

CAUTION

Equipment Damage Hazard

Failure to wire the humidifier in accordance with the

wiring instructions could cause permanent damage.

Such errors will void the warranty.

Installation Steps

Unit requires a dedicated circuit with GFI protection.

Bring circuit to a disconnect near the device to protect

from electrical shock when servicing.

Hard wire humidifier to disconnect according as shown

at right.

Install factory-supplied jumper between the P terminal

and the terminal that corresponds to supply voltage.

Remove green wire attached to case body and drain

valve (remove canister for access).

Clip ground wire as close to drain valve as possible and

remove excess.

Fig. 15. Primary power connection.

NOTES:

—

Honeywell requires the use of a GFI circuit on this device to protect the homeowner from electrical shock.

—

When installed correctly, the green wire should be removed from the drain valve. The green wire comes pre-installed

from the factory to protect the homeowner in case of an improper installation or when it is not possible to retrofit a GFI

circuit. See Fig. 23 for the location of green wire on the drain valve.

—

Ensure that adequate power is available to carry full humidifier amp draw as indicated on the specification label.

—

Do not use neutral wire as a ground; connect a dedicated ground to ground termination.

—

All wiring to be in accordance with national and local electrical codes.
