NOTE: Improper wiring could damage the blower pack or RESDELUX PCB.

9.Remove the front door and service cover from the RESDELUX humidifier.

10.Connect the power leads for the blower pack to terminal P7 on the RESDELUX control board located next to the capacity adjustment potentiometer.

11.Replace the electrical service cover and front door.

Once the power is restored the RESDELUX humidifier is ready for service.

PLUMBING

For humidifiers installed in some cities including the City of Los Angeles:

A city-approved spring-loaded double ball CHECK VALVE must be supplied and installed by contractor on each of the potable water inlets to each humidifier. Recommended valve manufacturer: Watts Regulator phone number 508-688-1811. Size: Depending on supply line 1/4", 3/8" or ½" NPT inlet and outlet. Model: #7.

All water supply and drain line connections should be installed in accordance with local plumbing codes.

WATER SUPPLY LINE

1.The Humidifier is intended to operate on potable (cold) tap water.

2.If the raw water is very hard, NORTEC can provide longer cylinder life on softened water; however, softened water is more conductive and

more corrosive. Some hardware changes may be required, at the time of order or in the field.

3.DO NOT supply hot water to the humidifier. Minerals will adhere more easily to surfaces and the fill valve’s small flow regulating orifice could become plugged.

4.ALWAYS supply and install a shut off valve in the water supply line dedicated to the humidifier to facilitate servicing. Use ½" O.D. copper to within 4 feet of the humidifier. Reduce copper to 1/4" O.D. and connect to the factory-supplied 1/4" olive compression fitting under the humidifier.

DRAIN LINE

1.The humidifier is equipped with a 7/8" O.D. unthreaded horizontal drain outlet from the drain canal on the bottom of the humidifier. A field-supplied funnel or reducer(see Figure #11) is recommended. It will prevent backup in the drain pan and in the cylinder due to partially blocked or poorly installed drain lines.

2.The drain line should not drain into a sink used frequently by personnel, or where plumbing codes prohibit it. Route to a floor drain or equivalent for safety reasons, since drain water from humidifier can be very hot.

3.Keep drain lines as short as possible. Keep drain lines sloped down, not level and not up since low spots in drain lines will accumulate sediment and cause backup. The drain line should be 7/8" O.D. copper pipe or larger. Do not use plastic pipe for drain lines.

4.Each drain line from these humidifiers must be routed without dips or sags to terminate above
