Supply water and drain overflow connections

Regardless of the type of water used, the following general

instructions MUST be followed:

• Make union connections at the humidifier on the make-up water

supply and drain/overflow lines.

• Provide a shutoff valve in the supply water line to isolate the

humidifier from the water system while servicing.

• Shock arrester, provided by installer, is recommended to reduce

water hammer.

• A 1" (25 mm) opening is provided in the humidifier tank to

accommodate skim and/or overflow protection. (Note: Follow

governing code requirements regarding size of drain pipe.)

• Use insulating unions or bushings to make connections between

copper and other dissimilar metal fittings, such as galvanized

steel. These insulating fittings are required to minimize

electrolytic corrosion, which results from the direct connection of

dissimilar metals in a water system.

• Before beginning ignition sequence of the humidifier at a new

installation, make sure the humidifier tank is full of water and the

water is free to flow into the tank.

• If planning to use heated supply water, disconnect the water

supply line to the water tempering device at the fill manifold

and reconnect it to a cold water supply. This will ensure that the

water tempering device operates properly.

Notes:

* In order to minimize DI/RO water use, disconnect factory piping to the water tempering device and pipe directly to tap water.

If planning to use heated supply water, disconnect the water line to the water tempering device at the ﬁll manifold, and reconnect it to a cold water supply.

This will ensure that the water tempering device operates properly.
