3.3 Plumbing
3.3.1 Water supply
The compactSteam must be supplied with water (not softened or demineralized) having the following characteristics:
Fig. 3.g
The water feed line should be 1/2” copper, PVC or poly tubing run to within 3 feet of the humidifier, then bushed down to 1/4” O.D. poly to make the final connection
to the 1/4” O.D. compression fitting supplied with the unit. WARNING: WE RECOMMEND TO USE A SOFT POLY HOSE TO ABSORB THE WATER HAMMERING
IN ORDER TO AVOID DAMAGES TO THE FILL VALVE. With poly tubing an insert should be used to support the tubing and prevent leaks. The fitting then threads
onto the fill valve inlet located on the bottom of the humidifier. Note that there is a strainer built into the fill valve fitting underneath the unit, which will require periodic
cleaning, so be sure to allow clearance for access.
NOTE: softened water should NOT be used as it is generally corrossive to the electrode plating.
3.3.2 Water drain
The compactSteam also requires connection to a drain. The drain water characteristics are:
Fig. 3.h
The drain line can be 1-1/4” schedule 40 PVC or CPVC, 1-1/4” copper, or 1-1/4” Polypropylene. In all cases, the drain tube is slipped over the drain outlet on the
bottom of the humidifier. It is not glued or otherwise attached to the humidifier, so it must be supported by itself.
If 1-1/4” schedule 40 PVC or CPVC is used, then a coupling should be used between the drain line and unit drain.
The
compactSteam includes a drain tempering valve that opens whenever the drain valve opens and flushes cool feed water into the drain line to insure that the
drain water temperature never exceeds 140 °F / 60 °C.
NOTE: Drain line must be trapped under the unit to prevent flash steam from condensing in the unit cabinet.
