Series GEN 2 Ultrasonic Humidifier IOM Manual
Supply and Drain Piping
The Ultrasonic Humidifier will require a field -installed water supply line and overflow drain line. Refer to the
piping diagram provided with your unit for details. For the water supply, use DI or RO water.
The water supply to the humidifier cannot be taken directly from the public water service. Untreated supply
water will leave a residue in the conditioned space where white powder that is dissolved in the water is
produced after evaporation from the calcium or magnesium.
In cases where water quality, especially residue from evaporation,
pH, total hardness and water
conductivity exceeds or is outside the range of standard, routine maintenance intervals to ensure
continuous operation will be more frequent than usual. Also, the operating life of the transducers and print
plates will be significantly reduced.
Figure 7. Water Supply and Drain
CAUTION
It is essential that DI or RO water be used as the supply water source to maintain warranty coverage. The
use of untreated water will void the warranty.
NOTE
: The water supply piping must be noncorrosive stainless steel or poly tubing rated for use with
deionized water.
Prepare the water supply piping. The water supply piping should be equipped with a water supply valve for
maintenance purposes (user provided) at a place as close as possible to the humidifier. The valve must
be rated for use with DI water.
After the water supply valve is installed, flushing should be done by supplying water (see Purge the Water
Line). This is a necessary step to prevent chips and oil in the piping from entering the humidifier.
Connect the water supply piping to the humidifier by means of a ¼” stainless steel or poly tubing (user
provided). A strainer or fl ow regulator is preassembled to the water inlet in the back of the humidifier.
The strainer or fl ow regulator is equipped with a ¼” push-to-connect, swivel 90° fi tting (see Figure 6). If there
is a risk that the water supply piping could freeze, wrap the piping with insulating material.
A drain line rated for use with DI water must be provided from the I/8” MPT water tank drain stub in the rear
of the unit. Connect the drain line to the stub so that overflowing water can be directed into a drain pan or
an appropriate place (such as an open building drain).
The drain line must meet local and national plumbing codes, be sloped downward and away from the
