The above is not true for a heating coil; most heating coils are not designed to be wetted. If
installing upstream of a heating coil a mist eliminator must be used.

Pump Module

The pump module location should be selected with the following guidelines in mind:

Available Power: The pump should be located close to its supply power source.

Available Water: The pump should be located close to its RO or DI water source.

Proximity to Manifolds: The pump should be located as close as possible to the manifolds to
minimize pressure losses in the lines. See Table 4 Piping Pressure Losses for more information.

Available Drain: To prevent damage to other equipment in the event that the pump module
should leak, it is recommended that the pump module be located near a floor drain.

Proper Ventilation: The pump will generate heat during operation. Covered pump modules
include cooling fans, while uncovered pump modules typically rely on natural airflow in the room
for cooling. Ensure that the pump module is located in an area where it can receive a
reasonable amount of airflow. Avoid installing other equipment on top of or in front of the pump
module.

Occupants: The pump will generate some noise and vibration during operation. The pump
should be located somewhere in a place noise and vibrations will not disturb occupants of the
building. Installing the pump module on vibration isolators is recommended to minimize
vibrations. Optional pump covers are available for large pump skids to minimize noise.

Installing the Pump

Move the pump to the location selected and secure it to the floor.

Confirm that primary power source matches the specification label on the pump. It is strongly
recommended that the pump module have a dedicated power supply to prevent brownouts
when the pump module starts. Install a manual disconnect switch for the pump module.

Install connection to the reverse osmosis / de-ionized water supply. Ensure that supply water
pressure from the RO or DI water system is at least 25 psi (1.7 bar) at the inlet to the pump
skid. Never exceed 60 psig inlet pressure (Danfoss Stainless Steel Pump) or 90 psig (Giant
Brass Pumps). The water system capacity must be a minimum of 120% of the humidification
system capacity.

Running the pump on any voltage other than what is listed on the spec label can
serious equipment damage and may ignite a fire.
