Water Wizard™ Installation

3. Wire the Solenoid(s)

Wire the supply line solenoid and drain solenoid as shown on the unit’s wiring diagram in the control center.

4. Wire the Temperature Sensor

If the evaporative cooler shipped separate from the unit, the temperature sensor must be wired. The sensor wire is bundled inside the discharge end of the evaporative cooler. Wire the sensor wire to terminals AI2 and AIC on the terminal strip in the unit’s control center.

Note

The Water Wizard™ start-up must be completed for proper performance.

Installation - Direct Expansion (DX) Coil Piping (optional)

Important

Guidelines for the installation of direct expansion cooling coils have been provided to ensure proper performance and longevity of the coils. These are general guidelines that may have to be tailored to meet the specific requirements of any one job. As always, a qualified party or individual should perform the installation and maintenance of any coil. Protective equipment such as safety glasses, steel toe boots and gloves are recommended during the installation and maintenance of the coil.

Important

All field-brazing and welding should be performed using high quality materials and an inert gas purge (such as nitrogen) to reduce oxidation of the internal surface of the coil.

Important

All field-piping must be self-supporting and flexible enough to allow for the thermal expansion of the coil.

1.Locate the Distributor(s) by Removing the Distributor Access Panel

2. Verify Nozzle Placement

Inspect the refrigerant distributor and verify that the nozzle is in place. The nozzle is generally held in place by a retaining ring or is an integral part of the distributor itself.
