3 Start-Up Procedures
Read this section thoroughly before attempting to commission the Desert Aire dehumidifier.
A complete start-up will minimize operational problems and expensive callbacks. The start-up will be
quicker and easier if there is a heat and humidity load present in the space. Energize any auxiliary
heaters before start-up so that the air is at the design temperature.
3.1 Preliminary Inspection
Verify that all contractors have completed their work. Find the Desert Aire “LW Start-Up Report,”
which is normally placed inside this manual within the electrical compartment of the dehumidifier.
You must fill out the start-up report to validate the dehumidifier warranty. Check the following items:
• Before starting unit, remove wooden shipping blocks found beneath compressor(s).
• Before starting unit, remove shipping restraining brackets on supply blower equipped
with a spring isolation base, if applicable.
• Make sure that the unit is level and securely mounted so that it cannot shift or
transmit vibration to the building.
• Verify that the incoming power supply matches the rating plate of the dehumidifier.
The available power supply voltage must be within ±5% of the voltage printed on the
rating plate.
• With the power supply disconnected and locked, tighten all field and factory electrical
connections.
• Check and adjust the belt tension for proper deflection at the mid-point of the blower
belt(s). See Figure 10.
• The deflection is based on the belt length. The belt length can be found on the belt
itself. Determine the force using the Belt Deflection table in Figure 11.
• Inspect the air filters and coils to assure they are clean. If necessary, clean the
coils and install new filters.
• Check the field and factory piping for leaks. The internal piping may have been
damaged during shipping.
• Purge any air, dirt, or debris from water lines (if used) to avoid clogging the
internal passages of optional heating coils.
• Check the drain pan and the condensate piping. Test the drain and prime the ptrap
by pouring water into the drain pan or water side heat exchangers.
• Verify that all service valves in the refrigeration lines are fully open.
• If you installed a supplemental air heater, make sure you installed it in the air
discharge (or “supply”) duct and not the return duct.
• If your dehumidifier has a water heating condenser, turn on the circulating pump to
run water through the system. Inspect the piping and repair any water leaks you find.
• After the remote condenser has been installed, enable its operation through the
CM3540 Controller.
