NOTE: Failure to follow the following seasonal shut down procedures may result in reduced performance to the heat
exchangers and may cause equipment damage.
1. Inspect the unit to make sure that all safety devices and other parts are secure.
2. Turn the manual water supply valve off upstream of the pressure regulator/solenoid valve assembly.
3. Open the water supply line drain valve at the Tee and drain off water in line.
4. Close the supply duct dampers and/or install off-season duct blocking devices.
5. Leave the exhaust louvers open so the unit will dry out.
6. Close off the building barometric damper for the winter according to the manufacturer’s instructions.

Seasonal Start-Up Procedure
1. Inspect the unit to make sure that all safety devices and other parts are secure.
2. Install new water filter cartridge, (minimum of 30 micron).
3. If needed vacuum out intake air plenum.
4. Check the level of surfactant in the wetting system. Top off the reservoir with Dawn™ or Palmolive™ dishwashing
detergent, if necessary.
5. Install new air filters.
6. Check that the unit’s fan will free spin by turning by hand.
7. Turn on the supply water and verify there are no leaks. Water pressure must be between 25 and 80 psi dynamic pressure
(172 and 552 kPa), when the water is running.
8. Open the cooled air-supply (or conditioned air) damper and/or remove any air blocks that were used to winterize the air
conditioner.
