Maintaining a Freeaire System

REGULAR MAINTENANCE

ALL Freeaire systems: ONCE A YEAR have a trained Freeaire technician review all the settings entered into the Cooler Controller. An incorrect setting can have major consequences in energy savings or proper performance. If experience has shown a default setting to be not desirable for a particular installation and it has had to be changed, the change should be noted in pencil on a sticker on the front of the Cooler Controller or in this book, kept with the controller. That way, the annual review of the settings will not cause them to be changed unnecessarily. Combine this controller check-up with annual condenser and evaporator coil cleaning as well as any outside air filter replacement. Restoring maximum airflow in all equipment leads to improved heat exchange and higher effficiency.

OUTSIDE AIR systems only: At least once a year, remove the filter from each filter housing and, if dirty, replace it with a new one. Contact your Freeaire dealer for replacement filters, or Go to Catalog of Options: Filter.

SUMMER PLUGS (These are an option that can be used with Freeaire Systems with Outside Air. Go to Catalog of Options: Summer Plugs.)
At the beginning of summer (around the last frost):
Insert the summer plugs in each of the exhaust and intake damper housings.
Switch OFF the OUTSIDE AIR SYSTEM at the Cooler Controller.
At the end of the summer (around the first frost):
Remove the summer plugs from all exhaust and intake damper housings.

Switch ON the OUTSIDE AIR SYSTEM at the Cooler Controller.
