Operation Maintenance Schedule
The following list is IMPORTANT to the proper function and long life of the unit.
Every Week
Check for Alarms
· Check that the red alarm light is not activated. If the alarm light comes on at any time, call a service
technician.
Check Room Temperature and Relative Humidity
· Check that the room temperature and relative humidity are within acceptable limits.
Every Month
Check the Air Filters
For units equipped with Dirty Filter alarm, change filters immediately upon alarm, then reset.
· All units have return air filters. The unit cannot work properly with dirty filters.
· All dirty filters should be replaced with identical new filters.
· Do not operate the unit for any amount of time without all filters in place.
Check the Humidifier
· Make sure the strainer is clean.
· If the High Water Sensor light on the humidifier is illuminated (except during startup, see Startup -
Humidifier ), the cylinder must be replaced. For replacement instructions , see Operation -
Maintenance - Humidifier.
Check that the condensate drain pan(s) is clean.
For units so equipped, check that the remote heat exchanger is clean.
Clean any trash or leaves that might interfere with proper airflow.
Check remote heat exchanger (if any) fan operation.
See Operation - Maintenance - Remote Heat Exchanger.
Every Six Months
For units with mechanical refrigeration, check that there are no bubbles in the sight glass after 10
minutes of compressor operation. See Startup - Adjustments .
Check the evaporator superheat. See Startup - TXV Adjustment .
With the unit disconnect switch open, check that all power connections and terminal screws are tight.
Refer to NEC 110.14 or other applicable codes.
Every Twelve Months
Check the condensate drain pan for any accumulated residue. Clean as necessary.
Check the air heat transfer coils for dirt and/or trash.
· If the coils are dirty
-- Clean the coils with a solution of mild soap in warm water. Do not use corrosive cleaning agents.
-- Increase the frequency of filter replacement. Dirty filters leak dirt onto the coils.
In the event of a future shutdown, leave power on the unit for the crankcase heaters if safe to do so. To
start the Ecosaire ® unit again, follow the steps in the STARTUP section of this manual.
