CAUTION
RISK OF PERSONAL INJURY
Cover all openings of the unit to prevent a hand or finger from access inside the unit.
Starting Up and Operating the HEPAir
Now that the installation is complete, it’s time to start the unit up. Check to make sure all
ductwork and electrical connections are secure.
Replace all panels that were removed during installation. Check that all of the openings in the
unit are covered with a blank a panel, ductwork connection or a grille.
Turn on the Unit
Plug in the unit. Turn-on the rocker switch on the side of the unit. The rocker switch lights up to
indicate power to the unit. The unit may not come on right away due to the timer built into the
circuiting to prevent short-cycling.
Running the Unit
✓
Check unit to confirm the compressor is running, such as the hum of the compressor
or cool air leaving the unit.
✓
Check for any unusual noise or vibration, such as clanking or rubbing.
Initially, the unit may run continuously for several hours, up to a day or more, while it lowers
the space temperature.
Setting the Thermostat
Follow the instructions shipped with your thermostat, or with the remote PID controller.
Regulating the Space to be Conditioned Temperature
The space to be conditioned may have a natural temperature gradient of approximately 5 to 10
degrees F (-15 to -12 Deg C) between floor and ceiling. To increase or decrease the temperature
in various zones, change the air flow patterns.
To keep the entire space at the same temperature, set the thermostat to run the supply fan
continuously and not just when the cooling is operating. Set Fan switch to ON instead of AUTO.
NOTE: To monitor the space temperature, place thermometers in various locations in
the space to monitor the temperature zones. Change the temperature in various zones
by shifting the air flow patterns.
Changing the Air Flow Direction
The grilles furnished with HEPAir are single directional. Rotate the grilles to change the
direction of the air flow.
When using multiple supply ductwork, balance the air flow between the ductwork. If too much
air flows though one duct but not enough air flows from the other duct, install a damper or other
restriction into the duct with too much air. That will force more air to flow out the other duct.
