CLEANING CONDENSER COIL
CAUTION: Circulating air, required to pass through and cool the condenser coil, is drawn
in at the bottom and is exhausted out through the top of the Unit. Failure to clean the
condenser coil will cause the refrigeration system to overheat.
1. Disconnect electrical power to the Cooling Unit at the disconnect switch.
2. Clean bottom side of the condenser coil using a vacuum cleaner, whisk broom, or soft-bristle brush to
remove any debris from the coil.
3. Check and make sure the fan blade moves freely and is not touching any surfaces, are not bent, or out of
balance. Check and make sure the wire guard is properly installed and is securely fastened.
4. Check and make sure the roof area immediately surrounding the Unit is free and clear of any debris that
may have collected such as leaves, paper,trash, etc.
5. Restore electrical power to the Cooling Unit at the disconnect switch.
ADJUSTMENTS
NOTE: To readjust the CO
2
regulator to a lower setting loosen the adjusting screw lock nut, then turn
the screw to the left (counterclockwise) until the pressure gage reads 5-psi lower than the new setting
will be. Turn the adjusting screw to the right (clockwise) until the gage registers new setting, then
tighten the lock nut.
