COIL CLEANING
If the coil needs to be cleaned, it should be cleaned with water.
As an alternative to water, EVAP-Green by Nu-Calgon is the only pH
neutral coil cleaner approved to be used when it is properly diluted.
ENSURE THE CLEANED COILS ARE THOROUGHLY RINSED
AFTER USE OF EVAP-GREEN.
SECTION IX: INSTRUCTING THE OWNER
Assist the owner with registering the unit warranty using the warranty
card included with the unit, or preferably online at
www.upgproductregistration.com
. It is strongly recommended to
complete a startup sheet showing the critical readings of the unit at the
time of commissioning, which can be uploaded as part of the online
registration process.
SECTION X: AIR SYSTEM ADJUSTMENT
Refer to furnace or modular air handler instructions.
