Section V: Operation
PURGE MODE CONTROL MENU
!
CAUTION
It is the user’s responsibility to use this feature properly to prevent freeze damage to downstream equip-
ment. 100% outside air at below freezing conditions has the potential to cause serious damage.
Purge Mode causes the unit to force the optional, field-provided, economizer dampers and fan to full open, introducing
large quantities of outside air to the space. This is typically used when “shocking” the pool. Compressor operation is
disabled during purge, but the auxiliary air and water heating systems remain active.
If the unit is not equipped with the economizer option, a flashing
“CAUTION!!! NO FREEZE PROTECTION”
warning will be displayed. This warning indicates that operation of purge mode, without regard for outside air
temperatures below freezing, can result in damage to hot water coils or other equipment in the pool area.
