INSTALLER'S GUIDE
DIRECTION FOR CHARGE ASSIST™
Be sure to set Dip Switches for Line Length and Lift before
entering Charge Assist™ Mode. (See Table 2 Subcool Charging
Table Corrections for Line Length and Rise on page 6.)
To enter Charge Assist™ Mode, press the MODE button for at
least one second. The on-board LEDs will indicate if the system
is capable of continuing. For a detailed description of on-board
LEDs and their function, see the Charge Assist™ Procedure
(18-AC72D1-1) contained in the Outdoor Unit.
The system will take approximately 12-20 minutes to stabilize
before the charge can be checked by Charge Assist™. Once the
system is stabilized, watch to see which LED turns on next. If
the system charge is correct, the “CHARGED” LED will turn on
and remain on for one hour. Once charged, the system will exit
Charge Assist™ and control will return to the Comfort Control.
If the system charge is low, the “ADD” LED will turn on and stay
on up to one hour or until enough refrigerant is added to reach
the required system charge level and turn on the “CHARGED”
LED.
When the “ADD” LED is on, the charging solenoid output will be
active. This feature works to automatically control refrigerant
flow with BAYCAKT001.
If the system charge is high, the “REC” LED will turn on and the
unit will exit Charge Assist™. You must recover refrigerant
from the system before re-entering Charge Assist™.
