Step 5
Once the system has stabilized, Charge Assist
TM
will
do one of the following:
Step 1
Hook-up the solenoid to the refrigerant bottle and the
Charge Assist
TM
port (Figure 24).
IMPORTANT: Purge refrigerant lines during hook-up.
Once purge is complete, be certain to return the purge
knob on solenoid to the OFF position (Figure 25)!
Step 2
Plug in the solenoid to the Charge Assist
TM
control
board (Figure 26).
Step 3
Start Charge Assist
TM
by pressing the MODE button
for a minimum of 2 seconds (Figure 27).
Step 4
The system may need to run up to 20 minutes to sta-
bilize.
Note: During system stabilization, the STABILIZING LED will
flash.
Note: If the system has been running, it may go straight to Step
4.
Note: For communicating systems that have not been running,
the low stage compressor will run for one minute and then turn
off. After one minute (inter-stage delay), the high stage com-
pressor will start and the stabilization routine will begin.
• If charge is required, the solenoid will automatically
open to add refrigerant to the system. Once properly
charged the solenoid will automatically close. The
CHARGED LED turns on (not flashing) and the ADD
LED is off.
• If the red REC LED is on - See “Adjusting System
Charge WITHOUT Charge Assist
TM
Tool
BAYCAKT001AA (Solenoid Kit)” - Step 4
• If the green CHARGED LED is on, Charge Assist
TM
has determined that the system is correctly charged.

Note: Charging set-up should be for liquid refrigerant. Picture shows
inverted bottle, not all bottles need to be inverted. Some cylinders must
be inverted for liquid and others contain a dip tube for liquid refrigerant.
This feature requires liquid charging. Determine how to position the bottle.
