Option 6: Tank Refill - yellow jacket 3788 Series Operation Manual

TANK REFILL
In order to use the charging mode, you must have
at least ten (10) pounds of refrigerant in the storage
tank. Follow this procedure to add refrigerant to the
storage tank. When adding R-134a to the onboard
storage tank you will need to use the tank refill
adapter (PART NUMBER 19153) supplied in the
accessory kit. This adapter connects the low side
auto service coupler to the tank of new R-134a
refrigerant. It should be stored in the tool tray on
the top of the unit.
1. Select TANK REFIL from the main menu.
2. Connect the blue low side auto service hose to
the new refrigerant source tank and open the
tank valve. Turn the source tank upside down to
ensure all of the refrigerant is transferred to the
storage tank on the unit. Press the ENTER key.
3. Make sure you are reading pressure on the low-
side gauge.
4. Press the START key. Refrigerant will transfer to
the storage tank. The unit will shut off automati-
cally when either the supply tank is empty or the
storage tank is full.
DO NOT RECOVER CONTAMINATED REFRIGERANT WITH THIS UNIT. RECOVERING CONTAM-
INATED REFRIGERANT WILL VOID ALL WARRANTIES AND MAY CAUSE DAMAGE TO OTHER
AUTOMOBILES THAT YOU SERVICE IN THE FUTURE.
REFRIGERATION MANAGEMENT
The Refrigerant Management System built into the
3788X tracks all aspects of refrigeration usage. The
information can significantly help you manage your
automobile A/C repair business. In addition, new
federal regulations require strict records of your
refrigerant usage. The software in this system is
designed to ensure the highest possible accuracy
in managing refrigerant usage. Refrigerant meas-
urement during charging is extremely accurate. In
Charge mode, however, accuracy is plus or minus
1/2 ounce based on variations in air temperature
and pressure.
Uses of the refrigerant data include:
Improved record keeping
Accurate determination of net profits
Reduced billing errors
Minimized refrigerant loss from leaks and theft
Reduced operator errors

The unit will display "IDENTIFY REFRIGERANT ?"
To make your selection use left or right arrow keys
to toggle from YES to NO. Press the ENTER key to
make your selection and then press the START key
to start the process. If yes is selected the unit will
begin the refrigerant identification process.
If the refrigerant does not pass the identification
process (98% purity) the unit will display the error
message " CONTAMINATED" and the screen will
show the results of the identification. Press the
Reset key and follow the instructions on the screen
and the unit will clear itself automatically. Repeat
the identification process to insure the proper
identification of the refrigerant purity level.
If the unit fails the second time follow on screen
instructions and take appropriate steps to remove
the contaminated refrigerant with a separate unit
for removal of contaminated refrigerant.
