5. Connect a refrigerant hose from the refrigerant cylinder to the fitting marked "In"
on the Charging Module. Connect another refrigerant hose from the fitting
marked "Out" on the charging module to the system being charged with
refrigerant.

Because refrigerants have high pressures at elevated
temperatures, use caution when connecting and disconnecting
hoses to the Charging Module. Always ensure hoses are properly
rated for the refrigerant being used.
Note: Prior to making the second hose connection, it may be necessary to purge
the hoses of air with a small amount of refrigerant. This can be done by
programming the Charging Module for a quantity of 1 oz. and initiating the
charge function (See Charging Module Operation).
6. You may wish to put a manifold gauge set between the Charging Module and
the system being charged. In this case, connect the hose from the fitting
marked "Out" on the charging module to the center port on the manifold gauge
set. Connect the manifold set to the system to be charged.
Charging Module Operation
Once the Charging Module has been set up as described above, it is ready for
operation.
1. Press and hold the Tare/Clear button for one second. This will clear the last
programmed target charge. You will hear a short beep to signal that the charge
is cleared.
2. Program the desired charge amount on the bottom line of the Charging
Module's display using the Up Arrow and Right Arrow buttons. Press the Right
Arrow button to position the flashing cursor on the digit to be changed. Press
the Up Arrow to increase the number in the position of the flashing cursor. If the
Up Arrow button is depressed and held, the number will increase rapidly until
the button is released. If the digit reaches "9", press the Up Arrow again to
return the flashing digit to zero.
The smallest charge increments available are 10 gm (when in kg units), .01 lb
(when in decimal pound units) and .25 oz (when in lbs/oz units).
3. Ensure the valve on the refrigerant cylinder is open.
