Charging Module Setup and Operation
Setting up the Charging Module
1 Place the Wey-TEK on a firm, level surface.
2 Connect the communication cable to both the Charging Module and
Wey-TEK.
3 Plug the AC/DC power adapter into its power supply and then connect it to
the Charging Module.
4 Turn on both the Wey-TEK and the Charging Module.
5 Position the refrigerant container on the scale platter.
6 Connect a refrigerant hose from the refrigerant container to the fitting
marked “IN” on the Charging Module.
WARNING
Ensure hoses are properly rated for the
refrigerants being used.
7 Connect an additional hose from the fitting marked “OUT” on the Charging
Module to the system to be charged.
8 You may elect to put a manifold gauge set between the Charging Module
and the system to be 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.
9 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 operating the charge cycle (See Charging Module
Operation).
Charging Module Operation
Once the Charging Module has been set up, it is ready for operation.
1 Press and hold the “CLEAR” key to start the program. This will clear the last
programmed target charge and set the bottom display to zero. When this
operation is complete, you will hear an audible 2 beep signal. NOTE: The
clear key will not reset the top display. The top display is reset to zero only
when the “CHARGE” key is activated.
2 Using the “UP” or “DOWN” keys, program the desired target charge weight.
Holding the key down will allow rapid up or down scrolling of the display.
