Prior to disconnect and remove the old MCX controller it is important to depressurize the ammonia side of the purger unit

by following these steps (see g. 1)

1. Close all supply lines from the purge points of the ammonia system (a)

2. Restart the controller to force pump-down

3. Wait for 20 minutes

4. Stop the compressor and other connected devices by switching OFF:

5. Close the SVA shut-o valve in the drain line (located under the IPS8 (b))

6. Release the remaining system pressure to ambient pressure by opening the SNV drain valve (c). This can also be done by

attaching a permanent magnet on the built-in Main Purge valve (YV1 - AKVA 10) valve, for forced opening.

1) Enter password 200 (Main screen\Start\Login\ and enter password).

2) Enter number of Purge point in question for the particular application (Main screen\Parameters\Unit cong\Valve settings\ and

enter the valve in Parameter V10, Max_PP).

3) See general IPS User Guide/Start Up instruction. The pre-programmed MCX15B2 (code number 084H5067) is plug & play ready,

and only where customer specic settings are applicable, these values must additional be entered into MCX15B2.
