Instructions
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 fig. 1)
- Close all supply lines from the purge points of the ammonia system (a)
- Restart the controller to force pump-down
- Wait for 20 minutes
- Stop the compressor by turning the compressor switch QM1 to the off position
- Close the SVA shut-off valve in the drain line (located under the IPS8 (b))
- 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 AKVA 10 valve for forced opening
- Switch QM2 to the on position
- Configure the number of purge points (see IPS 8 user guide): Activate multipurger (label y02) Enter the number of purge points
- Configure any other customer specific setting:
The pre-programmed MCX15B (code 084H5052) is plug & play ready, and only where customer specific settings are applicable, these values must be entered.
