6 Troubleshooting and remedy
Warning
Repairs to the refrigeration cycle may only be carried out by expe-
rienced refrigeration technicians. Improper repairs may cause sig-
nificant danger for the user, for which Winterhalter is not liable.
IMPORTANT You may only test the heat pump if the minimum tank level
(dry running protection) is adhered to and the cover is mount-
ed on the lamella heat exchanger. This is the only way to en-
sure air flow.
6.1 Water-related safety
To ensure fault-free operation, it is important that parameter P630 is set in
accordance with the installed water safety device.

Access the Service Menu and check whether the parameter is set correctly
(for details see PT Series service instructions):
‒
For machines with backflow restrictor type “air gap” (30000127): 50 °C
‒
For machines with backflow restrictor type “BPD” (30000128): 70 °C
