10.5 Manual test

10.5.1 Introduction

At manual test some heat pump controller functions are inactivated. Therefore, don´t set the heat pump into

operating conditions that can damage the installation.

The installation may only be commissioned if the heating system, water heater and brine system have been

filled and bled. Otherwise the circulation pumps will be damaged.

Any alarms that may occur in connection with the installation must be fault-traced.

For heat pumps DHP-H Opti Pro SP and DHP-L Opti Pro SP (1-phase) it is imperative that the hot water tem-

perature changes from default setting 95 °C to 85 °C.

When bleeding the circulation pumps, water can come into contact with electrical components. Therefore,

protect the electric panel against water.
