7COMMISSIONING

7.1 General

To ensure proper commissioning it should be carried out by an after-sales service authorized by the manufacturer. Only then can an extended warranty period of 3 years in total be granted (cf. Warranty service).

7.2 Preparatory Steps

Prior to commissioning, the following items need to be checked:

-All connections of the heat pump must have been made as described in Chapter 6.

-In the heating circuit all valves that could impair the proper heating water flow must be open.

-The air intake/discharge path must be unobstructed.

-The sense of rotation of the fan must correspond to the direction of the arrow.

-An operating mode must have been set on the remote control.

-Proper condensate drainage must be ensured.

7.3 Procedure

The start-up of the heat pump is effected via the remote control.

Where an overflow valve is fitted to assure the minimum heating water flow rate, the valve must be set in accordance with the specific requirements of the heating installation. An incorrect setting may result in various error symptoms and an increased electric power consumption. To correctly set the overflow valve, the following procedure is recommended for the "heating mode":

Close all of the heating circuits that may also be closed during operation (depending on the type of heat pump usage) so that the least favourable operating state - with respect to the water flow rate - is achieved. Typically these are the heating circuits of the rooms on the building's south and west sides. At least one heating circuit must remain open (e.g. bathroom).

The overflow valve is to be opened to such an extent that based on the current heat source temperature the maximum temperature spread between heating supply and return flow temperature is obtained, as indicated in the table that follows. The temperature spread should be measured as closely to the heat pump as possible. In mono-energetic systems, the electric heating element is to be deactivated.

The following procedure must be observed so that the commissioning activities can be carried out without any problems:

a)Close all heating circuits.

b)Open the overflow valve all the way.

c)Wait until the buffer tank has reached a temperature of approx. 25 °C.

d)Subsequently, slowly reopen the valves of the heating circuits, one after the other, in such a way that the heating water flow rate is continually increased by slightly opening the related heating circuit. When so doing, the heating water temperature in the buffer tank must not fall below 20 °C so that the heat pump can be defrosted at any time.

e)Once all heating circuit are fully open and a heating water temperature of approx. 20 °C is maintained in the buffer tank, the minimum flow rate must be set on the overflow valve and the heating circulating pump.
