8.3.2 Checking bolt and screw medium connections

•

Check the firm seat of all screws of the medium connections (see fig. 8-4, Pos. 2 for 
example).

•

Manually verify the fastening of the actuators (seefig. 8-4, Pos. 1 for example).

8.3.3 Checking the electrical connections and earthing

•

Open the terminal or electrical control box (see Chapter 6.2).

•

Check that all electrical connections are securely seated in the terminal strips.

•

Use a suitable measuring device to check for proper earthing of the unit.

•

Close the terminal box or the electrical control box.

8.3.4 Air venting the heat exchanger

•

Air vent the heat exchanger as specified in Chapter 7.3

Fig. 8-4: 

Checking bolt and screw medium connections

Danger of electrical current!

Before completing the following work, ensure that the unit is powered down and 
secured against being energized at an appropriate point of the on-site power supply.
Before completing work on the unit, ensure that the electrical control box is properly 
closed (see Chapter 6.2)
