Make the connection as follows:
1. Open the unit's cover.
2. Insert the cables into the unit.
3. Connect the unit with
a controller and the power
supply.
See electrical drawings.
4. Install all removed parts.
Check all plug and terminal
connections to verify
that they are tight and make
a permanent contact. Tighten
as required.

Leak testing
The leak test is carried out after
the connection has been made.
1. Flush the system twice with tap
water.
2. Clean the sieve insert on
the dirt trap.
3. Fill the system with water
again and bleed the unit
at the manual bleed valves.
4. Adjust the test pressure to at
least 200 kPa (2.0 bar).
5. Check the connections for
leaking water after a period
of at least 24 hours . If leaks are
visible, the connection has not
been properly made.
Tighten the connection
or establish a new connection.
6. After a successful leak test,
remove the excess pressure
from the medium piping
if a water-glycol mixture is used
or adjust the non-circulating
pressure to the required system
pressure.
