fitting piece for heat meter - see page 7 in the instructions, if
necessary).

have loosened during transport and handling (do NOT
overtighten!) - check that the air valve in top of the unit is
closed.

Establish a drain connection on the safety valves in compli-
ance with the aplicable legislation.
5.
Open the ball valves for HE supply and return and fill the
