Union screwed connection
Water pipe insulation
For connecting the unit to the external system remove the protective caps from
the flanges of the water pipes.
Water remaining from the test run may escape when the protective
caps are removed.
The water connections are executed in the shape of a screw connection with a
soldering connection. Solder the part with the external thread of the connection
to the external pipes and screw the lines of the external system to the lines of the
unit respecting the designation at the unit.
If any seals are missing, these must only be replaced by glycol-
resistant rubber seals.
Insulate the water pipes with the insulating material supplied, to prevent the intro-
duction of ambient air heat as well as possible.
Screw the water pipes of the A/C unit together with the local water pipes of the
dry-cooler or the chiller.
Fill and bleed air from the cooling water circuit by means of the filling connections
and the schrader valves for bleeding (see refrigerant diagram).
