Union screwed connection
Water pipe insulation
For connecting the unit to the external system remove the protective caps
from the fl anges of the water pipes.
Caution:
Water remaining from the test run may escape when the pro-
tective 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.
Note:
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 limit the
introduction of hot ambient air.
Screw the water pipes of the cooling 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 using the fi lling
connections and the Schrader valves for bleeding (see refrigerant diagram).
