Installation
Connections
Threaded connections
– Use a torque wrench when
connecting the pipe and observe the speci fi ed limits. Refer to
table on page 14.
Brazed connections – Clean by rubbing down and degreasing
the various surfaces. Use the correct brazing temperature and
brazing metal grade.
Welded connections – To minimize the heat impact of the
heat exchanger it is recommended to use TIG or MIG welding
methods. Preparation for welding: Grind inside and outside of
the pipe and, if bevelled, also the bevelled edge at least 25 mm
from the pipe edge and inward.
Note!
Before connecting the heat exchanger to the system
consider valve set-up and access points for example
to be prepared to perform cleaning.
Note!
Protect the heat exchanger from overheating by
wrapping a piece of wet cloth around the connection
while soldering or welding.
Installation as evaporator or condenser
In applications where a phase change of media occurs, the
heat exchanger must be installed vertically.
