Piping Work
Water connections must be made in accordance with the outlook diagram delivered with the unit, respecting the water in- and
outlet. If air, moisture or dust gets in the water circuit, problems may occur. Therefore, always take into account the following
when connecting the water circuit:
Use clean pipes only.
Hold the pipe end downwards when removing burrs.
Cover the pipe end when inserting it through a wall so that no
dust and dirt enter.
Use a good thread sealant for the sealing of the connections
The sealing must be able to withstand the pressures and
temperatures of the system.
When using non-brass metallic piping, make sure to insulate
both materials from each other to prevent galvanic corrosion.
Because brass is a soft material, use appropriate tooling for
connecting the water circuit. Inappropriate tooling will cause
damage to the pipes.
• Be careful not to deform the unit piping by using excessive force when connecting the piping.
Deformation of the piping can cause the unit to malfunction.
• Always use two wrenches (spanners) for tightening or loosening the water connections,
and tighten connections with a torque wrench as specified in below table. If not, connections
and parts can be damaged and leaks.
• The unit is only to be used in a closed water system. If applications are in open water circuit,
it will generate Heat exchangers fouling, Corrosion, Leak.
