Select hydraulic pipes with diameter suitable to their equivalent length (considering pressure losses
by curves, unions, etc.), to the water flow, to the circulation pump head. The following minimum
diameters are suggested:

Recommendation for GS and GES Condenser Water Systems
On new or renovated condenser water systems, ensure that the external pipework is thoroughly flushed, to remove
construction debris and other particulate matter, before connecting to the new Stulz cooling units. A strainer should
be fitted at the unit inlet, to protect the heat exchangers from fouling and possible blockage.
The strainer should have a mesh size of 0.5 mm. Be aware that any fouling or blockage of the heat exchanger result
in a reduced water flow, loss of efficiency, possible damage to the heat exchanger and subsequent unit failure.
Connection with external
thread
For connecting the unit to the external system remove the protective caps or sealing
disks of the screwed connections.
Water remaining from the test run may escape when the protective
caps are removed.
The water connections end with an external thread. Screw the lines of the external
system to the lines of the unit respecting the designation at the unit.
Insulate the water pipes with the diffusion tight insulating material, to prevent the
introduction of ambient air heat and the formation of condensate at the pipes.
Fill and bleed air from the cooling water circuit by means of the filling connections
and the schrader valves for bleeding (see refrigerant diagram).
