4 WATER CONNECTIONS
Minimum water flow
Maximum water flow
Water flow-rate
The design water flow-rate must be:
inside the exchanger operating limits (see the TECHNICAL
INFORMATION chapter)
guaranteed also with variable system conditions (for example,
in systems where some circuits are bypassed in particular
situations)
If the system capacity is below the minimum flow, bypass the
system as indicated in the diagram.
If the system capacity exceeds the miaximum flow, bypass the
system as indicated in the diagram
Minimum system water content
For a proper functioning of the unit a minimum water content
has to the provided to the system, using the formula:
Minimum water content [l]
= 5 x kWf (air conditioning application)
= 10 x kWf (application with low outdoor temperature or low
loads required)
kWf = Nominal cooling capacity unit
Volume calculated does not consider internal heat exchanger
(evaporator) water content.
Water filter
Must be installed immediately in the water input of the unit,
in a position that is easily accessible for cleaning.
The filter never should be removed, this operation invalidates
the guaranty.
Recommended filter with N 25 mesh (French numbering) 0,87mm
size mesh
Size mesh = 0,87mm
