Water circuit pipework connection
Shut-off valves must be inserted in the refrigerated water pipes in order to disconnect the
system from the machine.
After connection to the system, a water tightness check must be carried out on both the
connections and the machine in order to avoid any damage for the area below the machine.
Condensate drain
There are three condensate drains: one for the the dehumidifying section, otehr two drains are
for condensation from the recuperator, summer and winter. These two drains must have drain
traps to prevent the suction of air which will avoid proper drainage of the condensate. The drain
traps must be independent, with a minimum height difference of 40mm and must be installed
nearby the machine.
Do not connect the condensate drains directly into the sewer system because in periods when
the machine is not used there could be spread of unpleasant odours.
