Water must be drained to avoid hoses freezing up during shipment.
Disconnect the water inlet and outlet pipe quick connectors.
Disconnecting the
cooling circuit
Prepare a flexible pipe (
A
) with a quick 1/4 NPT female connector
and another flexible pipe (
B
) with 1/4 NPT male connector.
Connect one end of pipe (
B
) on the pump, at location
”OUT”
and
place the other end in a vessel (total water volume will be greater
than one liter).
Connect one end of pipe (
A
) at location of
”IN”
and connect the
other end to a compressed air circuit (2 to 5 · 10
3
hPa).
Inject compressed air into the pump until the water has been
completely evacuated from the circuit.
Note:
as the water circuit is equipped with water valve normally
closed, some water stays into a part of the circuit. It’s not a problem
for shipping. Complete water draining will be done during pump
overhaul.
