To detach male type terminals (pump side) it is
necessary to press the coaxial rings towards the
pump, and extract the terminals.
CAUTION
DO NOT FORCE THE TERMINAL IF THIS DOES NOT COME
LOOSE; EVENTUALLY, TRY TWISTING IT. THE TERMINAL
IS DESIGNED SO THAT AN INCREASE IN TENSION IN-
CREASES THE LOCKING FORCE.
The system pressure check must be carried out,
for practical reasons, by connecting on the pump
side.
Connect the manometer to the outlet duct (RHS)
and the extension tube to the inlet duct (LHS).
CAUTION
BEFORE REASSEMBLING CHECK THE TOOL DUCTS ARE
