5 – Turn the pump switch on
the electrical control panel to
the initial operating (MANUEL)
position.
6 – Observe the operation of the pump. The
pump will start to fill the coil. Continue this
process until the first start-up valve (By-
Pass) receives water.
Note : The first start
valve is kept open to
check that the coil is
fully loaded. Do not
switch on the burner
until you see that the
water is coming out of
the start-up valve fully.
