Operation
Take measures to prevent people from coming into direct contact with
product outlets. Failure to do so may result in burns or other injury from
the discharge of fluids.
CAUTION
(1) When condensate flows from the condensate inlet pipe through the inlet check valve
into the body of the unit, the air in the body escapes through the exhaust valve (which
equalizes the internal pump pressure to the pressure of the condensate source) and
the float rises as shown in (A) below.
(2) When the float rises to its high level, the push rod on the snap-action unit rises
quickly, simultaneously closing the exhaust valve and opening the intake (motive
medium) valve. The pressure supplied by the motive medium causes the internal
pressure in the unit to become greater than the back pressure. The inlet check valve
closes and the outlet check valve is pushed open, thus discharging the condensate in
the unit through the outlet pipe, as shown in (B) below.
(3) As a result of the condensate in the unit being discharged, the water level in the unit
drops and the float descends. When the float reaches its low level, the push rod on
the snap-action unit moves down quickly, simultaneously opening the exhaust valve
and closing the intake (motive medium) valve and the status reverts to that shown in
(A) below.
