er model, open any manual water inlet valves wide
open. Start the unit by pushing either the “CONSTANT
RUN” button or one of the “AUTO” buttons. Since the
unit is equipped with a minimum (65 psig, 4.5 Bars)
pressure discharge valve, no special procedure to
maintain unit reservoir pressure is required.
Unit Hot – No warm–up period is required. If the unit
is a water–cooled heat exchanger model, open any
manual water inlet valves wide open. Start the unit by
pushing either the “CONSTANT RUN” button or one of
the “AUTO” buttons.
DAILY CHECK – Refer to Section 8, “Maintenance
Schedule,” page 48.
STOPPING THE UNIT – Press “STOP–RESET” but-
ton. The oil reservoir will automatically blow down as
the motor stops. If the unit is a water–cooled heat ex-
changer type, close any manual water inlet valves.
