3.1 GENERAL
A. Failure to follow the factory required operation procedures may
adversely affect the unit’s ability to control process temperature and

unit damage and serious operator injury or death.
B. The Operations segment of this manual is outlined below:
3.2 Machine start-up/operations procedure - follow this
segment to start the unit after the initial installation or to

3.3 Instrument - follow this segment to start up and operate
the instrument controller. This section includes information
on automatic and manual venting, setpoint selection and

3.4 Shut down procedure - follow this segment to shut down

3.2 START UP/OPERATIONS PROCEDURE
A. SYSTEM FILL
1. The unit has an internal reservoir which must be filled and
maintained for proper operation.
2. Conair recommends the addition of 20% inhibited
propylene glycol to the process fluid. This should help
prevent the process fluid from freezing and internal
components from rusting. A biocide must be added to the
water to prevent organism growth in the chilled water
system. See water treatment section in section 8 of this
manual for more information.
3. Remove the top panel
to access the reservoir.
Add fluid directly to the
reservoir tank. Please
note, when the pump is
first started, and after
the process lines are
filled and entrained air
is purged, additional
fluid may be required to
restore the reservoir to
the correct level.
