3.1 GENERAL
A. Failure to follow the factory required operation procedures may adversely affect the unit’s
ability to adequately control process temperature and may create a hazardous operating
condition which may result in unit damage or serious operator injury.
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 restart the unit after reinstallation to the same or
different process. This section includes information on system fill, electric motor
phasing (pump rotation) and process flow adjustments.
3.3 Instrument Operation - follow this segment to start up and operate the
instrument. This section includes information on automatic and manual venting,
setpoint selection and adjustment, and feature explanations.
3.4 Shut down procedure - follow this segment to shut down the unit. This segment
includes information on system cool down, shut down, electrical power supply
precautions, and disconnection from the system.
3.2 MACHINE START UP AND OPERATION
A. System Fill
1. Engage the water supply source by opening the water supply valve (customer
installed) at the unit’s location. If a valve is not installed, engage the water supply
source at the plant’s water supply central control point.
2. Once the water supply source is open, the unit will fill automatically. Allow a
few moments for the unit to completely fill. The operator can determine the unit
is properly filled when the To Process pressure gauge and the From Process
pressure gauge stabilize at equal or closely similar pressure.
3. The operator must check for any water leakage in the unit’s mechanical system,
the process, and throughout the plant’s water supply system. If a water leak
is observed, the operator must disengage the water supply system, relieve all
pressure, and repair the leak. The operator must verify the leak is repaired by
refilling the system as outlined in this procedure.
4. During system fill, air is often trapped in the water system. Air is purged
automatically via the AVT
TM
valve during initial pump start-up. All air must be
purged before the unit is engaged for process temperature control. The automatic
stat-up vent parameters are adjustable. See Section 3.5.F for more information.
Entrained air in the system will adversely affect the unit’s ability to control
process temperature and can cause heater failure when the heating elements
are exposed to this air.
WARNING: Follow all Factory operations procedures. Failure to do so may create a
hazardous operating condition which may result in serious operator injury and/or unit damage.
