Advantage Sentra SR Series User manual

This reference guide covers standard Advantage temperature
control units with the G Instrument. This guide may be used for
customized units using the G Instrument even when the unit may
not be physically the same as the units depicted in the included
photos.
1. A manual is available at www.advantageengineering.com/Sentra-SRG or by scanning the QR
code on the back of this document. Download and read the manual before starting installation.
2. This unit is designed to be used with water as the circulating fluid. The quality of fluid used in
your temperature control unit will greatly effect its short and long-term operation. Lack of as
well as improper water treatment can damage the temperature control unit by causing scale
build-up, excessive corrosion and/or bacterial contamination. It is the equipment owner’s
responsibility to prevent damage caused by poor water quality. The services of a water
treatment professional is recommended.
3. Before installing and operating the unit, be aware of and follow any local laws and codes that
apply to the installation.
4. When contacting the Service Department always have the unit Model and Serial number from
the data tag located on the side of the unit.

Maximum Setpoint : 250°F*
Installation
Before Installing or Operating
Refer to the Manual for complete details on Installation.
1. Electrical: Be certain all electrical connections are tight in the unit. Install unit power cord
(when supplied) to power disconnect switch. Applied power must be equal to the unit voltage
and amps listed on the unit data tag. Follow all applicable local and national electrical codes.
2. Plumbing: Care should be taken to use materials (hose, rigid piping, valves or filters) rated
for the temperature and pressure duty of your unit. Most units have a maximum operating
temperature of 300°F or less and a maximum pressure of 150 PSI. The unit is most efficient
when full size plumbing is run from the unit connections to and from the process. If necessary,
reduce the plumbing size at your process, not at the unit.

3. Connect the unit’s To Process port to the Water In port on
the process manifold.
4. Connect the unit’s From Process port to the Water Out port
on the process manifold.
5. Note: Circuitry should avoid an excessive use of elbows
and/or lengths of pipe or hose. If hose is the material of
choice, avoid tight twists or curls and excessive lengths.
6. Valves and lters may be installed in the process water
piping circuitry to facilitate service and maintenance,
provided that such devices maintain the full inside diameter
of the process connection. If installed, all such devices must
be open and clean during unit operation.

7. Connect Unit drain to plant’s open drain, tower water system return or chilled water system
return. The factory recommends a minimum of 20 psi pressure differential between the water
supply and drain line. A larger differential may be required for larger cooling needs.
8. Connect Unit water supply to plant’s city water or well water source or tower water supply or
chilled water supply. Water supply pressure requirements vary with operating temperatures as
shown in the chart below.
Start Unit Refer to the Manual for complete details on start up and operation information.
1. Fill unit with water. Apply power. When Standby screen is
displayed, the unit is not running.
• Status : Ready. Indicates the unit is ready to start.
• Status : Not Ready. Indicates the presence of a
sensor probe, pressure switch or motor overload fault.
See the troubleshooting and maintenance portions
of the manual for Information. The fault must be
corrected in order to continue operation of the unit.
2. This unit features an LCD screen. Use the five soft touch
buttons to navigate the available screens and select
parameters.
3. Determine that the pump is rotating in a clockwise direction
when viewed from the rear of the motor. Follow the
instructions in Section 3.2 of the factory operations manual.
WARNING: proper care should be employed when checking pump
rotation as power is applied to the unit at this point.
4. The unit is ready to start when Status
Ready is shown on the screen and
pump rotation is correct. Press the green
start button. The unit will auto vent if the
fluid temperature is below 100°F or as
programmed in the features menu.
