Advantage SENTRA SRT-1075-300 User manual

1. 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.
2. Before installing and operating the unit, be aware of and follow any local laws and codes that
apply to the installation.
3. When contacting the Service Department always have the unit Model and Serial number from
the data tag located on the side of the unit.
SERVICE DEPARTMENT: 317-887-0729
*Reference the manual for requirements for 300°F set point.
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.

This reference guide covers standard
Advantage temperature control units with the
T300 Series Control Instrument. This guide
may be used for customized units using the
T300 Series Control Instrument even when
the unit may not be physically the same as the
units depicted in the included photos. Download and read the manual before starting installation.

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. Please note: Process water piping
circuitry should be designed to 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 operations information.
1. Fill unit with water.
2. Apply power. The Standby screen will
illuminate. When Standby is displayed,
the unit is not running.
3. A System Fault may prevent startup.
Probe, cooling valve, water supply
pressure, pump overload or high
temperature limit may display once power
is applied and must be corrected prior to
operation.
4. This unit features a touch screen interface panel. Press gently on the screen to navigate. Do not
press the screen with tools or other foreign objects when navigating.
5. 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.
Typical unit with ¾ - 3 HP pump and/or 10 - 16 kW heater.

6. The unit is ready to start when no errors are shown on the
screen and pump rotation is correct.
7. 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.
8. Adjust the setpoint to the desired value by pressing the Up or
Down button until the value is displayed.
8. The unit will heat or cool to maintain the setpoint temperature.
Stop Unit Refer to the Manual for complete details on shut down information.
1. Decrease the setpoint temperature lower than 85°F and
allow the unit to cool to the temperature.
2. Press the Stop Button to disengage the pump.
3. Caution. Dissipate static pressure before disconnecting hoses.
4. A pump seal cooling feature can be selected from the Features
