WARNING: Improper water treatment will void unit warranty.
1.4 WATER TREATMENT
A. The 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.
B. The use of untreated or improperly treated water in a temperature control unit may result
in scaling, erosion, corrosion, algae, bacteria or slime. The manufacturer recommends
ltering the process water to prevent solids from plugging critical parts.
C. It is recommended that the services of a qualied water treatment specialist be engaged
to determine what water treatment is required.
D. Advantage assumes no responsibility for equipment failures which result from untreated
or improperly treated water.
E. Do not use deionized water in this unit. Some customized units may be compatible with
deionized water. Consult the factory before using deionized water.

2.1 GENERAL
A. 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.
B. Be certain all process piping materials have the equivalent or larger diameter of the
particular process connection.
2.2 TO AND FROM PROCESS CONNECTIONS
A. Connect the unit’s To Process port to the Water In port on the process manifold.
B. Connect the unit’s From Process port to the Water Out port on the process manifold.
C. 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.
D. 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.
*Connect Unit water supply to
plant’s city water or well water
source or tower water supply or
chilled water supply.
**Connect Unit drain to plant’s
open drain or tower water
system return or chilled water
system return.

2.3 WATER SUPPLY CONNECTION
A. Connect the unit’s Water Supply port to the plant’s city water, well water, tower water or
chilled water supply.
B. The factory recommended minimum operating water supply pressure requirement is
60 PSI. The required water supply pressure retains process water in a liquid state at
temperatures over 180°F. Failure to maintain the required water supply pressure will
cause premature failure of and increase maintenance in susceptible areas such as the
shaft seal and heater.
C. Static water supply pressure can be determined at the unit’s
location by reading the unit’s 0-160 PSI pressure gauges
when the unit’s pump motor is OFF.
D. If water supply pressure as read on the unit’s pressure
gauges exceeds 75 PSI, a pressure reducing valve
must be installed in the water supply line (refer to section
7.3 of this manual for installation information). The factory
recommended ‘regulated pressure out’ is 60 PSI.
2.4 DRAIN CONNECTION:
A. Connect the unit’s DRAIN port to one of the following, determined by the water supply
source:
1. Open drain for well or city water supply.
2. Tower water system return for tower system water supply.
3. Chilled water system return for chilled water system supply.
B. The factory recommends a minimum of 10 psi pressure differential between the water
supply and drain line for proper cooling.
1. The amount of cooling provided by the unit depends on:
a. The cooling valve size
b. The pressure differential across the valve
c. The temperature difference between the unit set point and the cooling
water temperature
d. The cooling valve position
2. Consult factory when selecting the correct cooling valve for your application.
Typical pressure reducing valve
installation (shown on S-925 model).
WARNING: Check local codes to determine proper use of back flow prevention device in
water supply line.

3. In general the standard ½” cooling valve will provide approximately 24,0000
Btu/hr (7 kW) of cooling per every 10°F difference between the cooling water
temperature and the process set point based on 25 psi delta p across the cooling
valve with ½” supply & return connections. Connecting the unit with ¾” or 1”
cooling water supply and return connections will increase the cooling capacity of
the unit.
C. For most applications, the drain line should not be valved. However, for installations
with a pressurized drain system, it may be necessary to install a valve in the drain line.
In such cases, the installed valve must be fully opened after installation and the valve
handle removed to prevent operating the unit with a closed drain valve. The valve handle
can be reattached to the valve body when it is necessary to close the valve.
D. CAUTION: The unit must never be operated with a closed drain line valve. A closed
drain line valve prevents adequate system cooling and will lead to unit overheating.
Overheating of the unit may lead to unit damage and/or serious personal injury.
2.5 ELECTRICAL CONNECTION
A. Standard Models
1. Electrical power supply requirements for standard units are identied on the
equipment data tag. Verify that available voltage supply is the same as the unit’s
voltage requirements.
WARNING: DO NOT CONNECT THE UNIT TO A VOLTAGE SUPPLY SOURCE
NOT EQUAL TO THE UNIT’S VOLTAGE REQUIREMENTS AS SPECIFIED ON
THE UNIT’S DATA PLATE.
Use of incorrect voltage will void the unit’s warranty and cause a signicant
hazard that may result in serious personal injury and/or unit damage.
2. For standard units with 10 and 16 KW heaters and up to 3 horsepower pumps, a
four conductor cable, 10 foot in length, is provided for connection to an operator
supplied fused disconnect.
3. For units with 24 and 34 KW heaters, the operator must provide a four conductor
power cable and the fused disconnect.
4. The owner supplied fused disconnect must be sized and installed according to
the unit’s power supply requirements and local electrical codes.
B. Models With Factory Included Disconnect Switch and Other Custom Features
1. Some units may be customized and include a factory supplied power disconnect
switch and/or higher specication electrical enclosure. Electrical power supply
requirements are identied on the equipment data tag. Verify that available
WARNING: Never operation the Temperature Control Unit with a closed drain.

voltage supply is the same as the unit’s voltage requirements.
WARNING: DO NOT connect the unit to a voltage supply source not equal
to the unit’s voltage requirements as specied on the unit’s data plate. Use
of incorrect voltage will void the unit’s warranty and cause a signicant
hazard that may result in damage to the unit or serious personal injury.
2. Appropriate conduit and ttings should be selected which will maintain the
integrity of the cabinet.
3. Supply a power conductor sized according to the unit’s power supply
requirements. Connect the power conductor to the unit’s power supply entry
terminal block.
C. Control Circuit Wiring
1. The unit’s supplied control circuit is 110 volt, 1 phase, 60 cycle. The control circuit
is supplied by the factory installed transformer. A control circuit fuse is provided.
D. General
1. Make certain all ground connections to the unit
are properly affixed. A proper connection to
earth ground is required. A conduit ground is
not a reliable conductor!
2. Make certain the power conductor,
disconnecting means, and fusing are properly
sized according to the unit’s power supply
requirements.
3. Make certain all electrical connections are
tightly affixed. Any loose wiring connections
must be tighten before engaging the power
supply.
4. Make certain no moisture or standing water is present inside the electrical
cabinet.
WARNING: Do not connect the unit to a voltage supply not equal to the unit’s voltage
requirements as specified on the unit’s data plate. Use of incorrect voltage will void the unit’s
warranty and cause a significant hazard that may result in serious personal injury and unit
damage.
WARNING: Electric Shock Hazard. High Voltage is present in the electrical cabinet.
Disconnect power before servicing. Follow all facility lock-out tag-out procedures.
