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 500°F or less and a maximum pressure of 75 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.

Fluid fill port:

Use when manually

adding fluid to the unit

From process

connection:

Connect to “fluid out” on

process manifold

Fluid fill/drain connection:

Use when adding fluid from a

pressurized source or when draining

majority of fluid volume from unit

Water drain connection:

Connect to one of the following:

• Plant’s open water drain

• Tower water system return

• Chilled water system return

2.2 TO AND FROM PROCESS CONNECTIONS

A. Connect the unit’s To Process port to the Fluid In port on the process manifold.

B. Connect the unit’s From Process port to the Fluid Out port on the process manifold.

To process connection:

Connect to “fluid in” on process manifold

Compressed air connection:

Connect to plant compressed air source
when purging fluid from mold to unit for
storage

Water supply connection:

Connect to one of the following:

• Plant’s city water source

• Well water source

• Tower water supply

• Chilled water supply

C. Please note: Process 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.

.

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. If unit is a Heating Only Unit, the water supply must be a minimum of 1/2 GPM at a

maximum temperature of 100°F for efcient component cooling. If the unit is a Heating

and Cooling Unit including a heat exchanger, the water supply must be a minimum of

3 GPM at a minimum temperature of 100°F. High water ow may be required for your

application depending on the process cooling requirement.

C. The factory recommend minimum operating water supply pressure requirement is a

minimum of 20 PSI. To protect the unit from operating without adequate supply water, a
water pressure switch is plumbed into the supply manifold. If the supply pressure is not

sufcient, the pressure switch will prevent unit operations.

D. On all units, cooling water circulates to the supply manifold, through the pump adapter

cooling jacket, and is then rejected to the drain manifold. This action maintains proper
pump seal cavity temperatures.

E. On units with the installed cooling option, a tube and shell heat exchanger for process

uid cooling is supplied and mounted to the expansion tank.

1. The purpose of the heat exchanger is to cool the process uid. Cooling water

from plant water supply circulates through the “tube” side of the heat exchanger.

The process uid circulates through the “shell” side. Cooling water ow is

controlled by the solenoid valve.

2. A 1/2” ball valve is placed in the heat exchanger water supply line after the

solenoid valve. The ball valve should be open during operations from 100°F to
200°F. During operations with temperatures over 200°F, this valve should be
closed. In such cases, the necessary cooling water is proportioned to the heat
exchanger through the small capillary line, which some water “steams off” to cool

the process uid. The steam and water mixture is then rejected to drain.

2.4 WATER DRAIN CONNECTION:

A. Connect the unit’s Water Drain port to one of the following, determined by the water

supply source:

1. Open water 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 20 psi pressure differential between the water

supply and water drain line for proper cooling.

1. For units equipped with the cooling feature, the amount of cooling provided by
the unit depends on:

a. Cooling heat exchanger size.

b. The cooling valve size

c. The pressure differential across the valve

d. The temperature difference between the unit set point and the cooling

water temperature

2. Consult factory when selecting the correct cooling valve for your application.

3. In general, the cooling capacity of the standard 3.5 sq ft heat exchanger is 6,000
Bth/hr (2 kW) for every 20°F difference between the cooling water temperature

and the uid temperature.

C. 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.

WARNING: Never operate the Temperature Control Unit with a closed water drain.

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.

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.

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 12 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 16 kW to 48 kW heaters, the owner 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
voltage supply is the same as the unit’s voltage requirements.
