The pressure switch is mounted on the back of the vertical
panel that separates the electrical components from the
pump/heater section of the unit. The pressure switch can be
adjusted by using the screws located on top of the pressure
switch. When looking at the front of the pressure switch, the left-
hand screw adjusts the differential and the 
right-hand screw adjusts the set point. The differential is factory
set for 10 PSI (.7 Bar) and should not need to be changed. The
set point can be adjusted by turning the right-hand screw until
the set point indicator points to the desired pressure. 

Pressure Relief Valve 

The pressure relief valve is a safety device designed to vent the
system if the operating pressure exceeds 150 PSI (10.5 Bar).
The pressure relief valve is located on one of the heater tubes.
The pressure in the process loop is the sum of the cooling water
supply pressure and the pressure added by the temperature
controller pump. It is possible that a high pressure cooling water
source and/or a low flow application will cause periodic 
pressure relief valve venting during normal operation. If you are
experiencing this, please contact our Tech Service Department
for assistance and have the serial number and model number of
the unit as shown on the nameplate located on the back 
of the unit.

Standard Options

The following options are the most common standard options
that we offer. In addition to the options shown we specialize in
offering unique options for our customers as are needed for
their particular application. If you are unable to find information
on an option of your unit please refer to the drawings that where
shipped with the unit or contact our Tech Service Department for
further information.

Stacking Bracket Kit (RA & RB series)

RA Series units can be stacked to minimize floor space require-
ments. A stacking bracket kit can be used to allow one unit to
be placed on top of another.

Mold Water Purge

The mold water purge option allows the mold circuit to be
purged of water by an external compressed air source. For ship-
ping purposes, the kit is shipped separately and will require field
installation. To perform a mold purge, follow the steps below in
sequence. 

1. Press the Stop button. This leaves the unit on but puts the

microprocessor in an inactive mode. The Power button light
should still be illuminated.

2. Close the valve on the Cooling Water In line to shut off the

supply of water. 

3. Connect the compressed air supply to the ¼" ball valve on

the back of the unit.

4. Open the ¼" ball valve to let the compressed air into the

mold circuit.

5. Press the Purge button on the control panel and hold it

down for 30 to 60 seconds or until the connecting water
lines stop shaking. When the water lines stop shaking you
can assume that the water has been purged.

6. Close the ¼" ball valve and disconnect the compressed air

line.

7. Close the valves on the Cooling Water Out, From Process

and To Process lines.

8. Open the pressure bleed line to pressurize the mold circuit.

After the pressure is relieved, disconnect the hoses from the
mold. The purge cycle is now complete. 

Crash Cool 

This option provides an additional solenoid valve piped in 
parallel to the vent/cooling solenoid valve. When activated, more
cooling water is allowed into the system providing quicker
process cooling. Enabling the Crash Cool switch located on the
left side of the control panel activates this function. The Crash
Cool solenoid valve will remain open as long as the Crash Cool
switch is enabled. 

Heat Exchanger (RA & RAD series)

The heat exchanger option uses a 4.0 ft² copper tube heat
exchanger to isolate the cooling water source from the process
water after the process is initially filled with water. The heat
exchanger is designed to fit within a heater tube. Due to space
restrictions in the cabinet, this option is only available on units
with 0 KW through 12 KW heating capacities. The process 
circuit is filled separately by bypassing cooling water into the
process circuit. The cooling supply line will be used for 
expansion during operation. This option also includes a 
separate vent solenoid valve. 

PREVENTIVE MAINTENANCE

Once the unit has been placed into service, the following 
maintenance procedures should be adhered to as closely as
possible. The importance of a properly established preventive
maintenance program cannot be overemphasized. Taking the
time to follow these simple procedures will result in substantially
reduced downtime, reduced repair costs, and an extended 
useful lifetime for the unit.
