Water Connections
To insure the system can overcome a drain pressure the system should be operated so the
discharge pressure of the system is 10 psi greater than drain pressure. To achieve this the system
should be equipped with a valve in the process line to restrict flow.
Note: This system is equipped with an automatic fill feature.
Unit Operation
The temperature control unit designed to circulate water through a process and to precisely,
automatically and reliable maintain the water temperature at the selected set point temperature.
The operating range of the unit is from 70
F (21.1
C) - 180
F (82.2
C). The system is well suited
for use with city water, water from chillers, or cooling towers to provide the cooling water supply.
When the system is connected to the power source, an indicating light connected to a level probe
inside the tank will indicate whether the water has been filled to the correct level. The system will
automatically fill the tank to the correct level using the cooling water supply. When the system is
operating and there is too little water in the tank, the lamp lights, the pump stops and heating
ceases.
The microprocessor controls the temperature.
If a leak occurs in the mold or in the process, the built-in push-pull system permits stable
temperature control without interrupting production.
Through the use of the vacuum adjusting valve, the push-pull system makes it possible to supply
pressure to leak and vacuum from the leak back to the unit.
If a leak occurs, the flow through the circuit should be arranged so that the leak is at the end of
the water circuit.
Initial Starting Procedure
Turn on the water supply connected to the Mokon temperature control system. (See
Section 2.5 for water connection)
Turn on the electrical main disconnect switch. (See Section 2.4 for electrical connections)
If provided, turn on the electrical box door disconnect switch.
Check the pump rotation by turning on the system momentarily (press the “Start” button
then the “stop” button). As the impeller slows down, check the pump rotation. If the pump
is not rotating in the direction indicated on the motor (clockwise from the lead end), reverse
any two (2) power cord leads to change the direction of pump rotation. (See Section 2.4)
Restart the system and set the controller to the minimum temperature. (See Section 5 for
controller instructions)
Allow the system to run for several minutes with the controller set to the minimum
temperature to remove air from the system.
Set the controller to the desired temperature. The system will reach the set point
temperature. (See Section 5 for controller instructions)
