Filling the Closed Loop System
Cl If the Closed Loop System is not filled properly the unit
will overheat, one or both lights sources will shut themselves
off randomly under heavy usage and damage to the unit will
be the result.
•
Hook a hose to the bleed valve and put the hose end into a bucket.
•
Turn the power on, and set the temperature level in the integrator program
to 55°F to open the solenoid valves.
•
Open the "outlet" valve and then the "inlet" valve of the chiller to allow
the water into the heat exchangers.
•
Slowly open the bleed valve to let the air out of the cooling system.
•
Close the bleed valve when there are no more air bubbles in the system.
•
Set the temperature in the program to appropriate level depending on
application (approx. 70°F).
Note: This setting can be changed in the future for different applications.
•
Once the system has been bled make sure the bleed valve is closed and
remove the bleed valve handle.
Checking the chiller if the Closed Loop System is getting to hot or shut-
ting itself down
•
Make sure temperature and pressure in the system meets those in section
Cooling Requirements.
•
Make sure the air in the system is properly bled as described in Filling
the Closed Loop System.
•
Make sure the four blowers in the back of the unit are all spinning.
Turn the unit off and wait for the cool down cycle to finish.
Remove the upper and lower rear panels see DETAILS A and K in section
Electrical Connections.
Remove the rear plate item 4 in section Closed Loop Cooling Assembly
drawing and turn the unit on to inspect the blowers.
•
Check the 3 flow solenoids feeding the heat exchangers to make sure
they are operating.
Turn the unit off and wait for the cool down cycle to finish.
Open each side door and unplug the 5 pin din socket in the front of each
light source power supply then close both doors.
Remove the bottom rear panel in the back of the unit.
When looking at the back of the unit locate the 3 flow solenoids on the
left side just at the bottom of the top rear panel (see Closed Loop Cooling
Assembly Item 5).
