Open both the Fill and Service valves on the top of the module by pushing in and turning
the valves counter-clockwise to the Open position.
Press and hold the trigger lever on the canister to begin filling the reservoir.
Continue to pressurize the canister, pumping slowly.
Be watchful for process fluid flowing into the overflow tank (~ 500ml after the LL1 LED
goes out @ 20
º
C). Continue to fill until the fluid in the overflow tank is about 1 inch from
its bottom. When no more air bubbles come out, release the trigger and stop pumping.
The reservoir is full.
Close both the Fill and Service valves by turning them clockwise to the Closed
position. The module is now ready for system startup.
3.2.
System Startup
The system startup procedure requires that all connections between the module and its PSC are
connected and powered on, and all fluid connections are secured. Due to the small size of the
unit’s tank, an additional fill procedure is needed to purge the entire process loop of air.
Check that the EMO button (located on the right side of the controller front panel) is
protruding. If pressed in, twist clockwise to reset. (The EMO Disable key is used during
servicing only.)
Turn on the PSC and verify that the PSC is displaying the temperature of fluid in the
module.
Press the START/STOP button to start the system, noting that the green LED (System On)
on top of the unit should turn on. Depending on the amount of external plumbing, the
red LED (LL1) will turn on to indicate a low tank volume. The pump continues to run if
only LL1 is active.
If the green system LED turns off, the fluid level is at LL2 and will shut down the system
(unless in CHX mode)
Open the Fill valve, and, using the fill canister, add process fluid. The red LED goes out
when the reservoir is half filled. Continue to fill until the fluid flows into the overflow
tank. Continue filling until the fluid level in the overflow tank is 2 inches from the bottom.
Close the fill valve and disconnect the fill canister. Empty the excess process fluid into an
authorized storage container. The system is now ready for temperature control
operation.
