Initial Calibration and Start-up Continued
A. The reading of 8" on the start-up vacuum gauge will go to 0 or higher, the system will continue to run while water flows to the
start-up/overflow drain.
B. The system will build pressure in the reserve tank to 575 psi then shut down.
If A occurs, continue on to step 5. If B occurs, skip step 5 and proceed to step 6.
Step 6. Adjust the high-low pressure switch (upper dial) downward until the system shuts down.
Step 7. After system shuts down, reduce the pressure switch (upper dial setting) an additional 50 psi (page 13).
Step 8. Adjust pressure switch (lower dial) to obtain a 75 psi pressure differential.
Step 9. Open 2" discharge ball valve in order to allow pressurized hot water to fill the plant piping network. The HelioJET may
cycle on and off when you do this.
Calibration is now complete and the HelioJET is ready for use. Simply begin using the spray guns or other spray devices that are
supplied by the HelioJET C-60. The HelioJET will cycle on and off automatically as it is used.
Routine Start-up and Shut Down Procedure
Steps 1-8 are for initial calibration and start-up only. Once the Handwheel and pressure switch have been adjusted, it is only
necessary to follow the routine start-up and shut down procedure described below.
During times of clean-up, the HelioJET should be left on. It will cycle on and off as pressurized hot water is used for clean-up
purposes.
If the system is to be turned off until the next clean-up period, follow these routine start-up and shut down procedures:
Routine Start-up
1. Be sure condensation has been removed from the steam supply line.
2. Turn power switch on.
Routine Shut Down
1. Turn power switch off.
Note: In the event that the air charge in the tank is lost, it will be necessary to recharge it. Before you begin it will be necessary to
purge the residual water that is in the reserve tank. For instructions on this procedure, refer to page 19 under the section entitled
"How to recharge the Reserve Tank". Then follow the "Initial Calibration and Startup Procedure" as outlined above. If for any
reason you must perform these procedures; remember that after the water is purged from the reserve tank it will be very important to
close the manually operated 2" Discharge Valve located at the rear of the reserve tank (see page 21, item 2). After the reserve tank is
charged with air. And the C-60 is fully charged with water pressure, you may then open the discharge ball valve and feed your plant
with pressurized hot water. If this procedure is performed out of order, the air charge will be lost into the discharge lines feeding the
plant.
If the HelioJET is left unused for a long period of time (perhaps two days or more), it is suggested that the power switch be turned
off and that the manual water and steam supply valves be closed as well as the discharge ball valve.
