Start-up
Preparing for Initial Calibration and Start-up
After the HelioJET C-30 has been installed, complete the following steps before attempting to start the system.
Precharge Reserve Tank
Close 2” discharge ball valve. This will prevent compressed air from entering the discharge piping that feeds the cleaning stations in
your plant (pg. 12, fig. 6).
Connect air hose line to the 1/4” tank air charge valve located at the rear of the reserve tank (fig. 6).
Charge the reserve tank with air pressure (60-120 psi).
Close 1/4” tank charge valve, remove air hose, and connect it to the air actuated steam valve (fig. 6). Charging the tank is a one time
procedure. It should not be necessary to repeat except during times of maintenance.
Pump Rotation
Be sure the manual steam valve is closed and the manual water supply valve is open. Turn the power switch on and off quickly. The
pump shaft should turn in the direction of the arrow located on the pump housing.
Pump Air Lock
Remove any air that may be trapped in the pump by loosening the release plug on the upper portion of the pump body housing. The
pump may be off, but the manual water supply valve feeding the system must be open.
Remove Condensate
Be sure all condensate from the steam line has been purged and that the steam trap is working properly.
Two Adjustments
There are two adjustments on your HelioJET C-30. You will make them during the initial calibration and start-up procedure in the
next section. Please refer to pages 7 and 12 to familiarize yourself with the location of the
handwheel adjustment
and the
high-low
pressure switch
. After you have located these two components, you may begin the calibration and start-up procedure. Please do not
arbitrarily make adjustments.
Follow proper procedures as covered in the initial calibration and start-up section below.
Initial Calibration and Start-up
Before attempting to start this system, be sure it has been installed in accordance with all previous instructions, and that the proper
procedures have been followed. If you have any questions, contact the HelioJET Technical Service Department at 1-800-444-3546.
Please read all
of the following steps before beginning, and be sure to follow them in proper order:
Step 1.
Be sure the handwheel adjustment is turned clockwise to fully bottomed position.
Step 2.
Adjust pressure switch (upper dial) to 350 psi. Note, if the maximum scale reading on your pressure switch is 600 psi, then
adjust the upper dial to 575 psi (see pg. 12, fig. 5).
Step 3.
Open manually operated water and steam supply valves to system (be sure all condensate has been drained from the steam
supply line).
Step 4.
Turn the HelioJET power switch on. Water will flow to drain from the start-up/overflow.
Step 5.
Observe the start-up vacuum gauge, and begin turning the handwheel counter-clockwise. At some point the gauge will
suddenly read a vacuum. Continue to turn the handwheel rapidly in the same direction until the vacuum reading is
10 inches
. The
handwheel is now calibrated, do not continue to adjust it. Observe the discharge pressure gauge. Pressure will build in the reserve
tank and the start-up/overflow will cease to discharge water to the drain until the system reaches its maximum pressure. At that time
one of the following two things will occur:
11
A. The reading of 10” on the start-up vacuum gauge
will go to 0, the system will continue to run, but water will again flow to the
