26 Hydra user manual
Priming the base fills the base with fluid, pressurizes the system, and resets the system if an automatic
shut-down has occurred. The base must be primed when refilling or replacing both fluid tanks, when the
tanks have been removed for transport, after an out-of-fluid shutdown, and after a leak detection shutdown.
The base need not be primed if replacing an empty tank while the system is running: it will prime itself
automatically when switching tanks. However, priming will make the tank changeover faster.
Prime the base from the left display as follows:
1. To prevent heads from firing, verify that run is set to off, or, if there is DMX input, that all Hydra control
channels are set to no output.
2. Select the fresh tank from the
tnc
menu. When fitting 2 fresh tanks (of the same fluid), you can select
L-R
to prime both tanks simultaneously.
3. Under the left display, press menu as required to display
pri
.
4. Use the up or down keys to select
y
. Press enter.
5. Allow the base priming cycle to run until the pump stops.
6. Read the input pressure (
Pi
) value in the left display. If the value is less than the target pressure (36 psi
by default), repeat the base priming cycle. If more than three cycles are required with the default settings,
there may be a fault with the system. Contact Jem service.
7. Select the working tank from the
tnc
menu.
Priming the fluid line fills it with fluid and forces out air by firing two heads: those with the middle and last
address. This is required before first use or after opening the fluid line for draining or maintenance. The fluid
line does not require priming when refilling/replacing fluid tanks.
Prime the fluid line from the right display as follows:
1. Verify that the fluid line is closed.
2. Start the system and allow the heads to reach operating temperature.
3. Prime the base as described above.
4. Under the right display, press menu as required to display
pri
.
5. Use the up or down keys to select
y
. Press enter. This opens the base fluid output valves and fires two
heads for a period determined by the pump delay time setting. Large systems can take up to four minutes
to fill; you may need to repeat the cycle several times.
6. Select
n
to stop the cycle when both heads are firing.
To turn off the Hydra system, simply set the base power switch to the right (off) position.
The heads may be left on, with AC power applied, if convenient. The heat exchangers are automatically
switched off 20 minutes after the base is turned off to save power. When a head detects that the base is
switched back on, it switches on its heat exchanger and is ready to fire 10 to 15 minutes later.
A custom flight case is available for transporting the Hydra base. Contact your Jem supplier for information.
The base hose fluid caps are not leakproof. Remove the fluid tank hoses from the tanks for transportation
and seal the tanks with regular caps. Place the fluid tank hoses in a clean plastic bag to keep them clean.
Take care as well to keep the self-seal connectors clean.
When setting up in a new venue, run the base prime cycle after connecting the fluid lines.
