Filling the phx42 with H
2
Gases are typically stored under pressure in metal cylinders. Cylinders are designed to withstand high
pressures. Improper handling and use of compressed gases can result in devastating consequences. Be
sure to follow all safety guidelines outlined by your facility.
TECH TIP: Be sure to use only ULTRA HIGH PURE (99.999%) H
2
with a CGA-350 fitting when filling the
phx42.
Initial Setup of Newly shipped phx42
The battery and the H
2
cylinder are drained for shipping. Special charging and fill procedures are required.
Charge the battery:
1. PULL the Charging Port Cover (LDAR# 42013) to access the Charging Port.
Twisting/turning the cover to remove will damage the tether. It does “click” into the Charging
Port, so some effort will be required to remove the Charging Port Cover.
2. Align the red lines on the phx42 Charger and the Charging Port. Push gently and you will
feel a click.
3. Wait 90 mins.
4. Turn on the machine.
Filling Empty Cylinder with H
2
The motor needle valve for the H
2
cylinder will need time to adjust from an empty to a full cylinder.
Follow the standard “Filling the phx42 with H
2
” procedure, with the following exceptions:
• Fill as described in the normal fill procedure described below, but when the needle on the
gauge stops moving, wait 3 minutes with the valve open.
TECH TIP: After you have filled the unit with H
2
, it may take several attempts to ignite. This is because
the H
2
pressure must stabilize. The best approach is to wait 2 minutes between each ignition attempt. If
Ignition Failure continues after 3 tries, perform a self-check, and submit a failure with comments to the
LDARtools Support team.
