disconnect it from its power source and all downstream equipment. Allow the unit to cool at
least 4 hours, preferably overnight.
If the cell is drained too soon after shutdown, the hydrogen
which saturates the palladium membrane will be released too quickly and will react with the oxygen
in the air. This is a vigorous reaction which will heat the palladium and permanently damage the cell.
Protection -
Eye protection and neoprene or butyl gloves (see warning notice above.)
Electrolyte -
One bottle of Parker Balston Electrolyte Solution (P/N 920071).
Note: Use only Electrolyte Solution from Parker Balston to replace electrolyte. Use of any
substitute will damage the unit and void the Parker Balston warranty.
Miscellaneous -
Phillips head screwdriver, polyethylene catch basin (3-5 liter capacity), and funnel.
NOTE: TO MINIMIZE EXPOSURE OF THE PALLADIUM MEMBRANE TO AIR, STEPS 2
THROUGH 5 (BELOW) MUST BE PERFORMED WITHOUT INTERRUPTION. ALLOW ENOUGH
TIME (10 MINUTES) TO FINISH THIS PROCEDURE WITHOUT A BREAK.
PLEASE REVIEW THE FOLLOWING PROCEDURE AND HAVE ALL SUPPLIES READILY AVAIL-
ABLE PRIOR TO CHANGING ELECTROLYTE. FAILURE TO FOLLOW THE ELECTROLYTE
CHANGE PROCEDURE AS DOCUMENTED WILL DAMAGE THE HYDROGEN CELL AND VOID
THE WARRANTY.
The procedure for changing the electrolyte is as follows:
1 Turn off the Parker Balston Hydrogen Generator, disconnect it from the power supply, and allow
it to cool for four hours, preferably overnight. Remove the back panel from the unit by removing
the four panel screws.
2 Open electrolyte solution. Remove water fill cap from generator and insert funnel.
3 Remove the drain valve assembly from its holder and open the drain valve to empty contents
to the catch basin. Close the drain valve when draining is complete. Quickly replace the drain
assembly into its holder.
It is against federal regulations to dispose of the sodium hydroxide waste by dilution. Con-
sult federal, state, and /or local guidelines for acceptable disposal methods.

Immediately
, pour one bottle of Electrolyte Solution (P/N 920071) into the generator through
the funnel.
5 Fill the generator with deionized water, until the level indicator on the front panel is 1" below the
“WATER FULL” level (approximately 3 liters), as detailed in Preparation section (page 7) of this
manual. Do not overfill.
6 Restart the generator following the instructions detailed in the Start-up section of this bulletin
(page 6). Allow 2 to 4 hours for generator to reach flow and pressure specifications. During the
first 48 hours of operation, add deionized water, if needed, filling only until the level indicator is
1" below the “WATER FULL” level.
This equipment has fuses in both neutral and phase lines. Use care when servicing.
Occasionally, one or both of the fuses in the generator may burn out. The fuses are located in the
power receptacle on the left hand side of the generator.
Before servicing the fuses, turn the
generator off and disconnect the power cord from the power supply and the generator power
receptacle.
Both fuses should be checked each time fuse replacement is warranted. To access the
fuses, use a small screwdriver to remove the holder located in the power receptacle of the genera-
tor. Replace either one or both fuses as necessary and re-assemble.
For continued protection against risk of fire, replace only with fuse of specified rating.
