To re-start the Parker Balston Hydrogen Generator after a temporary shutdown, switch the hydro-
gen outlet valve to “Auto”, set the hydrogen output pressure to the desired reading, and adjust the
flow using the (customer-provided) flow control device. If the cell has cooled during the shutdown
period, the hydrogen generator will require 2 to 4 hours to achieve its specified hydrogen flow rate.
If the Parker Balston Hydrogen Generator is being shut down for shipment or for storage for an ex
-
tended period, then the system must be drained and plugged. Instructions for long term shutdown
and plugs may be requested from Parker Hannifin Corporation.
Failure to drain the generator
prior to long term shut down will damage the electrolytic cell and void the warranty.

All maintenance activities should be performed by suitable personnel using reasonable care.
To avoid electrical shock, disconnect power before servicing the generator.
The primary maintenance activities required by the Parker Balston Hydrogen Generator are filling
the feed water bottle and changing the electrolyte solution. If necessary, the Parker Balston Hydro
-
gen Generator may be wiped clean with a dry cloth on an as needed basis. Do not use water, aero-
sols, or other cleaning agents to clean the unit. Use of any liquid detergent to clean the generator
could present an electrical hazard.
If the Parker Balston Hydrogen Generator is operated 24 hours per day at its rated maximum flow
rate, the water in the feed water bottle should last for 8 to 10 days. Parker Hannifin recommends
checking the water consumption rate on a routine basis until a filling schedule can be established.
(Note: If auto water fill is used this is not necessary.) Ambient temperatures will affect water con
-
sumption, and these conditions should be taken into consideration when planning a refill schedule
for the hydrogen generator.
As needed, slowly refill the water reservoir with deionized water, using a funnel, to the “WATER
FULL” mark. Do not overfill. Use deionized water with a rating of
5 Megohm-cm
or better. Fail
-
ure to use a funnel may result in spills and subsequent damage to the generator (see warning on
page 7). If the water supply is depleted beyond the refill level, the “Add Water” message will be
displayed and the hydrogen generator will generate an audible signal.
If the water is not refilled before it drops to the minimum level, the “LOW WATER” message will be
displayed and the system will safely shut down and a more rapid audible signal will sound.
The electrolyte solution may need to be changed so that the generator can be moved to another
location OR at the direction of Tech Support due to generator performance issues. Please follow
the procedure detailed below, exactly, to ensure normal operation of the generator.
Caution:
The electrolyte is a specially prepared solution of sodium hydroxide and may be danger-
ous if handled improperly.
Read the MSDS accompanying the electrolyte solution for proper
handling and disposal procedures. Always use eye protection and neoprene or butyl gloves
when handling the electrolyte solution. In the event of a spill or splash, refer to the MSDS
accompanying the electrolyte solution for remedial actions.
Electrolyte solution drained from the generator must be disposed of according to the stan-
dards defined in the MSDS.
Note: Before changing the electrolyte, turn the Parker Balston Hydrogen Generator off and
