Deionized Water -
The FID 1000 and FID 2500 / hydrogen must be supplied with deionized water with
a resistivity of at least 5 Meg-Ohm/cm. Parker Balston provides a point of use accessory, the Hydro-
Gen Mate (P/N 72-230 or 72-231) that provides high purity water (>5 Meg-Ohm/cm) from tap water for
manual filling or autofilling the generator. Water pressure from a deionized source or from the Hydro-
Gen Mate to the FID Gas Station should not exceed 30-60 psig.
Resin Bed -
FID gas stations are supplied with a resin bed to be installed in the water fill reservoir.
This is to ensure proper water quality is being supplied to the Hydrogen system. A message on the
front display reading "check resin bed or 75% usage" is a reminder to occasionally check resin. It
needs to be replaced only if color has changed to orange on more than 75% of the cartridge.
To install resin bed, remove water bottle cap. Remove resin cartridge from sealed bag and set resin in
bottle. Screw cap securely on water bottle (see Figures 8 and 9).
Caution: Cell contamination is a cumulative and irreversible process which will eventually
cause an over-voltage fault, automatically shutting down the generator. The deionizer resin bed
is for a final decontamination stage and should not be used to purify low grade water.

Compressed air -
The Parker Balston FID 1000 and FID 2500 Zero Air Generators require a source
of clean compressed air for optimal operation. The compressed air should be as close to instrument
quality as possible, and supplied at a pressure and flow rate above that required at the point of use.
The temperature and/or dewpoint of the supply air should be at room temperature (or lower), and
it should be relatively free from compressor oil, hydrocarbons, and particulate matter. Contamina-
tion of the catalyst bed may occur if it is exposed to certain compounds (see warning below). If the
compressed air supply has excess water, oil, or particulate contamination, install extra prefiltration
upstream from the unit (see Recommended Accessories, page 20).
Chlorinated hydrocarbon compounds and chlorofluorocarbons (or freons) will permanently
contaminate the hydrocarbon catalyst module in the FID ZAG generator. Extreme care should
be taken when specifying an air supply for the generator to ensure that these compounds are
not present in the air supply nor likely to get into the compressor providing air to the generator.
The hydrocarbon catalyst module can also be contaminated by high concentrations of lead,
sulfur, or phosphorous compounds, heavy metals, and long chain polymers. Care should be
taken to avoid introducing these compounds into the Parker Balston FID Gas Station. None of
these compounds are to be stored near the inlet to the compressor supplying the system with
compressed air. The intake for the compressor should be vented to the outdoors.
Connect the compressed air supply to the 1/4" NPT (female) inlet port in the top center of the genera-
tor, back of instrument (see Figure 10).
Piping Components, FID 1000 and FID 2500 / ZAG -
The inlet port for the Parker Balston FID 1000
and FID 2500 Zero Air Generator is a 1/4" NPT (female) and is located at the top center of the rear
panel (see Figure 10). Inlet tubing and fittings should be clean and rated for 125 psig (8.5 Barg),
minimally. The tubing and fittings used downstream from the FID 1000 and FID 2500 should be clean
stainless steel or pre-cleaned refrigeration-grade copper (1/8" od x .030" wall) and rated for 125 psig
(8.5 Barg).
