2.6 Locating the Equipment

This equipment is not suitable for use in any Hazardous, Flammable, or Explosive environments. Keep the generator away from excessive
heat and naked flames.

2.6.1 Environment

The equipment should be located indoors in an environment that protects it from direct sunlight, moisture, and dust. Changes in temperature,
humidity, and airborne pollution will affect the environment in which the equipment is operating and consequently may impair the safety and
operation.
It is the customers' responsibility to ensure that the environmental conditions specified in table 2.1 are maintained.

2.6.2 Space Requirements

The equipment should be mounted on a flat surface, capable of withstanding the weight of the equipment and all ancillary parts. A minimum
clearance of 150mm (5.9in) should be provided on all sides of the generator for air flow. Additional space should be provided so that the
generator can be moved to allow unrestricted access to the generator during servicing and maintenance.
Do Not block the side vents or the fans located on the rear panel of the generator.
When considering the vertical clearance you must take into account the height required when the front upper access panel is in the open
position. Refer to table 2.2 for overall dimensions of the equipment.
Do Not position the equipment so that it is difficult to operate or disconnect from the electrical supply.

2.6.3 Ventilation Requirements

The accumulation of hydrogen can displace oxygen thereby creating and asphyxiation hazard. Always ensure that the equipment is operated
in a well ventilated area.

2.6.4 Water Supply Requirements

Generators fitted with automatic water fill system maintain the water level from a gravity fed fresh deionised water supply. Refer to "Technical
Specification" on page 3 for the supply requirements.
The use of any water, other than deionised water (Deionised, ASTM II, >1 M , <1 S, filtered to <100 m), within this generator will damage and
reduce the life time of the hydrogen cell.
The generator should be connected to the supply using 1/4" Tygon or PTFE tubing (not supplied).
Note. The automatic water fill system is available as a factory or field fit optional extra. Contact Parker Hannifin for further details.

2.6.5 Electrical Supply Requirements

The equipment should be connected directly from the fused IEC 320 inlet socket to the electrical supply using the power cord supplied. The
equipment should be positioned so that it can be connected to the electrical supply without the use of an extension cord.
It is the customers responsibility to provide a fused electrical supply to the equipment (Refer to table 2.1 for the electrical specification). It is
recommended that this supply have surge protection.
The equipment is connected to protective earth (ground) through the power cord. It is essential that electrical supply is equipped with a
protective earth (ground) terminal. If an alternative power cord is used to connect the equipment to the electrical supply, ensure that it is
suitably rated for the application and contains a protective earth (Ground) conductor.
