FIRE/EXPLOSION HAZARD WARNING.
WARNING
During operation, take precautions to ensure that combustible materials are always
kept at a safe distance from the radiant energy. This heater is not intended for use in
hazardous areas where flammable vapours, gases or liquids or other combustibles are
present. Remember that objects placed under an infrared heater can take a while to reach
stabilized temperatures. If you are unsure of the suitability of THE HEATER for the intended
application, check with the factory for recommendations. Failure to comply can result in
personal injury and/or property damage.

DESCRIPTION
1.
The OKA radiant heater is suitable for process heating
in non-hazardous areas protected from rain, snow
or splashing, where heating element temperatures in
excess of 1382°F (750°C) will not present the risk of fire or
explosion. This heater is not intended for use in comfort
heating applications.
2.
The OKA heater is available with metal sheathed, quartz
lamp or quartz tube heating elements. Use heaters with
metal sheathed elements where there is heavy vibration or
mechanical shock. Quartz tube or quartz lamp elements
are very fragile and require extreme care in handling.
Heaters utilizing quartz tubes or quartz lamps are
unsuitable for applications in locations where the risk of
heavy vibration or mechanical shock exists.
B.
INSTALLATION
WARNING
WARNING. The system designer is responsible for the
safety of this equipment and adequate backup controls
and safety devices must be installed. Failure to comply
could result in personal injury and/or property damage.
CAUTION. Heaters must be installed and wired by
qualified personnel in compliance with local codes.
CAUTION
3.
A minimum of handling of the quartz sheath is
recommended since any type of contamination on the
sheath may reduce service life.
4.
On CE marked heaters which are being installed in the EU,
the installation of heater shall be in accordance with the
Low Voltage Directive 73/23/EEC, and any applicable local
jurisdictional requirements.
1.
Verify that the nameplate voltage and wattage are suitable
for use on the available electrical power supply. Do not
connect the heater to an electrical supply voltage other
than shown on the product label.
2.
For metal sheathed heaters, install proper ground fault
protection to prevent personal injury and/or property
damage.

holders as far as possible toward the centre of the
fixture and loop the element wire over the electrical
terminal leaving very little slack in the wire. Note
that the ceramic blocks are designed to slide freely
