4.0
To facilitate mounting, the heater has four ¼”-20 mounting
holes located at each top corner of the housing. Either chain
mounting (use eye bolts) or bolting to a non-combustible sliding
support (slotted holes) is adequate provided that the spacing
instructions as given in 3.0 are followed. Chain mounting is
preferred since rigidly mounted heaters are susceptible to warping.
The system designer is responsible for the safety
of this equipment and adequate back-up controls
and safety devices must be installed. Failure to
comply could result in personal injury and/or
property damage.
Heaters must be wired by qualified personnel in
compliance with local codes.
5.0
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.
Insulation contamination or moisture
accumulation can cause fault to the element
sheath generating arcing and releasing molten
metal. Install proper ground fault protection to
prevent personal injury and/or property damage.
6.0
The connection box volume is 3100 cm³ (190 in³).
7.0
Supply conductors to the heater must be suitable for 110°C
(230°F). The ground wire from the supply shall be connected to the
grounding connection located in the connection box.
8.0
The connection box has eight dual knockouts, ½” or ¾” and
two dual knockouts ¾” or 1”. The standard Type 1 enclosure is
suitable for dry, indoor locations only in non-corrosive environments.
9.0
For short circuit protection, heaters must be installed with
proper fast acting fuses or breakers as close as possible to the
ratings indicated on the nameplates, in compliance with the local
electrical codes.
10.0
To maximize heating efficiency, periodically wipe clean the
reflector with a cloth dampened with alcohol.

HIGH TEMPERATURE, RISK OF FIRE, FIRE/EXPLOSION HAZARD WARNING - During operation, take precautions
to ensure that combustible materials are always kept at a safe distance from the radiant energy, as required
by the codes and rules of the jurisdiction of installation. 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.
Read all instructions before installing and using the heater.
1.0
The OK3 radiant heaters are suitable for comfort heating use
in non-hazardous areas protected from rain, snow or splashing,
where heating element temperatures in excess of 750°C (1382°F)
will not present the risk of fire or explosion. The heater does
not present a safety hazard when it is installed, operated and
maintained in accordance with these instructions.
2.0
The OK3 heater has two U-shaped metal sheath heating
elements factory interconnected in series or parallel depending
on voltage. Never change heaters which have been factory series
connected to a parallel connection.
3.0
Minimum space clearances from combustibles, when
heaters are horizontally mounted and installed, as listed in Table
1 below.
