MAINTENANCE
Disconnect all power before installing
or servicing the heater. Failure to do
so could result in personal injury and/
or property damage. All maintenance
and installation should be done by
qualified personnel in compliance with
local codes.
13.0 As a safety precaution and to avoid non-scheduled
downtimes, replace the heating element if a pronounced hot spot
(area of the element that glows brighter) is visible along its heated
section.
After performing maintenance, and
prior to energization, an insulation
resistance check must be performed.
Heater with values less than 1 M should
follow a drying process. Please contact
factory for details on procedure if
heater is under 1 MΩ Ω Ω Ω Ω .
10.0 To maximize heating efficiency, periodically wipe clean the
reflector with a cloth dampened with alcohol.
OPERATION
Prior to operation, an insulation
resistance check must be performed.
Heater with values less than 1 MΩ Ω Ω Ω Ω
should follow a drying process. Please
contact factory for details on procedure
if heater is under 1 MΩ Ω Ω Ω Ω.
11.0 Heaters that have not been energized for a prolonged period
shall be restarted under close supervision for the first thirty minutes
of operation.
12.0 Energize the heater at the voltage shown on the nameplate
and visually check the element to ensure that it slides freely on
expansion.

INSTALLATION, OPERATION AND MAINTENANCE INSTRUCTIONS FOR
SERIES OK3 – INFRARED RADIANT HEATERS
FIRE/EXPLOSION HAZARD 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
1.0 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
following.

Min. Spacing
From nearest wall 600 mm (24”)
From the ceiling 300 mm (12”)
INSTALLATION
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°C). 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.
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.
