WARNING
WARNING. For metal sheathed heaters, 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.
3. When mounting, maintain a minimum clearance to
combustibles of 15” (381 mm) at sides, 10”(254 mm) at top
and 12” (305 mm) at ends.

INSTALLATION, OPERATION AND MAINTENANCE INSTRUCTIONS FOR
SERIES OKA – 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 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.
2.0 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.
3.0 To avoid damage in transit, heaters with quartz lamp or
quartz tube elements are shipped with the elements not installed in
the fixture.
4.0 A minimum of handling of the quartz sheath is
recommended since any type of contamination on the sheath may
reduce service life.
5.0 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.
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.
6.0 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.
7.0 For metal sheathed heaters, install proper ground fault
protection to prevent personal injury and/or property damage.
For metal sheathed heaters, 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.
8.0 When mounting, maintain a minimum clearance to combustibles
of 15”(381 mm) at sides, 10”(254 mm) at top and 12”(305 mm) at ends.
Heaters with quartz tube or quartz lamp
type heating elements are suitable for
horizontal mounting only. Heaters with
metal sheathed heating elements can
be mounted in any desired position.
9.0 For short circuit protection, heaters must be installed with
proper fast acting fuses or breakers as close as possible to the
amperage draw of the unit(s), in compliance with the local electrical
codes.

WARNING
WARNING. Heaters with quartz tube or quartz lamp
type heating elements are suitable for horizontal
mounting only. Heaters with metal sheathed heating
elements can be mounted in any desired position.
4. For short circuit protection, heaters must be installed with
proper fast acting fuses or breakers as close as possible
to the amperage draw of the unit(s), in compliance with the
local electrical codes.
5. Two sliding mounting pads are provided with each heater.
6. The mounting pads have a ¼”-20 tapped hole which
can be utilized to attach the heater to a suitable non-
combustible support positioned as in paragraph 2 of
Section B. Installation.

10.0 Two sliding mounting pads are provided with each heater.
The mounting pads have a ¼”-20 tapped hole which can be utilized to
attach the heater to a suitable non-combustible support positioned as
in paragraph 7.0.
OPERATION
For metal sheathed heaters, prior to
operation an insulation resistance
check must be performed. Heater with
values less than 1 M
Ω Ω Ω Ω Ω
should follow a
drying process. Please contact factory
for details on procedure if heater is
under 1 M
Ω Ω
Ω Ω Ω .
15.0 Energize the heater at the voltage shown on the nameplate
and visually check the element to ensure that it slides freely on
expansion. A small sag is normal, especially on longer heaters.
16.0 Heaters with metal sheathed elements which have not been
energized for a prolonged period shall be restarted under close
supervision for the first thirty minutes of operation.

11.0 The connection boxes at the ends of the heater each have a
volume of 12 in³(196 cm³).
12.0 Heater is provided with 15” long pig tail lead wires suitable for
200°C that must be terminated in a remote junction box. Supply
connectors into the remote junction box must be suitable for
194°F(90°C), or, alternately the heater may be wired with 200°C supply
wire. The ground wire from the supply shall be connected to the
grounding connection located in the box at one end of the heater.
13.0 To facilitate wiring, a ½” NPT tapped hole is provided at each
end of the heater extrusion. A duplex conduit connector or T type
junction box attached to either mounting hole will simplify wiring of
single or multiple units. For type R heaters, which have both terminals
at one end in a moisture resistant housing, use rigid conduit to ensure
moisture protection.
14.0 Follow this procedure and Fig. 3 when installing the quartz
tube or lamp:
14.1 Disconnect power at source.
14.2 Remove the terminal covers at each end of the heater.
14.3 Remove the keeper screw on one retainer bracket and slide
the ceramic element holder aside.
14.4 Feed the element lead wire through the hole in the ceramic
holder at the fixed end first. Slide the ceramic holder removed in 14.3
over the element so that the element is captured in both ceramic
holders and then reinstall the keeper screw.
14.5 Loosen the electrical terminal nut on the ceramic blocks to
permit connection of the power and lead wires.
14.6 To connect the element lead wires, slide the ceramic 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
with element thermal expansion and the
taut lead wires help to
secure the element in place.
14.7 Connect the power wires to the electrical terminals and install
terminal covers.
14.8 Before energizing, wipe the quartz sheath and reflector with
a cloth or paper towel dampened with alcohol.
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.
17.0 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.
For metal sheathed heaters, after
performing maintenance, and prior to
energization, an insulation resistance
check must be performed. Heater with
values less than 1 M
