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.

8.0 NORMAL SEQUENCE OF OPERATION
8.1
The heater must be properly mounted and wired in accordance
with these instructions, terminal cabinet door closed and secure,
fan blade free, and no obstructions to air inlet or outlet areas.
8.2
Energize the heater at the rated supply voltage.
8.3
Assuming the thermostat is calling for heat OR the thermostat
is turned to a higher temperature than ambient:
8.3.1
The main contactor(s) will energize the elements.
8.3.2
The fan motor will not start immediately.
8.3.3
After a delay of 20-50 seconds, the fan contactor will operate
and the fan will start. See paragraph 3.6 for proper fan rotation.
8.4
After the ambient temperature rises to the operating point of
the thermostat, the thermostat contact will open.
8.4.1
The main contactor(s) will de-energize the elements.
8.4.2
The fan motor will continue to operate, purging the residual
heat from the elements.
8.4.3
After a delay of 20-70 seconds, the fan contactor will open
and the fan will stop.
8.5
The cycle described in 8.3 will repeat.
9.0 MAINTENANCE
The GX unit heater is constructed to operate in tough industrial
applications with a minimum of maintenance.
However, some routine maintenance is recommended to extend
the life of the heater and its components. Always disconnect the
electrical source before performing any maintenance.
9.1
TERMINAL ENCLOSURE - At periodic intervals, of not
more than one year, open the terminal enclosure to inspect for
cleanliness and dampness. Vacuum any dust and wipe up any
moisture. Check all electrical connections and tighten if necessary.
9.2
CONTACTOR(S) - Inspect the contacts carefully and replace
the contactor(s) if excessive wear is becoming evident. Contacts
which are not pitted can be cleaned using a fine grade sandpaper
or emery cloth.
9.3
MOTOR - The motor supplied is rated at 1/3 HP with totally
enclosed construction and sealed ball bearings. These motors are
“permanently”
lubricated by the manufacturer. Internal thermal
protection is provided to eliminate motor overheating. Check all
motor mounts and tighten if necessary.
9.4
FAN BLADE - Visually inspect the fan blade to ensure accidental
damage has not occurred. If bent or damaged, a factory balanced
blade should be installed so that the rated air flow is maintained. A
damaged fan blade may not deliver the required air flow over the
elements, resulting in short cycling of the internal contactors by the
high limit control. This condition will significantly shorten the life of
the contactors. Check to ensure the fan blade is tightly fastened to
the motor shaft.
9.5
HEATER PAINT FINISH - The GX unit heater is finished with
an epoxy paint to provide maximum resistance to corrosion due
to airborne contaminants. We recommend the cabinet be wiped
down periodically using a mild detergent.
8.0 SÉQUENCE NORMALE D’OPÉRATION
8.1
L’appareil doit être installé et raccordé selon les normes
recommandées pour ce type d’appareil, i.e. Porte du boîtier de
contrôle fermée et verrouillée, aucune obstruction à l’entrée et à la
sortie de l’air, et l’éventail non obstrué.
8.2
Mettez l’appareil sous tension (voir la plaque signalétique pour
tension d’opération).
8.3
En assumant que le thermostat ets en position de demande
ou que le point de consigne est plus élevé que la température
ambiante:
8.3.1
Le(s) contacteur(s) principal actionne l’opération des
éléments chauffants.
8.3.2
Le ventilateur ne partira pas immédiatement.
8.3.3
Après un délai de 20-50 secondes, le ventilateur se mettra
en marche. Voir paragraphe 3.6 pour la rotation adéquate du
ventilateur.
8.4
Dès que la température ambiante atteindra le point de consigne
du thermostat, les contacts de celui-ci s’ouvrent.
8.4.1
Le contacteur principal coupe l’opération des éléments
chauffants.
8.4.2
Le ventilateur continue de tourner jusqu’à ce que la chaleur
résiduelle de l’appareil est évacuée.
8.4.3
Après un délai de 20-70 secondes, le ventilateur s’arrêtera.
8.5
Le cycle décrit au paragraphe 8.3 reprendra.
9.0 ENTRETIEN
L’appareil GX est conçu et fabriqué pour les applications
industrielles robustes exigeant une maintenance minime.
Cependant, une maintenance routinière est recommandée
afin d’accroître la durabilité de l’appareil et de ses composants.
Débranchez toujours l’appareil avant de procéder à l’entretien.
9.1
BOÎTIER DE CONTRÔLE - À intervalles réguliers, au moins
une fois par année, ouvrez le boîtler de contrôle pour vous assurer
de la propreté et de l’étanchiété. Débarrassez de toutes poussières
et asséchez si nécessaire. Vérifiez également la fermeté des
connexions électriques.
9.2
CONTACTEUR(S) - Vérifiez les contacts soigneusement et
remplacez s’il y á usure excessive. Sinon, nettoyez les contacts en
utllisant un papier sablé fin ou linge d’émeri.
9.3
MOTEUR - Moteur de 1/3 C.V., Totalement fermé avec
roulement à billes, lubrication permanente par le manufacturier et
protection thermique intégrale. Vérifiez les points de montage et
reserrez si nécessaire.
9.4
ÉVENTAIL - Procédez à une inspection visuelle et assurez
vous que les palles ne sont pas endommagées. Si elles sont pliées
ou endommagées, remplacez par un nouvel éventail balancé
en usine afin d’obtenir le débit d’air spécifique de l’appareil. Un
éventail endommagé peut entrainer une surchauffe de l’appareil
et un cyclage répétitif de la protection haute-limite. Ce cyclage
provoquera l’usure prématurée des contacteurs. Assurez-vous
que l’éventail est ancré solidement à l’arbre du moteur.
9.5
FINI EXTÉRIEUR DE L’APPAREIL - L’appareil GX est
recouvert d’un fini
“epoxy”
pour vous assurer une plus grande
résistance à la corrosion due aux contaminants de l’air. Essuyez
le cabinet de l’appareil avec un détergent doux annuellement.
