3.7 MOTOR ROTATION - IMPORTANT. Three phase heaters are
supplied with motors of corresponding phase. The proper motor/fan
rotation, viewed from the rear of the heater is counter clockwise,
incorrect rotation of the fan will cause the heater to overheat and
cycle on the high limit. To reverse the fan rotation, interchange two
supply voltage conductors connected to lugs L1, L2.
3.8 The schematic wiring diagram in Fig. 5 illustrates the GX unit
heater with contactor, transformer and thermostat. Some of this
equipment is optional and may not be included with your GX heater.
4.0 TEMPERATURE CONTROL
4.1 BUILT-IN THERMOSTAT - heaters with a factory installed
thermostat have all other standard controls such as contactors,
and transformers factory installed and prewired.
4.2 THERMOSTAT KIT FAT-8A - (Field installed) Install the FAT-8A
thermostat kit in accordance with the instruction sheet provided.
4.3 REMOTE LINE VOLTAGE THERMOSTAT - A remote
thermostat rated to operate as a pilot duty, inductive device on
240V is required. For proper installation and wiring of the selected
thermostat, refer to the manufacturer’s instructions. CCI Thermal
Technologies can supply appropriate thermostats.
4.4 REMOTE LOW VOLTAGE THERMOSTATS - The GX heater
can be provided with a low voltage control internally wired for
remote connection to 24V thermostats. Ensure that this control
option is installed in the GX heater before energizing a low voltage
thermostat from the heater. For proper installation and wiring of the
selected thermostat, refer to the manufacturer’s instructions. CCI
Thermal Technologies can supply low voltage thermostats for use
with GX heaters.
5.0 “FAN ONLY” FEATURE (Summer Switch)
The “fan only” feature will allow the heater to cycle in a “heat”
mode dictated by the controlling thermostat, even though the fan is
operating continuously.
5.1 Terminals are provided for remote mount of a S.P.S.T. “fan only”
switch, rated 240V 60Hz. A jumper across terminals “T2” and “T3”
is installed at the factory, and must be removed and substituted
with the remote switch leads if this feature is to be available. See
Fig. 5.
5.2 A “fan only” switch may be factory installed (optional extra)
directly in the heater.
6.0 FAN DELAY
All GX unit heaters incorporate a fan delay feature in both the “ON”
and “OFF” cycles. This is a desirable feature allowing the heater
to come to temperature before the fan operates (no cold blasts)
and to cool down in the “OFF” cycle (longer life for the control
components and motor). Delay “ON” is 20-50 seconds and delay
“OFF” is 20-70 seconds.
7.0 REMOTE ENERGY MANAGEMENT CONTROL
Remote energy management control is standard on 40 and 50kW
units. Internal power to contactor coil C2 may be interrupted and
controlled remotely by removing the jumper between terminals
“T2” and “T3”, and then connecting a passive contactor in its place.
A closed contact will allow 100% heating capacity and an open
contact will allow 50% heating capacity. See schematic wiring
diagram Fig. 5.
3.7 ROTATION DU MOTEUR - IMPORTANT. Sur tous les appareils
triphasés, les moteurs sont également triphasés. Vue de l’arrière
de l’appareil, la rotation normale de l’éventail est dans le sens
anti-horaire. Une rotation inversée entrainera l’arrêt de l’appareil
par la haute-limite. Pour corriger la rotation, interchangez deux ls
d’alimentation sur les cosses L1, L2.
3.8 Le schéme de la Fig. 5 illustre un appareil GX muni d’un
contacteur, transformateur et thermostat. Cet équipement est
facultatif et peut ne pas être inclus dans votre appareil.
4.0 CONTRÔLE DE TEMPÉRATURE
4.1 THERMOSTAT INTÉGRÉ - Les appareils avec thermostat
intégré possède tous les autres contrôles tels que contacteur et
transformateur et sont prélés en usine.
4.2 TROUSSE DE THERMOSTAT FAT -8A - (Pour installation
en chantier) Installez le thermostat FAT-8A selon les instructions
fournies avec cette trousse.
4.3 THERMOSTAT À TENSION SECTEUR À DISTANCE - Un
thermostat à distance, adéquat pour circuit de commande et appareil
inductif à 240V ets requis. Voir les instructions du manufacturier
pour une installation adéquate. CCI Thermal Technologies
possède en magasin une gamme variée de thermostats.
4.4 THERMOSTAT À BASSE TENSION À DISTANCE - L’appareil
GX peut intégré les contrôles requis pour le raccordement à
distance d’un thermostat à 24V. Assurez-vous que ce dispositif
facultatif est intégré à l’appareil GX avant d’opérer un thermostat
à basse tension à partir de l’appareil. Voir les instructions du
manufacturier pour une installation adéquate. CCI Thermal
Technologies possèdent une gamme variée de thermostats à
basse tension.
5.0 COMMANDE DU VENTILATEUR (Interrupteur Estival)
Cette caractéristique permet à l’appareil de répondre à l’appel de
chauffage, même si l’éventail est en opération continue.
5.1 Un bornier est prévu pour l’installation à distance d’un
interrupteur du ventilateur (U.P.U.D.), 240V 60Hz. Un cavalier
est instalé en usine entre les bornes T2 et T3, lequel sera
enlevé et substitué par les ls de l’interrupteur à distance si cette
caractéristique doit être disponible. Voir Fig. 5.
5.2 Un interrupteur du ventilateur est disponible pour l’installation
intégrée en usine (facultatif moyennant un suppliment).
6.0 COMMANDE À RETARDEMENT DU VENTILATEUR
Tous les appareils GX sont munis d’une commande à retardement
du ventilateur pour la mise en marche et l’arrêt. Cette caractéristique
unique évite la projection d’air froid au démarrage et la surchauffe
à l’arrêt, d’où une meilleure durabilité des composants de contrôles
et du moteur. Le délai de mise en “marche” est de 20-50 secondes
et le délai “d’arrêt” est de 20-70 secondes.
7.0 RÉGUALTEUR CENTRAL D’ÉNERGIE À DISTANCE
Des borniers intégrés à tous les appareils de 40 et 50kW permettent
d’interrompre la puissance au contacteur C2. En enlevant le
cavalier T2, T3 à bobine du contacteur C2 et en le substituant par
un contact passif, vous réduirez do 50% la capacité de l’appareil
selon le signal de la position ouverte ou fermée commandée par le
régulateur central d’énergie à distance. Voir schéma Fig. 5.

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

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 ne 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 ow is maintained. A
damaged fan blade may not deliver the required air ow over the
elements, resulting in short cycling of the internal contactors by the
high limit control. This condition will signicantly 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 nished 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.
