INSTRUCTIONS

& PARTS LIST

IMPORTANT: OWNER SHOULD RETAIN THESE INSTRUCTIONS FOR FUTURE REFERENCE

PROPER LOCATION INSTRUCTIONS

Once the total heating load is calculated, the quantity and

capacity of the unit heaters must be determined. because a

large number of low-capacity heaters provides more uniform

heat distribution. This approach is recommended when the

area will be occupied by a relatively large number of seden-

tary personnel, (i.e. working on production lines and at

benches.)

A large number of smaller capacity unit heaters tends to

prevent hot drafts, reduces noise levels, and increases

diversity of load to help reduce electrical demand and

operating costs.

In warehouses where even heat distribution and constant

temperatures are less important, a smaller number of high

capacity units can be used -- in many cases reducing

installation cost. To maintain reasonable heat distribution

and reduce severe stratification even in lower bay areas, the

total air volume of the space should pass through the unit

heaters about three times per hour. (Take total cubic feet

and divide by 20 in order to determine proper total heater

CFM rating.)

It is important that the rated voltage of the heating equip-

ment match the supply voltage. Supply voltage in excess of

the heater rated voltage can damage equipment. Supply

voltage lower than the rated heater voltage will decrease

heater output as well as run the risk of damaging some

components.

Horizontal unit heaters are recommended in low bay areas

with maximum 15 to 18 foot ceilings. These should be

concentrated along outside wall or other areas of greatest

heat loss; spaced to set up a generally circular air move-

ment, each heater supporting the air stream of the other.

Additional vertical down below unit heaters with appropriate

accessory diffusers can be located to counteract ceiling

heat losses (see Figure 1 Location charts).

Figure 1 Location Instructions

GENERAL SAFETY INFORMATION / CAUTION:

Follow all local electrical and safety codes, as well as the

National Electrical Code (NEC) and the Occupational

Safety and Health Act (OSHA).

To avoid possible electrical shock, be sure the electrical

current is turned off at the main switch prior to wiring or

servicing of unit.

If the power disconnect is not integral and is out-of-sight,

lock it in the open position and tag to prevent unexpected

application of power prior to performing any service or

maintenance of the unit.

The unit when installed must be electrically grounded in

accordance with the National Electrical Code and stan-

dard industry practice.

Make certain that the power source conforms to the

requirements of your equipment. See Table 2 on page 6

for wire and circuit size

Check heater voltage and phase on rating label to confirm

that it matches the electric service supply.

Wiring diagrams of the heater and supply connections are

permanently attached to the inside of the heater access

door. All terminals are coded in accordance with the

wiring diagram. Accessory wiring are shown on the unit

wiring diagram and supporting literature.

The heater must be mounted at least 7’ above the floor to

prevent accidental contact with the fan blade which could

cause injury. Install unit so there are no obstructions to the

intake or discharge. Maintain clearances as shown on

Table 1, 2, Fig. 1 & 2.

The wall/ceiling mounting structure and anchoring provi-

sions must be on sufficient strength to support the com-

bined weight of the heater and mounting bracket.

PRINCIPLES OF OPERATION

Upon a call for heat from the floor level or unit mounted

optional accessory thermostat, the unit fan motor and

heating elements shall be energized and remain ON until

temperature reaches setting of thermostat; at which time

the heating elements shall be deenergized.

The fan motor shall continue to run and purge heater

casing of residual heat until setting of fan override is

reached, then the fan motor shall be deenergized.

For those units with a factory installed two speed fan

switch (25-50KW), the unit as shipped from the factory is

set to “low” speed. Customer option to set to “high” speed.

For those units available with subdivided circuits, the

accessory two stage thermostat (optional) will, upon a call

for heat, energize fan motor and the first stage heating

element. Should temperature continue to fall, the thermo-

stat shall energize the second stage heating element.

Upon a rise in space conditions towards setting of the

thermostat, the two stages of heating elements shall be

deenergized in reverse sequence.

The fan motor shall continue to run and purge heater

casing of residual heat until setting of fan override is

reached, then the fan motor shall be deenergized.

The accessory unit mounted stratification thermostat will

energize the unit heater fan motor upon a rise in

temperature above its setting.

When the unit mounted stratification thermostat closes on

a temperature rise and at the same time the floor thermo-

stat calls for heat, the motor shall be energized immedi-

ately and the heating element shall be energized, as

previously described.

The automatic reset safety high limit shall deenergize the

heating elements and control circuits should the tempera-

ture exceed the setting of this device. The fan safety

override shall energize fan motor any time the setting of

this device is exceeded so as to purge heater casing of

excess residual heat.

When the accessory fan switch is placed in the ON position

(for summer air circulation), the unit heater fan motor shall

be energized.

NOTE: The wall thermostat is to be set to the OFF position

during this mode of operation (units with contactors).

For those accessory thermostats equipped with an integral

fan switch, place the switch in the HEAT, or AUTO position

for operation of the fan and elements which shall then be

under control of the thermostat as described above.

When switch is placed in the OFF position, the unit shall be

deenergized. When switch is placed in the FAN position,

elements shall be deenergized and fan shall be immedi-

ately energized.

Optional diffusers lend added air pattern versatility to

individual vertical down blow installations as shown in

above illustations.

MAINTENANCE

CAUTION: Make certain that the power source is disconnected before attempting to service or disassemble any

componet. If the power disconnect is out of the line of sight, lock it in the OPEN position and tag to prevent the

application of power.

ELECTRICAL

Once a year inspect the control panel wiring to make certain insulation is intact and all connections are tight. Inspect

all heater and relay contacts. If the contacts appear badly pitted or burned, replace the contactor / relay.

CLEANING

Clean the unit casing, fan and motor once a year. A dirty motor will tend to run hot and eventually will be damaged

internally. Any rust spots on the casing should be cleaned and repainted.

LUBRICATION

All units up to 20KW have fan motors that are permanently lubricated so that only occasional cleaning is required.

Units above 20KW have fan motors lubricated for 5 years of continuous duty of 10 years of intermittent operations.

When required, remove the oil access plug on back of heater at motor intake grill, open oil cap, fill with S.A.E. No.

INSTRUCTIONS D'ENDROIT NÉCESSAIRES

Dès que la charge totale de chauffage est calculée, la

quantité et la capacité des chauffages d'unité doivent être

déterminés. parce qu'un grand nombre de chauffages de

capacité basse fournit la distribution de chaleur plus

uniforme. Cette approche est recommandée quand la région

sera occupée par un relativement grand nombre de person-

nel sédentaire, (c'est-à-dire travaillant des chaînes de

fabrication et aux bancs.)

Un grand nombre de plus petits chauffages d'unité de

capacité a tendance à prévenir des brouillons chauds, réduit

des niveaux bruyants et augmente la diversité de charge

pour aider à réduire la demande électrique et les frais

d'exploitation.

Dans les magasins où chauffent même la distribution et les

températures constantes sont moins importants, un plus

petit nombre de hautes unités de capacité peut être utilisé -

dans beaucoup de cas réduisant le prix d'installation. Pour

maintenir la distribution de chaleur raisonnable et réduire la

stratification sévère même dans les régions de baie plus

basses, le volume aérien total de l'espace devrait traverser

les chauffages d'unité environ trois fois par heure. (Prenez

des pieds cubiques totaux et la division par 20 déterminent

afin du chauffage total nécessaire l'estimation de CFM.)

Il est important que le voltage évalué de l'équipement

chauffant correspond au voltage de réserves. Le voltage de

réserves plus du voltage estimé du chauffage peut nuire à

l'équipement. Le voltage de réserves plus bas que le voltage

de chauffage évalué diminuera la production de chauffage

aussi bien que courra le risque de nuire à quelques

composantes.

Les chauffages d'unité horizontaux sont recommandés dans

les régions de baie basses avec les plafonds de 15 à 18

pieds maximums. Ceux-ci devraient être concentrés le long

du mur extérieur ou d'autres régions de la plus grande perte

de chaleur; espacé monter un mouvement aérien

généralement circulaire, chaque chauffage soutenant le

courant atmosphérique de l'autre. Supplémentaire vertical en

bas au-dessous des chauffages d'unité avec diffusers

auxiliaire approprié peut être trouvé pour contrer des pertes

de chaleur de plafond (voir le chiffre 1 des graphiques

d'Endroit).

Instructions d'Endroit du chiffre 1

Général SAFETY INFORMATION / PRUDENCE :

Suivez tout l'habitant d'origine électrique et les codes de

sécurité, aussi bien que le Code Électrique national (NEC) et

l'acte de Santé et de Sécurité du Métier (OSHA).

Pour éviter le choc électrique possible, soyez sûrs que le

courant électrique est éteint au changement principal avant

de télégraphier ou assurer l'entretien de l'unité.

Si le pouvoir débranche n'est pas intrinsèque et est hors de

vue, la serrure cela dans la position ouverte et l'étiquette pour

prévenir l'application inattendue de pouvoir avant d'exécuter

n'importe quel service ou maintenance de l'unité.

L'unité quand installé doit être électriquement fondée

conformément à la pratique d'industrie Codée et standard

Électrique nationale

Vérifiez que la source de pouvoir conforme aux exigences de

votre équipement. Voir la Table 2 sur la page 6 pour la

grandeur de circuit et le fil

Vérifiez le voltage de chauffage et la phase en estimation de

l'étiquette pour confirmer qu'il correspond aux réserves de

service électriques.

INSTRUCTIONS

& PARTS LIST

IMPORTANT: OWNER SHOULD RETAIN THESE INSTRUCTIONS FOR FUTURE REFERENCE

55 THRU 100 kW MODELS

PROPER LOCATION INSTRUCTIONS

Once the total heating load is calculated, the quantity and

capacity of the unit heaters must be determined. because

a large number of low-capacity heaters provides more

uniform heat distribution. This approach is recommended

when the area will be occupied by a relatively large

number of sedentary personnel, (i.e. working on produc-

tion lines and at benches.)

A large number of smaller capacity unit heaters tends to

prevent hot drafts, reduces noise levels, and increases

diversity of load to help reduce electrical demand and

operating costs.

In warehouses where even heat distribution and constant

temperatures are less important, a smaller number of high

capacity units can be used -- in many cases reducing

installation cost. To maintain reasonable heat distribution

and reduce severe stratification even in lower bay areas, the

total air volume of the space should pass through the unit

heaters about three times per hour. (Take total cubic feet

and divide by 20 in order to determine proper total heater

CFM rating.)

It is important that the rated voltage of the heating equip-

ment match the supply voltage. Supply voltage in excess

of the heater rated voltage can damage equipment.

Supply voltage lower than the rated heater voltage will

decrease heater output as well as run the risk of damag-

ing some components.

Horizontal unit heaters are recommended in low bay

areas with maximum 15 to 18 foot ceilings. These should

be concentrated along outside wall or other areas of

greatest heat loss; spaced to set up a generally circular air

movement, each heater supporting the air stream of the

other. Additional vertical down below unit heaters with

appropriate accessory diffusers can be located to counter-

act ceiling heat losses (see Figure 1 Location charts).

Figure 1 Location Instructions

GENERAL SAFETY INFORMATION / CAUTION:

Follow all local electrical and safety codes, as well as the

National Electrical Code (NEC) and the Occupational

Safety and Health Act (OSHA).

To avoid possible electrical shock, be sure the electrical

current is turned off at the main switch prior to wiring or

servicing of unit.

If the power disconnect is not integral and is out-of-sight,

lock it in the open position and tag to prevent unexpected

application of power prior to performing any service or

maintenance of the unit.

The unit when installed must be electrically grounded in

accordance with the National Electrical Code and stan-

dard industry practice.

Make certain that the power source conforms to the

requirements of your equipment. See Table 2 on page 6

for wire and circuit size

Check heater voltage and phase on rating label to confirm

that it matches the electric service supply.

Wiring diagrams of the heater and supply connections are

permanently attached to the inside of the heater access

door. All terminals are coded in accordance with the

wiring diagram. Accessory wiring are shown on the unit

wiring diagram and supporting literature.

The heater must be mounted at least 7’ above the floor to

prevent accidental contact with the fan blade which could

cause injury. Install unit so there are no obstructions to the

intake or discharge. Maintain clearances as shown on

Table 1, 2, Fig. 1 & 2.

The wall/ceiling mounting structure and anchoring

provisions must be on sufficient strength to support the

combined weight of the heater and mounting bracket.

PRINCIPLES OF OPERATION

Upon a call for heat from the floor level or unit mounted

optional accessory thermostat, the unit fan motor and

heating elements shall be energized and remain ON until

temperature reaches setting of thermostat; at which time

the heating elements shall be deenergized.

The fan motor shall continue to run and purge heater

casing of residual heat until setting of fan override is

reached, then the fan motor shall be deenergized.

All units are supplied with a single speed motor .The 55-75

kW heaters are supplied with 3 stages of heat. The heater

can be wired as one stage, two stage or three stage. The

80 thru 100 kW models are supplied with four stages and

be operated as 1 thru 4 stages.The thermostat or step

controller(optional) will, upon a call for heat, energize fan

motor and the first stage heating element. Should tempera-

ture continue to fall, the thermostat shall energize the

remaining stages according to demand.

Upon a rise in space conditions towards setting of the

thermostat or step controller, the stages of heating ele-

ments shall be deenergized in reverse sequence.

The fan motor shall continue to run and purge heater

casing of residual heat until setting of fan override is

reached, then the fan motor shall be deenergized.

The accessory unit mounted stratification thermostat will

energize the unit heater fan motor upon a rise in

temperature above its setting.

When the unit mounted stratification thermostat closes on a

temperature rise and at the same time the floor thermostat

calls for heat, the motor shall be energized immediately and

the heating element shall be energized, as previously

described.

The manual reset safety high limit shall deenergize the

heating elements and control circuits should the temperature

exceed the setting of this device. The fan safety override

shall energize fan motor any time the setting of this device is

exceeded so as to purge heater casing of excess residual

heat.

When the accessory fan switch is placed in the ON position

(for summer air circulation), the unit heater fan motor shall

be energized.

NOTE: The wall thermostat is to be set to the OFF position

during this mode of operation (units with contactors).

For those accessory thermostats equipped with an integral

fan switch, place the switch in the HEAT, or AUTO position

for operation of the fan and elements which shall then be

under control of the thermostat as described above.

When switch is placed in the OFF position, the unit shall be

deenergized. When switch is placed in the FAN position,

elements shall be deenergized and fan shall be immedi-

ately energized.

Optional diffusers lend added air pattern versatility to

individual vertical down blow installations as shown in

above illustations.

MAINTENANCE

CAUTION: Make certain that the power source is disconnected before attempting to service or disassemble any

componet. If the power disconnect is out of the line of sight, lock it in the OPEN position and tag to prevent the

application of power.

ELECTRICAL

Once a year inspect the control panel wiring to make certain insulation is intact and all connections are tight. Inspect

all heater and relay contacts. If the contacts appear badly pitted or burned, replace the contactor / relay.

CLEANING

Clean the unit casing, fan and motor once a year. A dirty motor will tend to run hot and eventually will be damaged

internally. Any rust spots on the casing should be cleaned and repainted.

LUBRICATION

All units have fan motors that are permanently lubricated so that only occasional cleaning is required.

Necessaires de thermostat incorpores T5100, T5102, T5122, TC5102 et TC5103 (pour etre installes sur place

les radiateurs de series 5100)

Le T5100, Unipolaire a une direction (SPST), controle la tension de ligne pour les radiateurs monophases jusqu' a

277V, 25A.

o u

veilleuse (24-277 volts) pour les radiateurs munis de contacteurs.

Le T5102, bipolaire controle la tension de ligne interrompant tous les conducteurs non mis a la terre pour les

radiateurs monophases jusqu' a 277V, 25A

o u

bipolaire a une direction pour les radiateurs tripolaires jusqu' a 240V, 25A mais n' interrompant pas tous

les conducteurs non mis a la terre pour les applications triphasees.

Le T5122, a un controle basse tension (24V) a 2 etages pour radiateur a 2 etages. Les deux circuits sont separes

et controles par le meme element sensitif. Les interrupteurs controlant ces circuits sont calibres pour

ouvrir et fermer en serie.

Le TC5102 est un relais/thermostat qui est utilise avec des radiateurs de 480 & 600 volts pour controler le moteur

du ventilateur. Il sert a detecter l arrivee de la chaleur (therm.de strat.) au plafond et a faire demarrer

le moteur du ventilateur pour faire recirculer accumulation de chaleur.

Le TC5103 sert a controler le moteur du ventilateur sur les radiateurs de 208, 240 & 277 volts pour faire recirculer

la chaleur stratifiee accumulee au plafond.

Lisez S.V.P. chaque instruction d'installation soigneusement avant de commencer l'installation.

1.) ATTENTION:

Afin d'eviter un choc electrique possible, mettez le radiateur a la position ARRET au niveau du panneau de

distribution. Sur les radiateurs equippes d'un interrupteur de courant, mettez l'interrupteur a la position ARRET.

2.) Desserez les deux vis situees sur la porte du panneau de controle et laissez celle-ci pendre. Quelques modeles

ont un dispositif d'arret supplementaire. Comprimez ce dispositif afin qu il s'ouvre.

3.) Enlevez la rondelle defoncable de dia. 1

2" (13mm) alimentant l'ampoule du thermostat Fig. 1 afin de connecter

celle-ci par le trou ainsi fait.

ATTENTION: Gardez le tube capillaire loin des dispositifs et des fils electriques internes.

4.) Enlevez lez 2 petites rondelles defoncables pour les attaches des ampoules du thermostat a l'arriere du radiateur,

(voir Fig. 1.) Inserez les deux attaches fournies. Agrafez les ampoules sur les attaches.

5.) Enlevez le papier du dos de l'etiquette (fournie). Alignez l'etiquette sur le trou de l'arbre du thermostat et

positionnez-la (voir Fig. 1.) Collez l'ettiquette sur le cote du radiateur comme montre.

6.) Notez l'orientation de la patte sur le support du thermostat. (voir Fig. 1). Positionnez-la comme montre seulement.

Installez le thermostat avec les 2 vis de montage No. 8 fournies.
