IMPORTANT INSTRUCTIONS

When using electrical appliances, basic precautions should always
be followed to reduce the risk of re, electric shock, and injury to
persons, including the following:

1. Read all instructions before using the heater.

2. The heater is hot when in use. To avoid burns, do not let bare

skin touch hot surfaces. The trim around the heater outlet be­comes hot during heater operation. Keep combustible materials,
such as furniture, pillows, bedding, papers, clothes, and curtains
at least 3 ft (0.9 m) from the front of the unit and keep them away
from the sides and rear.

3. Extreme caution is necessary when any heater is used by or
near children or invalids and whenever the unit is left operating

and unattended.

4. Do not operate any heater after it malfunctions. Disconnect

power at the service panel and have the heater inspected by a

reputable electrician before reusing.

5. Do not use outdoors.

6. To disconnect the unit, turn the controls off, and then switch off

at main power supply panel.

7. Do not insert or allow foreign objects to enter any ventilation or
exhaust opening as this may cause an electric shock or re, or
damage to the heater.

8. To prevent a possible re, do not block air intake or exhaust in
any manner.

9. All electrical heaters have hot and arcing or sparking parts in­side. Do not use in areas where gasoline, paint, or ammable
liquids are used or stored.

10. Do not modify this heater. Use it only as described in this man­ual. Any other use not recommended by the manufacturer may

cause re, electric shock or injury to persons.

MAIN SWITCH BEFORE WIRING. ALL WIRING TO BE IN
ACCORDANCE WITH LOCAL AND NATIONAL ELECTRIC
CODES. HEATER MUST BE GROUNDED AS A PRECAUTION
AGAINST ELECTRIC SHOCK.

1. Connect heater only to the voltage and frequency specied on
the nameplate.

2. All wiring to be inaccordance with local codes and National Elec­trical Code.

3. Remove screws securing access door and swing door down to
expose wiring and control compartment.

4. Knockouts are provided at the back of and one side of the heater

⅜ in (35mm) and 1 ⅛ in (29mm), and 1 ⅛ in (29mm) and ⅞ in
(22mm).

5. A ground terminal is provided. The ground wire should be con­nected before making other connections.

6. Rough-in branch circuit wiring to the heater using wire rated for

Installation Instructions

WARNING: Wiring procedures and connections should be in ac-

cordance with the National Electric code (NEC) and local codes.

WARNING: To reduce the risk of re, do not store or use gasoline

or other ammable vapors or liquids in the vicinity of the heater.

CAUTION: High temperature, risk of re, keep electrical cords,

drapery, furnishings, and other combustibles at least 3 ft (0.9 m)
from the front of the heater.

HEATER LOCATION

Unit heaters should be located along outside walls to provide perim­eter air circulation. The discharge air should wipe the walls without

blowing directly on them. (Figure 1)

• Small rooms - can be heated by one or two units. Locate the
unit heater(s) to set up circular air movement within the space.

• Large rooms - requiring multiple unit installations. Units should
be located so that the discharge air from one unit supports the
discharge from another unit and sets up a circular movement.

• Remove Thermostats - should be located on interior walls or

posts away from heat sources, cold drafts, and away from heater
discharge air streams.

MOUNTING UNIT HEATER(S)

CAUTION: Heater must be mounted a minimum of 10 in (25.4

cm) from walls and 6 ft (183 cm) above oor with discharge parallel
to or away from wall.

• Ceiling Mounting - The heater comes equipped with a mount­ing bracket. Fasten to or suspend the heater from the ceiling
using the holes provided in the bracket.

• Wall Mounting - The heater may also be mounted to a wall with

Operation

WARNING: This heater must be properly installed before it

is used.

CONTROLS

• Fan Delay - The heater is equipped with a fan delay con­trol. There will be a short delay to enable the heating ele­ments to warm up before the fan turns on. The fan will
also remain on for a few moments after the elements are

de-energized.

• Automatic High Limit - Each heater is equipped with au­tomatic reset thermal cutouts. Should these safety switch­es operate, they will automatically reset once the element
reaches a safe operation temperature, however, the cause
of the high limit condition should be determined and cor­rected to sure satisfactory operation.

OPTIONAL CONTROLS

• Integral thermostats - All units are available with a built-in
snap-action thermostat. The sensing element is located
in the return air stream to provide accurate temperature
control. The thermostat has a range of 40°F (5°C) (low) to
100°F (38°C) (high). It can be manually operated or ren­dered tamper-proof as desired. This control can be eld­mounted or factory mounted.

• Remote Line Voltage Thermostat - All units can be con-

nected to a line-voltage remote thermostat. A special con­trol terminal block is provided in all units to facilitate easy
connection of the remote thermostat control wiring.

• Remote Low Voltage Thermostat with Relay - A low volt-
age transformer/relay can be eld or factory installed with
the unit for remote low voltage thermostatic control. The
special control terminal block is utilized for this optional

control feature.

• Fan-Only Switch - An optional fan-only switch is available
for integral mounting within the unit. This switch provides
continuous fan-operation, independent of the built-in or
optional remote thermostatic control, which is effective in
eliminating air stratication.

START UP

1. Before the unit is energized, the discharge louvres should
be adjusted for desired air deection.

2. Check to see that all controls and optional accessories are

operation properly.

Maintenance

CAUTION: Before removing the front cover for cleaning,

make certain the power has been turned off at the circuit

breaker panel.

CAUTION: Allow adequate time for the element and body

casing to cool before attempting to work on the heater.

1. Under normal conditions, the heater should be cleaned
once a year. DISCONNECT ALL POWER before cleaning
or servicing the heater.

2. All motors are lubricated for extended life operation, and
will not have to be oiled.
