AIR HEATING FROM THE SAME VERSATILE UNIT
These heavy-duty heaters provide spot heating for hard to
heat areas, or they can be used as the primary source of heat
for areas not reached by an existing heating system.
The fan and motor are carefully matched to insure quiet, trou-
ble-free operation and fan blades are precision balanced be-
fore installation.
Heaters in all capacities (3, 5, 7½, 10 or 12kw) have the same
dimensions, and use the same mounting brackets. All compo-
nents and controls, including thermostat, transformers, relays,
and switches are enclosed inside the case. Wiring is simple
and all heaters can operate from a single power source.
Installation Instructions
IMPORTANT INSTRUCTIONS
When using electrical appliances, basic precautions should al-
ways be followed to reduce the risk of fire, electric shock and
injury to person, including the following:
1. Read all instructions before using this heater.
2.
A heater has hot and arcing or sparking parts inside. Do
not use it in areas where gasoline, paint or flammable liq-
uids are used or stored.
3.
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 com-
bustible materials, such as furniture, pillows, bedding, pa-
pers, clothes, etc. and curtains at least 3 ft. (0.9m) from
the front of the heater.
4.
Extreme caution is necessary when any heater is used by
or near children or invalids and whenever the unit is left
operating and unattended.
5.
Do not operate any heater after it malfunctions. Discon-
nect power at the service panel and have the heater in-
spected by a reputable electrician before reusing.
6.
Do not use outdoors.
7.
To disconnect the unit, turn the controls off, and trun off
power to heater circuit at main disconnect panel.
8.
Do not insert or allow foreign objects to enter any venti-
lation or exhaust opening as this may cause an electric
shock or fire, or damage to the heater.
9. To prevent a possible fire, do not block air intake or ex-
haust in any manner.
10.
Do not modify this heater. Use it only as described in this
manual. Any other use not recommended by the manufac-
turer may cause fire, electric shock or injury to persons.
SAVE THESE INSTRUCTIONS
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 provide 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 provides a
circular air movement.
•
Remote thermostats
- should be located on interior walls
or posts away from heat sources, cold drafts, and away
from heater discharge streams.
MOUNTING UNIT HEATER(S)
CAUTION:
Heater must be mounted a minimum of 10 in.
(25.4cm) from walls and 6 ft (183 cm) above floor (8 ft (244
cm) for vertical air flow) with the discharge parallel to or away
from wall.
•
MOUNTING BRACKET
- The heater is shipped with a
mounting bracket packed separately in the carton. Secure
the bracket to threaded attachment points on the sides of
the heater with two bolts (provided). Select desired angle
of tilt (Horizontal, 15, 30, 45, 60, 75, or Vertical), remove
corresponding knockouts on sides of the heater, then
screw the remaining two bolts into the threaded holes in
the bracket so that the bolts pass through the knockout
holes. The unit is now ready for hanging.
•
CEILING MOUNTING
- Fasten the heater securely to the
ceiling using the center hole in the bracket or the two holes
on either side of the center hole. The Unit mounting bracket
may be attached directly to the ceiling.
•
WALL MOUNTING
- The heater may also be mounted to a
wall with accessory wall bracket, Part # EUHWB. The wall
bracket attaches to the center hole of the unit mounting
bracket.
