the jigs and then positioned for the concrete pour. One end
pedestal must be screwed onto rigid wall conduit so that the
mounting height requirements in Figure 1a are met after pouring
of the finished floor. (The method of securing the pedestals and
jigs in place during the pouring of the concrete is at the option of
the installer.) After the concrete has set, remove the jigs from
the pedestals and install the heater as indicated in steps Seven
or Eight.
Installation of Single Unit
Note: For ease of installation, it is important that the sequence
of operations below be followed in order.
1. Remove front cover by removing mounting screws (Fig. 3)
2. Install end caps (must be purchased separately) on both
ends of the heater housing. Refer to Figure 6 for details of
end cap installation.
3. Install leveling nut on each installed pedestal, then position
heater on pedestals. Adjust the leveling nuts until the heater
is level and at the desired mounting height. Then install and
tighten the pedestal lock nuts.
4. Run proper size branch circuit to the junction box through the
appropriate end pedestal.
5. Following the wiring diagram secured to the heater, make
electrical connections.
6. Replace front cover and secure with mounting screws. (See
Figure 3.)
7. If the heater is equipped with a built-in thermostat, adjust the
shaft to the mid-range and let the heater run for a few hours.
If the room temperature is too hot, rotate the shaft counter-
clockwise; if too cool, rotate the shaft clockwise until a com-
fortable temperature is obtained. Let room temperature sta-
bilize after each setting change. The heater will automatical-
ly cycle around this set point on the thermostat.
Note: If a thermostat or disconnect switch is provided in the
heater, these components are accessible through the grille
openings at the left or right end of the heater.
Installation of Multiple Units
Note: For ease of installation, it is important that the sequence
of operations indicated below be followed in order.
1. Remove front cover by removing mounting screws (Figure
3.)
2. Install end caps on the outer end of the first and last heater
(or blank section ) in a run using four No. 6 screws supplied
with end caps. (Refer to Figure 6 for details of end cap
installation.)
3. Run proper size branch circuit to the junction box through
heaters and blank sections (if applicable) on pedestals.
Note: When butting heaters end to end, be sure to position
heaters carefully to insure proper alignment. Leave a 1/16" gap
between heaters to allow for expansion.
4. Adjust the leveling nuts until the heaters are level and at the
desired mounting height. Then install and tighten the
pedestal lock nuts.
Note: 75˚C field wiring may be run through the blank section
wireway.
5. Following the wiring diagram secured to the heater, make the
electrical connections. Refer to Figure 7 to connect the other
heaters in parallel. Grounding of the other heaters is accom-
plished by connecting a jumper wire (not supplied) between
the two adjacent heaters.
6. Replace front covers, and secure with mounting screws.
(Figure 3.)
OPERATION INSTRUCTIONS
1. This heater must be properly installed before it is used.
2. If the heater is equipped with a built-in thermostat, adjust the
shaft to the mid-range and let the heater run for a few hours.
If the room temperature is too hot, rotate the shaft counter-
clockwise; if too cool, rotate the shaft clockwise until a com-
fortable temperature is obtained. Let room temperature sta-
bilize after each setting change. The heater will automatical-
ly cycle around this set point on the thermostat.
Note: If a thermostat or disconnect switch is provided in the
heater, these components are accessible through the grille
openings at the left or right end of the heater.

MAINTENANCE INSTRUCTIONS

For efficient and safe operation and to extend the life of the
heaters, they should be cleaned and inspected for damage at
least annually (preferably at the beginning of the heater season)
or more often in dirty environments. Other than cleaning, your
heaters require no other preventative maintenance.
1. Serious injury or death could result from electric shock.
Make sure electrical power supply circuit(s) coming to
heater is/are disconnected at main disconnect or service
panel before servicing this heater.
before cleaning to prevent a possible burn.
NOTE: More than one power source may enter heater. Be
sure all power is disconnected to heater before cleaning or
servicing.
2. Use care when cleaning element fins to avoid damaging
fins. Note also that fins are sharp and may cause cuts so
avoid contact.
1. The user can perform periodic cleaning of the outer cabinet.
All other servicing is to be done by qualified service personnel.
2. Heater cabinet may be cleaned using a damp cloth to
remove dust that may have accumulated on surfaces. Do not
use harsh cleaners or waxes on surfaces since these could
damage the finish or discolor in use.
4. A vacuum cleaner and/or compressed air may be used to
remove dust and lint that may have accumulated inside
heater around element fins. If heater must be disassembled
for cleaning, use care not to bend or damage the aluminum
fins.
5. After cleaning and servicing, always reassemble replacing
any hardware removed, restore power and check to make
sure the heaters are operating properly
Important Note: There are built-in safety devices provided within
the heaters including one or more over-temperature limit con-
trols (Thermal Protector) - see Wiring Diagram on heater for
specific controls provided. These safety controls are provided to
cycle the heater off to maintain safe temperatures in the event of
a blockage or other abnormal condition. DO NOT remove or
bypass these important safety controls as they are provided to
limit the temperatures and prevent a possible fire in the event
the heater is subjected to an overheating condition. If it is deter-
mined that the heater is cycling off on the safety controls during
normal use, discontinue using the heater until it can be
inspected and repaired by a qualified service personnel.
