WARNING
WHENEVER HAZARDOUS MATERIALS ARE
PRESENT, ENSURE THAT THE TERMINAL
HOUSING COVERS, PLUGS, ETC., ARE
SECURED (BUT NOT OVER-TIGHTENED)
BEFORE ENERGIZING THE HEATER.
CAUTION
ALL CIRCUITS MUST BE IN THE OPEN
POSITION BEFORE REMOVING JUNCTION
OR TERMINAL BOX COVERS.
CAUTION
USE SUPPLY WIRES SUITABLE FOR 221°F
(105°C). SUPPLY WIRES ARE TO BE FUSED
WITH APPROPRIATELY SIZED HRC FUSING.
WARNING
USE APPROVED CONDUIT AND CONDUIT
SEALS AS REQUIRED BY HAZARDOUS
LOCATION STANDARDS.
CAUTION
ENSURE THAT NO POWER IS CONNECTED
TO THE EQUIPMENT PRIOR TO MAKING
ANY CONNECTIONS.
9.0 START-UP
9.1 For heaters with a tamper-proof thermostat,
to set temperature, disconnect the power and
remove the socket head cap screw. Set the
thermostat to the desired room temperature
with a screw driver and replace cap screw.
9.2 For heaters with an externally adjustable
thermostat, set thermostat to desired
temperature by adjusting the dial.
NOTE: The thermostat temperature range is 0° -
100°F (-18° - 40°C) with an operating differential of
5 - 7°F (3 - 4°C).
9.3 Install the terminal box cover and tighten
securely.
9.4 Check to ensure that all plugs, screws, and
covers are securely in place.
9.5 Check associated electrical equipment.
9.6 Check that all wall/floor mounting bracket
connections are tight.
9.7 Turn on the supply power.
WARNING
TO PREVENT UNSAFE OPERATION OF THE
HEATER DO NOT EXCEED THE MAXIMUM
ALLOWABLE AMBIENT OPERATING
TEMPERATURE OF 104°F (40°C).
10.0 MAINTENANCE
10.1 Periodically inspect the heater installation to
ensure that all connections, fittings, plugs,
screws, covers, etc. are tight and free of
corrosion.
10.2 Check that the reflector baffles (if required)
have not moved upwards or downwards in
relation to the heat sink.
10.3 Check the extrusions of the heater for dust
and debris. A blast of compressed air is
recommended for cleaning the heat sink. If air
is not available, disconnect the power supply
to the heater and when cool, wipe it down
with a damp cloth or soft brush. Remove wire
guards prior to cleaning.
WARNING
DISCONNECT POWER FROM THE
HEATER BEFORE PERFORMING ANY
MAINTENANCE. FAILURE TO DO SO CAN
RESULT IN PROPERTY DAMAGE, INJURY
OR DEATH.
CAUTION
DO NOT USE WATER TO CLEAN HEATER.
10.4 The heat sink is anodized or painted black
to ensure that the maximum area code
temperature is not exceeded. After an
extended period of use or in extremely harsh
environments the anodization/paint may wear
away leaving bare surfaces. For continued
safe operation, these surfaces must be
repainted. When repainting use only black
high temperature resistant paint.
10.5 Except for thermostat replacement, field repair
of the heater shall not be normally undertaken.
In the event that the heater must be repaired,
contact the factory for a return authorization
number.
