15) Use this heater only as described in this manual. Any other use not recommended by
the manufacturer may cause fire, electric shock, or injury to persons.
16) Always plug heater directly into a wall outlet/receptacle. Never use with a re-locatable
power tap (outlet/power strip).
17) This heater includes a visual alarm to warn that parts of the heater are getting
excessively hot. If the alarm light goes on, immediately turn the heater off and inspect
for any objects on or adjacent to the heater that may cause high temperatures. DO
NOT OPERATE THE HEATER WITH THE ALARM LIGHT ON.
18) SAVE THESE INSTRUCTIONS
.
a) Power connections
WARNING! ELECTRIC SHOCK HAZARD. All power connections must be
connected or guarded. Failure to do so will expose operators to
possible shock and the possibility of grounding-out or shorting-out of
the test power source.
b) Control power
Use 120V type S or type SJ jacketed cord to a wall connection. Cord and service
rated to 15 AMP minimum.
c) Air intakes and exhaust ports
Caution!
All air intakes and exhaust ports must be clear and fully open.
This
heater has one air intake designed for proper air flow. Reducing or blocking
air flow will lead to overheating and heater failure.
High volumes of cooling air are needed to prevent load elements from overheating. By
their very nature, resistors under load convert electrical energy to heat. This heat must be
removed from the unit. The blower, intake, and exhaust ports are sized to provide the
proper amount of cooling air. Preventing or limiting air flow will allow the heater to
overheat.
To increase the life of the load elements, allow the fans to run at least three minutes after
the load is removed or until exhaust air is cool.
No ductwork is permitted on intake or exhaust of this heater as this will cause a
backpressure and ruin the resistors.
Caution!
Material can be moved by intake air or exhaust air.
Failure to secure
material could cause injury to bystanders or damage to the heater.
