4) Sa ety
This heater is designed for a variety of loads. Because of this, it is possible that voltages
higher that those applied can be present inside the heater and at external connections of
the heater. Work on the heater’s internal systems should only be attempted by highly
trained technicians and only when power has been disconnected and cannot be
reconnected to the unit.
IMPORTANT INSTRUCTIONS
When using electrical appliances, basic precautions should always be followed to reduce
the risk of fire, electrical shock, and injury to persons, including the following:
1) Read all instructions before using this heater.
2) This heater is hot when in use. To avoid burns, do not let bare skin touch hot
surfaces. Use handles when moving this heater. Keep combustible materials, such
as furniture, pillows, bedding, papers, clothes, and curtains at least 6 feet
(1.8 meters) from the exhaust of the heater 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 heater is left operating and unattended.
4) Remove all animals and plants from area to be heated
5) Always unplug heater when not in use.
6) Do not operate any heater with a damaged cord or plug or after the heater
malfunctions or has been dropped or damaged in any manner. Discard heater or
return to authorized service facility for examination and/or repair.
7) Do not use outdoors.
8) Do not use in wet or moist locations
9) This heater is not intended for use in wet indoor environments.
10) Do not run cords under carpeting. Do not cover cords with throw rugs, runners, or
similar coverings. Do not route cords under furniture or appliances. Arrange cords
away from traffic areas and where it will not be tripped over.
11) To disconnect heater, turn controls off, then remove plugs from outlets.
12) Do not insert or allow foreign objects to enter any ventilation or exhaust opening as
this may cause an electric shock or fire, or damage the heater.
13) To prevent a possible fire, do not block air intakes or exhaust in any manner. Do not
use on soft surfaces, like a bed, where openings may become blocked.
14) A heater has hot and arcing or sparking parts inside. Do not use it in areas where
gasoline, paint, or flammable liquids are used or stored.

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 O ERATE 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 o grounding-out or shorting-out o
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 AM minimum.
c) Air intakes and exhaust ports
Caution! All air intakes and exhaust ports must be clear and ully 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. reventing 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.

Good air flow keeps the heater cool but can very easily move light debris such as paper,
cardboard, and dust with great velocity. Loose materials around the heater, especially
near the intake and exhaust, must be secured to prevent movement. Material on the
exhaust side may be blown into and injure a bystander. Material near the intake may be
taken into the heater damaging internal components.
d) Exhaust temperature
WARNING! FIRE AND BURN HAZARD. Keep lammable material at least 40 eet
away rom the heater. A great deal o heat is expelled rom the heater.
Temperatures inside the heater are su icient to ignite lammable
umes or materials. Failure to maintain proper housekeeping and
properly securing lammable material could lead to ire, burns, and/or
injury.
Even with sufficient air flow, internal component temperature will exceed 400 °F. Exhaust
air temperature rise of 100 °F can be achieved at full power. Flammable materials must
not be kept around the heater. Heat from the heater could ignite this material.
e) Connecting and disconnecting
WARNING! BURN HAZARD. Attempting to connect or disconnect leads while
heater is in operation can lead to severe injury or death. Connecting or
disconnecting plugs and receptacles while current is lowing or
voltage is present may cause arcing. Arcing can generate a great deal
o light, heat and possibility o electrocution.

5) Operation
a) Pre-startup
1. Check housekeeping in the operational area and correct all unsafe conditions.
Failure to do this may result in debris being blown around and may cause a fire hazard.
2. osition heater so that air will flow freely into the intakes and out of the exhaust port.
3. All air intakes and exhaust ports must be clear of any blockages or debris.
4. For best results it is recommended that all doors, window, vents, and air conditioners in
the heating area be insulated
b) Startup and operation
1. Connect the 120VAC plug to the right most receptacle to power the controls (See Figure
3)
2. Determine where you will get power from.
Each plug utilized will draw the current shown in table 1. Carefully select power sources
as to not overload and trip breakers or fuses.
3. Connect all other desired 120VAC and 240VAC plugs.
The heater will function with only the right receptacle being powered. If all of the
receptacles are not being powered the unit will reach a lower maximum temperature and
the unit will take longer to heat a space to a desired temperature, if that temperature can
be reached. It is recommended that all receptacles are powered, especially for larger
spaces or a higher desired temperature
4. Ensure all cable sizes are sufficient to carry the expected current. Failure to size
conductors properly will lead to conductor overheating, which will damage conductors
and may pose a fire hazard.
5. ut the Main ower switch in the ON position. The fans should now engage, and the
digital thermostat should turn on.
6. To adjust the desired room temperature, put the Heat Applied switch in the ON position to
engage the resistors. ress the SET button on the thermostat, then use the U /DOWN
arrows to change the value displayed on the digital thermostat to the desired
temperature. For recommended temperatures to kill different bug types see Time in
Minutes to Mortality Chart.

7. The heater will now generate heat until the temperature at the thermostat reaches the
desired temperature. The heater will automatically turn the heater elements on and off as
required to control to the desired temperature being sensed at the thermocouple(s).
8. Allow the heater to hold the temperature of the room for the recommended time shown in
table Time in Minutes to Mortality Chart.
9. Note that your heater thermostat is programmed with a 2 °F hysteresis value.

c) Shutdown
1. ut the Heat Applied switch in the OFF position and lower thermostat value to below
standard room temperature.
2. Allow fans to operate at least three minutes or until exhaust air is cool before shutting
them off.
This cooling period will extend the life of your heater.
3. ut the Main ower switch in the OFF position.
4. Remove all 120VAC plugs and 240VAC plugs from the heater.
5. ut cables back into the storage box. (Not supplied by Mosebach)
6. Move the unit to storage.
6) Bug Killing Conditions
The conditions below represent the recommended run time once the entire area has
become fully heated. Enclosed spaces, such as clothes, beds, couches and drawers may
take significantly longer to reach desired temperatures than exposed surfaces in the
space being heated.
