each knob shaft provided.

2. Screw each knob into the bracket found on
both sides of the heater, but do not tighten.

3. With heater sitting on a firm surface, slide the
s

tand onto each knob shaft between the steel

and rubber washers (See Figure 2).

4. Tighten knobs.

Note: The heater must be operated with the stand
attached to the heater.

Wall Mount Assembly

1. Place steel washer, then rubber washer on
each knob shaft provided.

2. Screw each knob into the bracket found on

Specifications

Operation and Maintenance

WARNING: This heater is a major electrical
appliance and requires adequate electrical
connections for safe use. Plug the heater directly
into a 240 volt wall or floor receptacle.

Plug the electrical cord into a 240 volt receptacle.
The plug should fit tightly into the receptacle for
a proper electrical connection. Power to the unit
is indicated by illumination of the red light.

How To Operate Your Heater

NOTE: Before operating heater, Heater Inspection
and Assembly Steps 1 through 3 must be completed:

“AUTO” SETTING

1. Choose the “HI” or “LOW” wattage setting as

suggested in the Specifications table (See Above).

2. Set heater to “AUTO” position.

3. Turn the thermostat knob fully clockwise .

4. When the room reaches your comfort level,

turn the thermostat knob counter clockwise
until you hear a click sound. The heater

will automatically cycle around this preset
temperature.

5. To reduce the room temperature, turn the knob
counter clockwise . To increase the room
temperature, turn the knob clockwise .

NOTE:

The Hot One discharges air with a temperature rise
of 40˚F. In extremely cold circumstances, air emitted
from the heater will not feel hot. This is within
normal operational limits. As the room temperature
rises, the air emitted from the heater will also
increase.

IMPORTANT!

The fan operation will be delayed approximately
20 seconds on startup. This allows the element
to heat before blowing air, thereby eliminating
cold startups. Fan operation will continue for
approximately 90 seconds after elements shut off
to disperse residual heat.

Operation and Maintenance

Figure 3

“ON” SETTING

The fan can be operated continuously when set
to the “ON” position. For cooling or air circulation
(when no heat is desired), turn the thermostat to
the lowest setting possible by rotating the
thermostat knob counter clockwise .

N

OTE

If the thermostat is turned to a setting above room
temperature, the elements will turn on and heat
the area until the temperature reaches that set
point. Once the elements go off, the fan will continue
to run. This cycle will continue.

IMPORTANT:
DO NOT use breaker panel or fuse box or wall
thermostat to control outlet plug.

Maintenance

As needed or every six months, minimum

1. Allow the heater to cool, then disconnect the
power cord from power supply. To disconnect
heater, turn control to “OFF”, then remove plug
from outlet. IMPORTANT: The heater must be
unplugged before performing any maintenance.

2. Remove front diffuser grill by removing
the 4 screws (1 from each corner).

3. Wash grill with hot soapy water and dry
immediately, or use air compressor to
blow debris from grill louvers.

Parts List

4. While holding fan (to avoid damage or bending),
use an air compressor, hair dryer or vacuum on
blow cycle to blow debris through the outer
cabinet louvers and finned elements (Do not
touch elements. Elements have sharp surfaces).

5. Vacuum or blow air inside fan area without
t

ouching the elements.

6. Carefully wipe off the fan blade without
damaging or bending it.

7. Replace diffuser grill and secure with screws.

8. Re-connect power cord to power supply.

Resetting the Manual-Reset Limit Control

The heater is protected by a high temperature
manual reset switch, designed to open the heater
circuit when excessive operating temperature
i

s detected. If the manual reset limit control has
opened the heater circuit due to excessive
operating temperatures, the heater will not work or
may blow cold air until the limit reset button is
pressed. After allowing the unit to cool for at least
10 minutes and resolving the problem causing the
limit to trip (typically the heater is blocked or needs
cleaning); use a narrow object such as a ball-point
pen to access the reset button through the lower-
right hole marked “RESET”. Press FIRMLY and be
sure to listen and feel for a click indicating it has
been reset. If the manual reset continues to trip,
check heater clearances to make sure they meet
the recommended distances.
