SAVE THESE INSTRUCTIONS
USAGE:
HEATER OPERATION:
Always operate the heater in the upright
position following all instructions and recommendations listed in this
manual.
HEATER LOCATION:
Place the heater in the area of the room that is
coldest.
HEATER CONNECTION:
Plug heater directly into 120 volt A.C.,
60Hz wall outlet. Be sure plug ts tightly in outlet. A loose connection
may cause overheating and damage to the plug or heater.
NOTE:
To
prevent overloading a circuit, do not plug the heater into a circuit that is
servicing other electrical needs.
TURNING HEATER ON:
To start the heater, turn the ON/OFF
Power Level/Fan Dial from the OFF position to the 1300 or 1500 watt
setting. Then rotate the Thermostat Control clockwise to the HIGH
THERMOSTAT position as described below. (During the heaters initial
use, you may experience a slight odor or smoking. This is the result of
the heating element lubrication “burning off”. This is normal and will go
away after a few minutes of use.)
POWER LEVEL SWITCH:
This heater has two heat settings: 1300
and 1500 watts. Use the higher setting (1500 watt) to raise the room
temperature quickly. When the desired temperature is reached use the
lower 1300 watt setting. It is usually sufcient to maintain a comfortable
temperature.
ADJUSTABLE THERMOSTAT WITH ANTI-FREEZE SETTING:
After heater has been turned on and the room has reached the desired
temperature, slowly rotate the thermostat knob counter-clockwise until
the heater shuts off (you should hear a faint “click”). By leaving the
thermostat at this setting it will automatically maintain this temperature.
To lower temperature, rotate the knob further counter-clockwise
(towards the LOW position). To raise the temperature, rotate the
thermostat knob clockwise (towards the HIGH position).
When set to the Anti-Freeze setting, the Heater will turn on whenever
the temperature drops below 40°F, which is helpful to economically
prevent ice formation in garages and other unheated spaces.
TURNING HEATER OFF:
Turn the ON/OFF Power Level/Fan Dial
to the OFF position before unplugging or plugging in the heater. Heater
should be unplugged when not in use. To disconnect heater, turn
controls to OFF, then remove plug from outlet.
ASSEMBLY INSTRUCTIONS:
Before initial use some assembly is required. With a phillips screwdriver,
attach handle to heater body using screws provided as shown in the
photo.
