PET OWNERS NOTE

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. The heater should not be placed immediately under a power outlet.

HEATER CONNECTION: Plug heater directly into 240 Volt AC, 60Hz, 25A wall outlet. Be sure plug fits 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 heater ON by turning the Power Knob (located on the top of the heater) away from the OFF position «0» to the FAN ONLY setting or to one of the two heat settings:

– LOW HEAT (3300W)
– HIGH HEAT (5000W)

For faster heat up or to increase the heat output, turn the THERMOSTAT CONTROL all the way to the MAX position. The thermostat function controls the temperature output. To decrease the heat output, turn the knob towards the MIN position. To completely shut off heater, turn the POWER KNOB to the OFF position « 0 » and unplug the heater.

NOTE: 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.

HEAT SETTING: This heater has a thermostat and two heat settings.
SETTING THERMOSTAT: At first turn the thermostat to MAX and let the heater operate with full power input. When the room temperature reaches the required value, turn the thermostat to left until it switches off. The thermostat will then switch on and off automatically to control the room temperature according to the preset value and keep the room temperature constant.

TURNING HEATER OFF

To shut the heater off, turn the THERMOSTAT to the OFF position «0» and turn the POWER KNOB switch to FAN ONLY position « » and let the heater cool down for two minutes. For heaters with the time delay stopping function – even if the power switch is off – the delay circuit may turn the heater on if the inner temperature has reached the preset temperature. The delay time depends on the ambient temperature. For 68°F ambient temperature, it is about 3-4 minutes. If the ambient temperature keeps being higher than 80°F, the delay function can not cool down the heater and the delay time may be very long or the delay circuit won’t open. Therefore, the user can only disconnect the heater from the power supply by pulling out the plug.
