IMPORTANT
INSTRUCTIONS
When using electrical appliances, basic precautions should always
be followed to reduce the risk of fire, electric shock and injury to
persons, including the following:
1.
Read all instructions before using the heater.
2. This heater is hot when in use. To avoid burns, do not let bare skin
touch hot surfaces. Always use handle when moving heater. Keep
combustibles such as furniture, pillows, bedding, papers, clothes,
and curtains at least 3 feet (.9 m) from front of heater and keep them
away from 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. Always unplug heater when not in use.
5.
Do not operate any heater with a damaged cord or plug, if heater
malfunctions, or has been dropped or damaged in any matter.
Heater must be repaired by qualified electrician.
6. Do not use heater outdoors.
7. This heater is not intended for use in wet or damp locations. Never
locate heater where it may fall into bathtub or other water container.
8.
Do not run cord under carpeting. Do not cover cord with throw rugs,
runner or the like. Arrange cord away from traffic area and where it
will not be tripped over.
9. To disconnect heater, turn selector knob to the “OFF” position, then
remove plug from outlet.
10. Connect to properly grounded outlets only.
11. Do not insert or allow foreign objects to enter any ventilation or
exhaust openings as this may cause electric shock or fire, or dam-
age the heater.
12. 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.
13. A heater has hot and arcing or sparking parts inside. Do not use it
in area where gasoline, paint, or other flammable liquids are used or
stored.
14. Use heater only as described in this manual. Any other use not rec-
ommended by the manufacturer may cause fire, electric shock, or
personal injury.
15. Avoid the use of an extension cord because the extension cord may
overheat and cause a risk of fire. However, if you have to use an
extension cord, the cord must be at least No. 14 AWG and rated not
less than 1875 watts. (MMHD requires 3 wire grounded cord and
plug.)
16. This heater is provided with an alarm (buzzer) to warn that parts of
the heater are getting excessively hot. If the alarm sounds, imme-
diately turn the heater off and inspect for any objects on or adja-
cent to the heater that may cause high temperature. DO NOT
OPERATE THE HEATER WITH THE ALARM SOUNDING.

Assembly
This heater comes with the handle unattached. Use the screws provided to
attach handle to the top of the heater.
Model MMH 1502TA
The MMH heater is equipped with a polarized (2-blade) plug with one-blade
wider than the other.
CAUTION: The polarized plug will fit into the wall outlet in only one way. If it
still does not fit, contact an electrician to replace your obsolete outlet.
DO NOT defeat this important safety feature. To do so could result in an
electric shock hazard.
Model MMHD 1502TA
The MMHD heater is provided with a grounded (3 blade) plug.
CAUTION: The grounded plug must be used with a grounded outlet. Do not
use an adapter in a 2-slot wall outlet unless the ground lug of the adapter is
properly connected to a known building ground. Failure to use heater with
properly grounded outlet or adapter could result in an electric shock hazard.
TO OPERATE
1. Plug the heater power cord directly into a standard grounded 110-120 volt
AC outlet. Always operate the heater in the upright position with the rubber
feet on the floor.
CAUTION: Be sure plug fits tightly into outlet. A loose fit will cause overheat-
ing and damage to the plug. Plug may feel warm during normal usage. If you
must use an extension cord with this heater, the extension cord must be at
least a No. 14 AWG rate for for 1875 watts. (MMHD requires 3 wire ground-
ed cord and plug.)
2. Rotate wattage selector knob to the “1500 W” position This provides the
maximum heat output.
3. Rotate the “THERMOSTAT” knob clockwise (right) to the “HIGH” setting
until the knob stops. The heater should begin heating and the fan should
start to blow warm air.
4. Allow the heater to operate until the room temperature reaches the desired
level, then slowly rotate the “THERMOSTAT” knob counter-clockwise (left)
until the heater cycles off. At this setting, the heater will cycle on and off
automatically to maintain this comfort level.
NOTE: Do not force knob beyond its normal stop position. It may be neces-
sary to make minor adjustments to the thermostat to maintain the desired
comfort level. Clockwise movement will increase the room temperature.
Counter-clockwise movement will decrease room temperature.
5. To conserve energy, the heater may be operated at a lower wattage by
rotating control knob to the “1300 W” position.
6. When heater is not needed, rotate control knob to the “OFF” position,
remove the plug from outlet, and move heater to safe place for storage.
IMPORTANT NOTE
Do not expect the heating coils on your heater to glow. Coil elements are nor-
mally dark. Air movement over these coils prevents glowing yet provides
warm air, similar to a forced-air furnace. Some glow may occur where the
moving air does not directly touch the coils.
