Maintenance - Mr. Heater MH530FAERT Operating Instructions And Owner's Manual

Operational Information
Heat is created by electric current passing through coiled metal
elements bringing them up to very high temperatures. The
fan then passes room air over the hot elements exchanging
cold air for warm. The air moving over the coils keeps them
from reaching temperatures that are not safe for the normal
operation of the heater. Therefor it is important to keep all
combustible materials and any objects that may be sucked
into the fan blades at a safe distance (please refer to the
specification table for appropriate clearances). Make sure that
the fan blades remain unobstructed at all times. Keep unit clean
and dust free. Do not block unit intake or exhaust at any time.
If damage has occurred please refer to the parts listing in this
manual and contact the manufacturer for a replacement.
WARNING: The electrical circuit must be properly grounded,
failure to do so may result in electric shock or property
damage.
WARNING: Always plug or wire heaters directly into a wall
receptacle or appropriate junction box. Never use with an
extension cord or re-locatable power tap (outlet/power strip).
These Electric forced air heaters are specifically designed to
be permanently installed by hanging from ceiling or overhead
structure. Do not attempt to use them as a portable heater.
Starting Instructions
1. With the heater properly installed and the power supplied to the unit
move the heat selection knob to the setting you want. There are both
high and low settings, along with a fan only option. Refer to Figure 3,
for information about each setting.
2. Turn thermostat to desired setting. Clockwise will increase the set
point, counter clockwise will reduce the setting. An audible click can
be heard when the current temperature in the space is matched on the
dial.
3. The Heating element and fan will remain on until the temperature
setting is reached. The unit will cycle on and off as needed.
