Filtrete 3M-22 Manuel De Montage

To avoid electrical shock and to prevent damage to the furnace, air conditioner, 
and thermostat, disconnect the power supply before beginning work. 
This can be done at the circuit breaker, or at the appliance.

Replacement installations - mount the new thermostat in place of the old one.

 
New installations -  follow the guidelines listed below. 
• Locate the thermostat on an inside wall, about 5 ft. (1.5m) above the floor, and 
in a room that is used often.

• Do not install it where there are unusual heating conditions, such as: in direct 
sunlight; near a lamp, radio, television, radiator register, or fireplace; near hot 
water pipes in a wall; near a stove on the other side of a wall.
• Do not locate in unusual cooling conditions, such as: on a wall separating an 
unheated room; or in a draft from a stairwell, door, or window.
• Do not locate in a damp area. This can 
lead to corrosion that will shorten thermostat 
life. 
• Do not locate where air circulation is poor, 
such as: in a corner or an alcove; or behind 
an open door. 
• Do not install the unit until all construction 
work and painting has been completed.
• This thermostat does not require leveling.

You will need a small Phillips screwdriver and possibly a drill 
with 3/16-in. (4.8mm) bit for wall mounting.
