SAFETY CONSIDERATIONS
Installation and servicing of air-conditioning equipment can be
hazardous due to system pressure and electrical components. Only
trained and qualified service personnel should install, repair, or service
air-conditioning equipment.
Untrained personnel can perform the basic maintenance functions of
replacing filters. All other operations should be performed by trained
service personnel. When working on air-conditioning equipment, observe
precautions in the literature, tags, and labels attached to the unit, and
other safety precautions that may apply. Follow all safety codes. Wear
safety glasses and work gloves.

When you see this symbol on the unit and in instructions or manuals, be
alert to the potential for personal injury.
Understand the signal words DANGER, WARNING, and CAUTION.
These words are used with the safety-alert symbol. DANGER identifies
the most serious hazards which will result in severe personal injury or
death. WARNING signifies a hazard which could result in personal
injury or death. CAUTION is used to identify unsafe practices which may
result in minor personal injury or product and property damage. NOTE is

ELECTRICAL SHOCK HAZARD
Failure to follow this warning could cause personal injury and/or
death.
Disconnect power supply and install lockout tag before attempting to
install the accessory.
The EconoMi$er2 system utilizes the latest technology available for
integrating the use of free cooling with mechanical cooling for rooftop
units.
This system utilizes gear-drive technology with a direct mount spring
return actuator that will close upon loss of power. The EconoMi$er2
system comes standard with an outdoor air temperature sensor. Field-
installed CO sensors are available.

Standard barometric relief dampers provide natural building pressurization
control. An optional power exhaust system is available for applications
requiring even greater exhaust capabilities.
EconoMi$er2 accessories have a 4 to 20 mA actuator signal control.
These accessories do not include the EconoMi$er2 controller. The
EconoMi$er2 actuator is operated by a 4 to 20 mA signal from an existing
field-supplied controller (such as PremierLink
