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.
Recognize safety information. This is the safety-alert symbol        . 

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 

used to highlight suggestions which will result in enhanced installation, 

reliability, or operation.

GENERAL

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

2

 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

TM

 controller).  See Table 

3 for sensor usage.

WARNING

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.
