Dear New COSTAR® Model 9SS Owner,

 

Congratulations as you have taken steps to help insure the health and life safety of you and your family.  We are proud 

to offer you our unique, patented CO Sensor technology that detects CO in a manner similar to the human body's response.  The 

COSTAR® 9SS 

is an ideal and low-cost way of warning you of both the acute and chronic effects of CO poisoning. 

Please read this owner's manual carefully so you will have a better understanding of the effects of CO poisoning and 

the 

COSTAR® 9SS 

Detector, as we work together pursuing a safer, healthier air quality for us all. 

To your good health and safety, 

 

Mark Goldstein, Ph.D.

Quantum Group Inc. 
 

The CO Safety Shutoff (COSS) is designed to give visual and audible signals and shut your appliance down if carbon monoxide 
(CO) reaches levels predetermined to be unhealthy or dangerous. 
 

IMPORTANT SAFETY INFORMATION 

WHAT SHOULD I DO IF YOU SMELL GAS? 

• 

Do not try to light any appliance. 

• 

Do not touch the electrical switch.

 

• 

Immediately call your gas supplier from a neighbor’s phone.  
Follow the supplier’s instructions.

 

• 

If you cannot reach your gas supplier, call the fire department.

 

 
Please study this entire manual before installation, and keep it handy for future reference. 
 
Please refer to your appliance owner’s manual for additional safety information. 
 
A CO Safety Shutoff is not a substitute for other gas, fire or smoke alarms.  This unit is designed to detect CO from any source 
of combustion; however, it will indicate the presence of CO at the sensor location only.  CO gas may be present in other areas of 
the building undetectable by your unit.  For better protection, install a CO detector as recommended by the Consumer Product 
Safety Commission (CPSC).
