SAFETY INSTRUCTIONS

WARNING - to guard against injury, basic safety precautions should be observed,  

including the following:

1.  READ AND FOLLOW ALL SAFETY INSTRUCTIONS.

2.  DANGER

 - To avoid possible electric shock, special care should be taken since water is present 

near electrical equipment.  Unless a situation is encountered that is explicitly addressed by the 

provided maintenance and troubleshooting sections, do not attempt repairs yourself, refer to an 

authorized service facility.

3.  Carefully examine the disinfection system after installation.  It should not be plugged in if there 

is water on parts not intended to be wet.

4.  Do not operate the disinfection system if it has a damaged power cord or plug, if it is malfunc-

tioning or if it is dropped or damaged in any manner.

5.  Always disconnect water flow and unplug the disinfection system before performing cleaning 

or maintenance activities.  Never yank the power cord to remove it from an outlet.  Grasp the 

plug and pull to disconnect.

6.  Do not use this disinfection system for other than the intended use (potable water applications.)  

The use of attachments not approved, recommended or sold by the manufacturer / distributor 

may cause an unsafe condition.

7.  Intended for indoor use.  Do not install this disinfection system where it will be exposed to the 

weather.  Do not store this disinfection system where it will be exposed to temperatures below 

freezing unless all the water has been drained from it and the water supply has been discon-

nected.

8.  Read and observe all the important notices and warnings on the water disinfection system.

9.  If an extension cord is necessary, a cord with a proper rating should be used.  A cord rated for 

less Amperes or Watts than the disinfection system rating may over heat.  Care should be taken 

to arrange the cord so that it will not be tripped over or accidentally pulled from the outlet.

1.  SAVE THESE INSTRUCTIONS.

WARNING:  

The light given off by this unit can cause serious burns to unprotected eyes and skin.  

Never look directly at a lit UV lamp.  When performing any work on the UV Disinfection System, 

always unplug the unit first.  Never operate the UV system while the lamp is outside of the UV 

chamber.

WARNING:  

The UV lamp inside of the disinfection system is rated at an effective life of approx-

imately 9,000 hours.  To ensure continuous water treatment, replace the UV lamp  

annually with the appropriate Aqua Treatment Services UV lamp.  Failure to comply may  

present a fire hazard.
