Where do I install my new CaluTech UV Purifier?

 
 

The best air purifier installation location is over the top of the "A" evaporator coil.

If you have A/C we recommend installation above the Evaporator Coil. If you do not know where the coil is, look for a drain hose or copper lines entering your air duct. This is where the coil is. You want to install the unit above this coil. Because coils are always wet, even when the A/C is not running, it becomes a breeding ground for bacteria, viruses, dust mites, and mold. The UV light shining down on this coil burns all of these pathogens up. DO NOT drill right into the duct where the drain or copper lines are coming out. You must install it above the coil. If you run a drill bit into this coil all the freon will come out and you will need an HVAC contractor to open the duct and repair the coil, or even replace it. A good idea is to open the panel to look where it sits so you know you've installed it in the right spot (see illustration at right). If you do not have A/C you can install the unit easily in the cold air return line, which is the duct that brings the air in the home or building to the furnace so it can be heated (see illustration below).

If you're in doubt, call a heating & air conditioning company to install it for you. It doesn't cost much to have it professionally installed. Install time is usually around 30 minutes.

Either illustration above shows the two places you can install: Above the Evaporator Coil or in the Cold Air Return Line at the bottom of the unit.       

 

Warning and Safety Notice

Never expose eyes or skin to the UV light. Looking directly at the UV bulb when it is on can cause flash burn to the eyes (welders flash). Never operate outside of the ventilation system. Only install in a closed duct system, not at any vent openings.

 
Tools Needed
(1) Drill and a 2 inch hole saw
(2) Phillips head screwdriver

 

Attaching Bulbs

Be sure to follow the instructions with your UV system and be very sure to attach bulbs in the proper order as instructed. The unit is labeled and tells you which bulb to attach first. This is to avoid hitting UV lamps together, causing broken bulbs.

Be sure to use the plastic gloves provided with your UV system. This is to keep the oil from your hands getting on the bulbs, which can shorten the life of the bulbs.

 

Step 1

After unpacking your UV system, start by removing the two small red thumb screws that secure the 2-piece system together. You also use these thumb screws to open the system and change UV lamps when needed. These small red screws are on each end.

 

Step 2

Once removed you can lift the cover off of the power supply. You will use the cover as a mounting template. This system can be installed vertically or horizontally. In these images it is being installed horizontally.

 

  

Step 3

Hold the cover where you will install the UV system and use a marker pen to trace the 2 large holes and the 4 small holes on the cover as shown below. A drill bit for the 4 small holes is provided with your UV system. You will need to purchase a 2 inch Bi-metal hole saw for your drill. You can get this accessory at a local hardware store. Installation is easy, but I locally install this system for $30. It normally takes less than 30 minutes, with coffee! Mark off your 2 inch holes and screw holes for drilling as indicated below.

Step 4

After marking your drill holes, using a drill with a 2 inch hole saw, simply center the saw over the 2 large holes and drill them out for the UV lamps. You can also use a larger hole saw up to 2 1/2 inches.

  

Step 5

With the supplied drill bit you will now drill out the 4 small holes in each corner. These holes are for mounting screws that secure the unit. The screws are supplied with your UV system.

  

Step 6

Now that the holes are drilled out, simply screw the cover to the air duct with the supplied screws.

 

Step 7

Now attach the UV lamps. Be sure to refer to the instructions that came with your UV system to learn how they snap into place. Handle only the base of the bulb and be sure to wear the plastic gloves provided to protect your bulbs from oil from your hands.

  

Step 8

After attaching lamps, be very gentle and attach the UV system by inserting lamps into the holes, guiding them in slowly.

  

Step 9

Now fit the 2 pieces back together and screw the 2 red thumb screws back into place to secure the system. Connect power and turn on.
