Complete installation instructions and diagrams are included with each unit. The instructions below are intended to show the ease with which a system installs and for users who do not have access to their included instructions. 

We strongly recommend the use of an extension cord for those users who will be using an electrical outlet behind their dishwasher. This will prevent you from having to pull out your washer any time you need unplug your SAFH2O UV system to perform maintenance. For added safety, it is always best to plug into a GFI outlet.


Installation Instructions For SAFH2O UV Under Counter Water Systems
The instructions below are the same whether for dual, triple or quadruple stage units. The Model 100 should not require faucet installation, as the system is intended only for use in conjunction with an existing filtration system.

To install saddle valve on copper tube:
Caution: Do not turn handle before or while installing the “saddle tapping valve”. Be certain the piercing lance does not protrude beyond the rubber gasket. Failure to do this may result in damage to the lance.
•Assemble the “saddle tapping valve” on copper tube.
    • For 3/8 O.D. tubing use Pat. Pend. Bracket with side projections to prevent distortion of
    • Use “V” side of bracket for all larger size tubing.
•Tighten screws evenly – brackets should be parallel. Tighten firmly.
•Make the water connection to the outlet of the “saddle tapping valve”. Should you fail to do this before piercing the tube a small amount of water will escape from outlet until you are fully pierced.
•Turn the handle clockwise until you feel it is firmly seated.  Note: You have now pierced the copper tube and the valve is closed.
•Turn the handle counter clockwise to open the valve.

To install the “saddle tapping valve” on steel or brass pipe.
• Shut off water supply and drain the line.
• Drill a 3/16” hole in pipe. Use a hand drill to avoid shock hazard.
• Turn handle to expose lance beyond the rubber gasket no more than 3/16”
• Place body of valve over hole so that lance fits into the hole.
• Tighten bottom clamp evenly – brackets should be parallel.
• Turn handle clockwise to close the valve.
• Open the water supply and “saddle tapping valve”

Install Faucet
Many sinks have an extra hole for the mounting of additional faucets, sprayers or soap dispensers. If your sink does not have the additional hole, you will need to drill a hole as follows: First, determine the location for the faucet hole. Before you begin drilling, check underneath sink making certain there are no obstructions.
Stainless Steel Sink. Carefully mark the faucet location, making certain that it is far enough from the regular water faucets so that they don’t interfere with the operation of each other. Be certain there is sufficient clearance to tighten the lock nut from below before you begin the drilling procedure. Use center punch to make an indentation in sink surface to help hold alignment to drill the hole. Drill a 1/2” hole (max), and then smooth out rough edges with a file if required.
Porcelain Coated Sink. The manufacturer recommends to have this type of sink professionally drilled because of the possibility of chipping or cracking. If you are attempting to drill, use extreme caution. Use a Relton Cutter with adequate cooling lubricant. You may also install the faucet directly into the countertop if you do not want to drill the sink. Position the faucet at the location to be drilled to make certain that the end of the spout will reach over the sink. Feel underneath the countertop to make certain there is no obstruction that would prevent proper faucet installation.
