Mounting The UV Unit On A Solid Base - The next step is to secure the DELTA UV unit to a concrete or
wood base. Three mounting holes are located in the mounting base of the DELTA UV unit. These holes
accommodate ¼ inch diameter bolts to mount the DELTA UV unit in place. FAILURE TO PROPERLY
SECURE THE UNIT MAY CAUSE NOISE DUE TO VIBRATION CAUSED BY WATER PASSING
THROUGH THE WET CHAMBER. Secure the DELTA UV unit using bolts and anchors (not supplied) where
necessary and appropriate for your installation. When the DELTA UV unit is secured in position, the piping of
the unit can begin.
Gluing Piping To The UV Unit - The Inlet/Outlet PVC union tail pieces are 2 inch pipe size (63mm for overseas
models). Your PVC supply piping should be glued into the union tail pieces using an appropriate PVC primer
and PVC cement, as recommended by your supplier. Inlet piping should be supported and should not rest solely
upon the unions, to avoid breaking the unions. The installation of valves on the inlet and outlet lines
attached to the UV unit is recommended. If the DELTA UV unit is located with any portion of the unit
below the surface of the pond or pool, then VALVES ARE MANDATORY, so you may winterize or remove
the DELTA UV unit without draining your pool or pond. When you have completed the piping installation
(including bypass if necessary), the final step is to plug in the unit to its power source. It is very important
to mount the ballast a minimum of 16 in. above the ground.
