5.3 Installing Inlet/Outlet Unions - The EP unit comes with union nuts installed on the housing. Packed

with your EP unit are the remaining components necessary to complete the Inlet/Outlet unions. The clear

union tail piece is used on the top union, and the solid color union tail piece is used on the bottom union. Also

packed with your EP unit are two white gaskets that are used to complete the Inlet/Outlet unions. One side

of the gasket is flat, the other side has a half round bead on the face. The two unions each have a groove in the

face of the union tail piece and that groove accepts the half round bead of the gasket to hold the gasket in

place correctly. Place the gaskets into the face of the union tail pieces. Now, install the union tail pieces by

screwing them into the union nuts on the EP unit. DO NOT OVERTIGHTEN. Hand tightening is sufficient.

OVERTIGHTENING WILL BREAK THE UNION NUTS.

5.4 Installing Pressure Gauge - Your EP unit also comes with a pressure gauge that is used to confirm that

your pump is not exceeding the 40 PSI maximum working pressure for the EP UV unit. The pressure gauge

is shipped with Teflon sealing tape on the gauge threads. To install the pressure gauge, you screw it into the

threaded tap on the clear union tail piece that you have installed on the EP unit. If the EP unit is installed

indoors, the pressure gauge can be installed so it is facing upward. However, if the EP unit is installed

outdoors, the pressure gauge must be installed on one side or the other of the clear tailpiece so that it will be

in a vertical position when installed. Installing the gauge facing upwardly when the EP unit is outdoors will

result in the gauge filling full of rainwater and will ruin the gauge. The gauge location and orientation that you

choose is dependent upon which side of the fitting provides the best viewing of the gauge dial.

Be sure to use a wrench to tighten the pressure gauge into the clear tail piece, using the square brass boss

on the back of the pressure gauge. DO NOT OVERTIGHTEN. Over tightening will cause the clear plastic

union tail piece to crack. Three or four threads are all that is necessary to seal the pressure gauge. If the

gauge leaks upon start-up, simply tighten one more rotation. DO NOT TIGHTEN BY GRASPING THE COVER

OF THE PRESSURE GAUGE. Only use the square brass boss on the back of the pressure gauge for

tightening with a wrench.

5.5 Mounting The UV Unit On A Solid Base - The next step is to secure the EP unit to a concrete or wood

base. Four mounting holes are located in the mounting base of the EP unit. These holes accommodate ¼

inch diameter bolts to mount the EP 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 EP unit using bolts and anchors where necessary and appropriate for your installation. (not

supplied) When the EP unit is secured in position, the piping of the unit can begin.
