top of the vessel. The end of the bracket with the three holes
should be facing up towards the top of the vessel.
3. Tighten the gray PVC ring onto the nipple. This will compress
down onto the top of bracket.
4. Attach the smaller bracket to the bottom of the vessel. The
bracket has a clip type fastener that attaches to the bottom rim of
the vessel. The end of the bracket with the three holes should be
facing down towards the bottom of the vessel.
5. Secure the top bracket to a wall by using three appropriate screws
or fasteners (not provided).
Be sure to leave plenty of clearance above vessel for servicing
the quartz tube and germicidal lamp. (For proper clearance, see
Specification Table on page 2)
6. Secure the bottom bracket to the wall by using three screws or
fasteners (not provided).
7. Use quality unions and ball valves on the inlet and outlet for
servicing the unit. See Page 2for a typical installation piping
layout. If sweat fittings are used, be sure soldering is done in such
a manner as not to allow heat to reach the UV vessel. If Schedule
80 PVC or CPVC is used, make sure to follow the proper primer
and solvent instructions.
8. Pipe the inlet into the bottom nipple of the UV vessel.
9. Install a 1’’ x 3/4” reducing bushing (not provided) into the inlet of
the solenoid valve.
10. Install the ¾” (for the ES7 and ES10 units) or the 1” (for the ES20
units) normally closed solenoid to the outlet on the top
nipple of the UV vessel. Make sure that the solenoid is installed in
the proper direction. See page 2 There is an internal flow
restrictor in the outlet nipple of all units. It is recommended you
install a boiler drain on the inlet piping of the unit. This will
allow for easy draining of the vessel when replacing the UV
quartz.
