MWC-E 304 Electro Polished SS Vessel Installation:
1. The ultraviolet unit is designed to be installed in a vertical position.
The unit is supplied with (2) brackets to support the unit.
NOTE: The upper bracket has a grounding lug attached to it.
2. Place the top bracket (larger one) over the nipple located at the 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
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 2 for 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 and the outlet into the top
nipple on the UV vessel. 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.
