Side Mounted Auto-Fill
The side mounted Auto-Fill option connects the on-site water
supply through the control panel to an Auto-Fill fitting on the
side of the well enclosure. Use the following procedure to install
a unit equipped with the side mounted Auto-Fill option.
NOTE: The Plumbing Kit that comes with this unit includes the
following parts: street elbow, back-flow preventer valve,
fill tube hose, and hose clamps. For a detailed image of
the Plumbing Kit, refer to "Drain Mounted Auto-Filll" in
this section.
CAUTION
Auto-Fill units must be installed with adequate backflow
protection and must conform with all federal, state, and
local codes.
NOTICE
Auto-fill units supplied with water from a reverse osmosis
(RO) system (or similiar water filtration system) must be
installed with an operating reminerialization sytem to
ensure proper operation. Failure to do so may cause unit
to overfill. Damage caused by overfilling is not covered
under warranty.
Drain sealants must have temperature rating of 500°F (260°C)
or higher. Incoming water pipes must be FDA compliant for
potable water.
1. Connect the street elbow to the Auto-Fill fitting located on
the outside of the well. Replace the fill tube hose on fitting.
NOTE: The fill tube hose may need to be removed from the
Plumbing Kit for ease of installation.
2. Connect the fill tube hose to the fill valve nipple in the
control enclosure and secure using the hose clamp.
(Disassemble the control enclosure trim cover to access
the nipple.)
3. Connect the on-site water supply line to the 1/4" NPT water
inlet fitting on the control enclosure.
