Installing an Auto-Fill Unit

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.
Auto-Fill units must be installed with adequate backflow
protection and must conform with 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 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 fill
tube assembly 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.
4. Turn on the water supply and check for leaks.

Installing a Bottom Mount Unit

Installation of a bottom mount unit requires custom fabrication of
the countertop by a qualified and experienced installer. Use the
following information as guidelines for one method of installing a
bottom mount unit. Refer to the OPTIONS AND ACCESSORIES
section for installation with an optional mounting bracket.
• Create the countertop cutout with turned-down flanges on
all four sides. These flanges should be positioned on the
inside of the well for installation.
