When no longer needed, dispose of all packaging and materials in an
environmentally responsible manner. Have the unit installed only by qualified
service personnel. This unit must be installed in accordance with any local
and national plumbing codes.
„ A shut-off valve to control the fresh water supply to this product is
required.
„ This unit requires a 120Volt 15Amp electrical outlet.
„ Units using this auto-fill unit MUST NOT SHARE A DRAIN LINE with
any other units that do not have the same well depth.
„ Multiple units with the same well depth may share a drain line provided
they are level to each other within ¼”.
„ Maximum water pressure is 80 PSI.
NOTE : A water filter to remove particles that may clog the solenoid valve is
strongly recommended.
1. Remove all packing material and tape, as well as any protective plastic
from the equipment.
2. Clean any glue residue left over from the plastic or tape.
3. If installing this Auto-fill on a Vollrath drain manifold, cut off the pipe cap
from the end of the drain manifold assembly that is on the opposite end
of the main drain valve.
4. Solder the Auto-Fill manifold assembly (A) to the open end of the drain
line (B) from step 2 making sure the auto fill manifold is level with the
existing drain manifold. Figure 1.

5. For installation with Rectangular Drop-In For initial setup, mount the
Auto-Fill main body water reservoir (B) level to the bottom of any full size
Vollrath hot well (C) unit outer skin. Mark and use appropriate length
fasteners to mount reservoir (B) assembly in a level position (D) to the
bottom of the well assembly (A). See Figure 2.
6. For use with Round Soup Drop-In: Install the reservoir (B) 5/8”
(15 mm) below the bottom of a Vollrath round soup drop in unit outer
skin. See Figure 2.
1. The adjustment procedure above should be used with soup pots with
the understanding that the water level the unit will maintain is the water
level when there is a soup pot in use. The recommended 5/8” (15 mm)”
placement of the reservoir below the soup warmer (In the installation
section above) will maintain water at the water level mark in the well.
However at this level, if a soup insert is placed into the soup warmer that
has water filled to this mark without an insert in place, when inserted the
insert will displace some of the water up the sides of the soup warmer.
Because the water will level out in the entire system, this may cause the
reservoir tank of the auto-fill unit to overflow.

tatement
This Auto-fill unit operates by filling a water reservoir that represents an
additional well. This reservoir has a float switch installed that is closed when
the tank is empty. When the Auto-Fill system is turned on, the closed float
switch allows power to flow to the solenoid valve, opening the solenoid valve
and allowing water to flow into the drain system through a check valve.
As water fills the drain line, it will fill each well and the Auto-Fill reservoir at
approximately the same rate. When the water reaches the float switch, the
switch will open, stopping the power supply to the solenoid valve and the
solenoid valve will return to its normally closed position stopping the flow of
water into the system.
