WARNING
Water Contamination Hazard.
The overflow drain line must not be connected
to any drain. It must be routed to an open drain
leaving a air gap separating the overflow drain line
from the top of the open drain reservoir.
8. Using the section of the flexible hose marked and/or coming from
outlet (E) side of the water tank, route this line to an OPEN FLOOR
DRAIN. This drain MUST not be directly plumbed to the auto fill unit. This
is done to prevent contamination of the fresh water supply. See Figure 4.
9. Using the section of the flexible hose (A) coming from the “IN” or “I” side
of the solenoid (B) connect this hose to your fresh water source. See
Figure 4.

1. Plug the auto-fill control box into a grounded 120 Volt 15 Amp electrical
outlet.
2. Verify the main drain valve is in the CLOSED position to prevent water
from draining out. Be sure the individual well drains are in the OPEN
position to allow water to fill the wells from the drain manifold.
3. Turn the fresh water supply valve on. Start with the valve in the full open
position.
4. Turn on the Auto-fill system using the switch on the control assembly.
The red indicator light should come on indicating power is supplied to the
unit and water should flow into the system.
NOTE: If a continuous stream of water begins to flow out of the
overflow tube when filling the unit, stop filling and drain the unit. Close
the water supply valve from step 3 part way to reduce water flow. Refill
unit. Continue this process until water does not flow out of the overflow
when filling the unit. It is normal to have small amounts of water flow
out the overflow while the unit is filling.
5. The auto-fill system may cycle on and off a few times, with delays,
before the water level is stabilized. The number of cycles and delays are
dependant on water pressure, number of wells filling, etc. Do not attempt
to adjust the water level until the system has fully stabilized. When the
system does not cycle on or off after a full minute, the system should be
stabilized.
6. When the system is stabilized, check the water level in each of the wells.
For proper water level control it is important the hot food unit be level.
Each well should have approximately the same amount of water.
7. If the water level is too low, loosen (do not remove) the screws used
to mount the reservoir assembly. Lift the reservoir assembly up
approximately 1/8”. Retighten the screws. There may again be a delay
before the system begins to fill. Allow the system to stabilize again and
re-check the water level.
8. Continue the adjustment until you have the water level adjusted to the
desired level. The water level should not be adjusted above 1/2” of water.
9. For most efficient heating and performance, use approximately 1/4” of
water in each well.
