Water Tank Not Filling at Start Up
Issue:
At initial install the water tanks will not fill.
Solution:
When the unit is powered on the touchscreen should show the following:
1.
Warming Up and software versions displayed
2.
No CO2 (because the CO2 should not be turned on at startup)
3.
Home Screen with two red icons on the bottom right of the
touchscreen (low water and low CO2pressure)
The Lavit Button should be flashing RED. Press the Lavit button firmly and the inlet
and cold tank solenoids will open and the tanks will fill. You should hear the
solenoids engage and the water running. If the above does not resolve the issue
then the inlet solenoid or the cold tank solenoid is not opening.
This can be caused by the f o l l o w i n g:
1. The inlet water pressure may be above 60 psi. High water pressure will
mechanically prevent the inlet solenoid from opening. Check the water
pressure and ensure a pressure reducer on the inlet line (40to 60 psi)
has been installed.
2. There is no power to the inlet solenoid or the cold tank solenoid. Remove the
top of the unit keeping the connectors attached. Access the main PCB by
pulling back the black plastic cover over the PCB on the front right side of
the unit. Find the 4th connector from the left on the top row of connectors (a
dual red connector with two white and a red and black wires). Also locate the
cold tank solenoid connection
(small white connector at the top of the right- hand side of the PCB). Follow
the above start up instructions. Look for red lights to illuminate next to the
red and small white connectors when the Lavit button is depressed firmly. If
no lights are illuminated or just one light then check that the connectors are
properly seated. Also follow the white leads from the red connector back
from the connector to a secondary connector. Ensure the secondary
connector is properly seated. Recheck by restarting as above.
3. If the lights still do not illuminate, the electrical float mechanism in the cold-
water tank may be faulty. To verify - on the right side of the PCB remove the
red connector and the white connector with the blue w i r e
