SERVICE
Other Suspected Main Control Faults
If other components have been ruled out as being faulty
but the unit continues to have operating issues, it is most
likely due to a configuration error. Configuration errors
can be cleared by restoring the unit to its factory default
setting. Factory defaults may be restored through the
service menu.
CAUTION
!
Precautions must be taken while working with
live electrical equipment. Be sure to follow
proper safety procedures while performing tests
on live systems.
AIR FLOW
NOTICE
The unit requires proper air flow to perform at
its highest efficiency. Do not block the front
grille, internal fans or vents at any time, or the
unit will not perform as expected. Do not install
the unit behind a door.
Quick Chill
CAUTION
!
Quick chill is designed to quickly pull warm
beverages and foods down to optimum storage
temperature. It is important to only initiate
quick chill modes when the unit has been fully
loaded with warm product.
To Initiate quick chill
1. Press to select the desired mode setting.
2. Press
until the temperature set point reads “Quick”.
The quick chill feature will then begin for the period of
time dictated by the mode type. To cancel quick chill
simply select a set point other then “quick”.
Relay Toggle
Relay toggle is used to manually switch the state of each
relay to test for proper operation. In addition to the AC
relays, DC outputs may also be toggled. Relay toggle can
also be used to force the unit into a particular state. For
example, to force a 3018 / 3045 into a cooling cycle
activate Comp, F1, and F3.
