Verify that the power switch is turned
clockwise to the operating mode position
and not counter-clockwise to the standby
mode position.
• Note on safety reset switches:
The pour-over module features two safety
reset thermostat controlled switches, one
on each boiler. If a boiler does not heat
it may be due to the activation of one
of these switches, which is triggered by
excess temperature and signies abnormal
operation and possibly failed components.
The safety switches mentioned are all
internal to the pour-over module and are
not user re-settable. If you believe a safety
switch has been activated, the module or
tap may require service by an authorized
technician. Please contact Modbar for
additional support and information.
