1 Schematic diagram of System Flow Chart
2 Brief Description of System Fl ow Chart
Model UL-ZB28C2 is a direct cooling single-system appliance.
When the appliance is just powered on, the refrigerant flows in the
sequence: 1->2->3->4->5>1

Brief Description of Control Principle
Model UL-ZB28C2 is a direct cooling single-system Ice-marker . A
mechanical type of all the control is generally adopted. The thermostat
directly controls the start and stop of compressor, and hence the
appliance temperature.

Maintenance Service and Trouble Shooting
1. No cooling
can run after it stop to
run five minutes and
give power.
Check and repair according to
the section of "the compessor
doesn't work".
If compressor
can run naturally and
temperature raising
of condenser is
very l ow
leak,check and
repair charge
things,change filter and change
refrigerant again.
When charging refrigerant,we must
notice to make refrigerant true.

2 The compressor doesn't stop
Check and repair according to
the section of "No cooling" .
Check and repair according to
the section of "Cooling ca pacity
set at the coldest position.
2 The ambient temperature is very high or
the appliance is near by heat r esour ce.
3 The door was opened too many
times or there are more
Check and repair the main
control panel
