●
The instruments has low power sign. When it is displayed , it
means the battery power is insufficient. At this time, the battery
should be replaced as required in order to avoid affecting
normal use.
●
Please check the pipe fittings and the hoses before testing.
Once any damage is found , please replace it immediately to
avoid improper use or any accident occurring.
●
There is a valve core in the refrigerant inlet of the refrigeration
system. When connecting the instrument, pay attention to the
two terminals of the hoses. Connect one terminal with a core to
the refrigeration system, while another terminal without a core
to the instrument.
●
Every hose terminal comes with a nylon pad that is limited a
certain life of using. Over use or other situation will make it
defective, which result in leakage.
●
The instrument refrigerant inlet (the middle port of the instru-
ment) has a port with valve core, which is used to vent the air
in the hoes after connecting the refrigerant to the instrument.
●
The port is equipped with a copper plug screw. It is required to
tighten it every time before or after operation.
●
Check the refrigeration system's pipes and connectors.
