NOTE: The temperature/pressure table at right
is for reference only. A unit's temperature/pres-
sure correlation may differ from those listed due
to: variations in evaporator thermistor location,
set-points, where the sealed system is in the
refrigeration cycle, etc.
If a unit is experiencing temperature problems,
it is recommended to reference the General
Troubleshooting guide and follow any "Pointers"
that may appear in the first column. After all
mechanical and electrical components have
been ruled out, sealed system pressures can
be checked by applying solder-on process
valves and referencing the preceding page. Do
NOT use bolt-on process valves as they are
prone to leak.
This table should only be used as a last quick
check before entering the sealed system.
