NOTE:
The temperature/pressure table at
right is for reference only. A unit's tempera-
ture/pressure 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 prob-
lems, it is recommended that you follow the
"Pointers" in the first column of the General
Troubleshooting Guide. 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 sys-
tem.
