Manual

Instrucdons:
1. Measure suction pressure and deter-
mine evaporator-refrigerant temperature
on R410A scale of low-side gauge.
2. Measure suctionqine temperature on
suction line of the unit.
3. Measure outdoor and indoor tempera-
tures.
4. Determine from the table what the
superheat should be for the indoor and
outdoor temperatures.
5. Adjust charge if needed. Be sure unit is
running at stabilized condition.
Example of typical system operations:
80°F DBi50% RH Indoors
82°F DB Outdoors
140 (49 ° F Saturated Temperature)
Refer to supplied superheat chart (16 ° F)
70° F Indoors
Note:
47° F Outdoors
350/375 (107/112 ° F Saturated Temperature)
10-15° F
When the system is in heat cycle, the refriger-
ant charge is checked by using the liquid sub-
cool method. Liquid sub-cool is the temperature
below the high side pressure at its saturation
temperature.
