ambients below 55°F, is to weigh in the charge in the heat-
ing mode.
2. Check liquid line temperature and pressure (at the OD
valves) to obtain a minimum of 10°F subcooling.
3. It is important to return in the spring or summer to accu-
rately charge the system in the cooling mode at outdoor
ambients from 55°F-120°F.
