Note: If calculated subcooling value is lower than the design
subcooling value, please add refrigerant. Repeat the steps above.
Note:Make sure the superheat value of suction valve
should be above 12ºF, if the value is lower than this,
indoor TXV should be adjusted.If the temperature is
higher than 18ºF, we suggest to adjust indoor TXV.
Repeat the steps above.
(If to adjust TXV ,steps of
adjustment are shown on
separate sheet , and
repeat this step.)
