17 SEER SINGLE STAGE HEAT PUMP CHARGING PROCEDURE (R410A)
NS17H24S
CHARGE BY WEIGHT:
1 - THE CONDENSER UNIT IS FACTORY CHARGED WITH R410A
2 - THE RATING PLATE LISTED CHARGE AMOUNT IS FOR 15 FEET OF LINE SET
3 - ADD 0.6 OZ OF FREON FOR EVERY ONE FOOT OF LINE SET OVER 15 FEET
4 - REMOVE 0.6 OZ OF FREON FOR EVERY ONE FOOT OF LINE SET UNDER 15 FEET
CHARGE BY SUBCOOLING (COOLING MODE):
1 - IF AMBIENT TEMPERATURE IS ABOVE 65ºF, CHARGE THE SYSTEM IN COOLING MODE
2 - THE SUBCOOLING METHOD IS USED FOR SYSTEMS WITH INDOOR TXV
3 - START THE SYSTEM IN COOLING AND LOWER THE THERMOSTAT SETTING TO MINIMUM SETTING
4 - CHECK AIR FLOW AND RUN THE SYSTEM FOR 20 MINUTES FOR STABILIZATION
5 - THE VALUES LISTED IN THE TABLE BELOW ARE BASED ON 70 TO 80ºF INDOOR RETURN AIR TEMPERATURE
6 - ADJUST CHARGE TO MEET THE SUBCOOLING LISTED UNDER “COOLING” FOR THE LISTED INDOOR MATCH
CHARGE BY SUBCOOLING (HEATING MODE):
1 - IF AMBIENT TEMPERATURE IS BELOW 65ºF, CHARGE THE SYSTEM IN HEATING MODE
2 - ALL HEAT PUMPS HAVE FACTORY INSTALLED OUTDOOR TXV
3 - START THE SYSTEM IN HEATING AND RAISE THE THERMOSTAT SETTING TO MAXIMUM SETTING
4 - CHECK AIR FLOW AND RUN THE SYSTEM FOR 20 MINUTES FOR STABILIZATION
5 - THE VALUES LISTED IN THE TABLE BELOW ARE BASED ON 65 TO 75ºF INDOOR RETURN AIR TEMPERATURE
6 - ADJUST CHARGE TO MEET THE SUBCOOLING LISTED UNDER “HEATING” FOR THE LISTED INDOOR MATCH
7 - IF FEASIBLE, DOUBLE CHECK THE FINAL CHARGE LEVEL DURING THE COOLING SEASON
OPERATING PRESSURES CHECK:
1 - THE PRESSURE VALUES LISTED BELOW ARE NOT INTENDED FOR CHARGING, BUT TO CONFIRM PROPER SYSTEM
OPERATION
2 - THE PRESSURE VALUES CAN VARY BASED ON THE DIFFERENT INSTALLATONS
