Note on Adding Refrigerant
Unele sisteme necesita incarcare suplimentara in functie de lungimile tevii. Lungimea standard a tevii
Some systems require additional charging depending on pipe lengths. The standard pipe length varies
variaza in conformitate cu reglementarile locale. De exemplu, in America de Nord, lungimea standard
according to local regulations. For example, in North America, the standard pipe length is 7.5m (25').
a tevii este de 7,5 m (25 '). In alte zone, lungimea standard a tevii este de 5m (16 '). Agentul frigorific
trebuie incarcat de la orificiul de service de pe supapa de joasa presiune a unitatii exterioare. Agentul In other areas, the standard pipe length is 5m (16'). The refrigerant should be charged from the service
frigorific suplimentar care trebuie incarcat poate fi calculat folosind urmatoarea formula:
port on the outdoor unit's low pressure valve. The additional refrigerant to be charged can be
calculated using the following formula:

For R290 refrigerant unit, the total amount of refrigerant to be charged is no more than:
387g(<=9000Btu/h), 447g(>9000Btu/h and <=12000Btu/h), 547g(>12000Btu/h and <=18000Btu/h),
Pentru unitatea frigorifica R290, cantitatea totala de agent frigorific care trebuie incarcata nu este mai
632g(>18000Btu/h and <=24000Btu/h).
mare de: 387g (<= 9000Btu / h), 447g (> 9000Btu / h si <= 12000Btu / h), 547g (> 12000Btu / h si <=
18000Btu / h), 632g (> 18000Btu / h si <= 24000Btu / h).
CAUTION
PRUDENTA: NU amestecati tipurile de agent frigorific.
