Table of contents Installer and user reference guide 3 RXMLQ8 + RXYLQ10~14T7Y1B* VRV IV system air conditioner 4P543427-1A – 2020.10 11.2.5Symptom: The … Calculating the additional refrigerant charge Parameter [D] Indoor unit FXMQ type NOTE capacity The refrigerant charge of the system must be less than 210 lbs. 5.While still in vaccum with the right calculations charge the gas and you should not have any worries. View Profile View Forum Posts View Forum Threads Professional Member* Join Date Jul … Daikin’s Commission With Confidence service includes the supply of R410A refrigerant trim charge is guaranteed as part of a commissioning package for a set fee. 2. record of additional refrigerant charge amount and result of leak check operation request for the indication of additional refrigerant charging and leak detection operation result be sure to fill out the blanks, which are needed for after-sale services. The automatic refrigerant charge function automatically determines the optimal amount of refrigerant to be charged. The RXYQ-P7 units can be combined with Daikin VRV indoor units for air conditioning purposes, and suitable for R410A. About VRV. 4.All the precharged gas is for the outdoor heat exchanger not for the additional feild pipe added by the engineers. Depending on the amount of charge you may have to put it in additional charge mode. Page 30: Calculating The Additional Refrigerant Charge 14 .2 . Any presence of air or other foreign sub-stance in the refrigerant circuit could result in abnormal pres-sure rise or rupture, resulting in injury. This technology circulates only the minimum amount of refrigerant needed at any one time and enables individual climate control of air conditioning zones. type (100 kg). • When installing or relocating the system, keep the refrigerant circuit free from substances other than the specified refrigerant (R410A) such as air.
