Connect The Cable To The Indoor Unit - Panasonic WH-SDC0305J3E5 Installationshandbuch

Additional Precautions For R32 Models when connecting by fl aring
at indoor side
Ensure to do the re-fl aring of pipes before connecting to units
to avoid leaking.
Connections made between components of refrigerant
system shall be accessible for ease of maintenance.
Seal suffi ciently the fl are nut (both gas and liquid sides) with neutral
cure (Alkoxy type) & ammonia-free silicone sealant and insulation
material to avoid the gas leak caused by freezing.
Neutral cure (Alkoxy type) & ammonia-free silicone sealant is only to be
applied after pressure testing and cleaning up by following instructions
of sealant, only to the outside of the connection. The aim is to prevent
moisture from entering the connection joint and possible occurrence
of freezing. Curing sealant will take some time. Make sure sealant will
not peel off when wrapping the insulation.
Checking for gas leakage
•
Check for leakage of gas after air purging.
•
See the in the installation manual for the outdoor.
CUTTING AND FLARING
