Refrigerant pipe before EEV kit or without EEV kit
The pipe work can be touching but not crushing the insulation.
When the pipes are touching, use thicker insulation.
Refrigerant pipe after EEV kit
Keep a 10mm separation of pipes after the EEV.
In case of small gap between gas and liquid pipe, use thicker
insulation .
Install the insulation not to be get wider and use the adhesives
on the connection part of it to prevent moisture entering.
Wind the refrigerant pipe with insulation tape if it is exposed
to outside sunlight.
Install the refrigerant pipe respecting that the insulation does
not get thinner on the bent part or hanger of pipe.
