Just installed piping over the weekend..
Is this ok?


The link shows an insulated pipe photo at the FCU. The FCU consist of the evaporator coil with 2 ends, one incoming and another outgoing. The incoming pipe is smaller, carrying liquid refrigerant while the outgoing pipe is larger, carrying refrigerant gas back to the condenser.

Both these pipes are placed together in one insulation inside the FCU. It is normal for installer to group both the smaller and larger pipe from the condenser together in one insulation as it get nearer to the FCU to joint to the respective pipes in the FCU that are in one insulation.

It is good practice to observe the installer during installation to ensure that the pipes before this grouping into one insulation are actually individual insulated pipes. This grouping should be as short as possible. There is no standard to date as to the length of this grouping, it should be done just to allow the pipes to fit nicely within the FCU. Two individual pipes may likely be too large for the available space within the FCU.

The above are my opinion and hope that they are helpful.
