System Piping

CAUTION
VRF system piping is customized for each installation.
The LVSS piping report is an engineered design that must
be followed. The piping diagram or diagrams included
within the LVSS report have been prepared based on
the information provided to the Lennox VRF applications
department.
When the indicated lengths change from the figures
stated within the report, it is imperative that prior to the
commencement of the refrigerant pipe work installation,
Lennox VRF applications department are informed of
these proposed changes.
Upon receipt of this new information the Lennox VRF
applications department will confirm any changes that
may be applicable to this installation. If changes are
required, a new piping diagram will be produced and will
supersede all other previously provided documents.
Failure to provide this information regarding changes
to the original design may lead to insufficient capacity,
equipment failure, warranty being made void and the
refusal to commission the system.
