System Piping
CAUTION
VRF system piping is customized for each installation. The Lennox VRF Selection Software (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.
