Safety Requirements
WARNING
ELECTRICAL
SHOCK,
FIRE,
OR
EXPLOSION HAZZARD.
Do not touch the unit or the controller if your
hands are wet.
DO NOT spray water on the indoor unit for
any reason.
Do not replace a fuse with a fuse of a
different rating.
Do not use a jumper wire to replace a fuse.
Do not insert your hands, tools or any other
item into the air intake or air outlet at either
the indoor or outdoor unit.
Do not allow children to operate the system.
CAUTION
To ensure proper system performance and reliability,
Lennox does not recommend operation of VRF systems
during any phase of construction. Construction debris,
low temperatures, harmful vapors, and operation of the
unit with misplaced filters can damage the units. Failure
to follow these guidelines will result in the warranty be-
ing voided.
Note -
Only Lennox VRF indoor units will work with Lennox VRF outdoor units and associated mechanical equipment.
Lennox Mini Split indoor units are similar in appearance but must not be connected to a Lennox VRF refrigerant circuit.
Please refer to model numbers to confirm compatibility. Model numbers for Lennex VRF units start with a “V” and model
numbers for Lennox Mini-Splits start with a “M”.
System Piping
CAUTION
VRF system piping is customized for each installation. The LVSS (Lennox VRF Selection Software) 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.
