Installation

Condensate drain pipe and refrigerant tubes.
• Fasten the electric wires and refrigerant tubes together. Allow an
additional length to the electric wires for easy connection to the unit
connectors.
• Run refrigerant tubes so the condensate drain pipe is always
positioned at the bottom of the conduit. Connect the condensate
pipe to a proper drain using a flexible PVC pipe. Horizontal runs
between indoor unit and drain orifice must have a minimum 2% slope.
Note:
Do not kink or flatten the tubes. Avoid bends with a bending radius
of less than 100 mm. Do not bend copper tubes more than three
times at the same point. Do not remove flare fittings from unit tubes
before actually making the connections. Do not fasten the insulation
too tightly to the tubes with straps or tape.
