Installation Requirements

- Purchase equal lengths of both
tubes and insulation required.
Cut the appropriate tube lengths,
30 to 40 cm (12 to 16 in.) longer
on each one to deepen vibration
between units. Wall thickness of
copper tube should be 0.8 mm
(0.0314 in.).
Both tubes must be well
insulated with proper insulation
materials.
- The length of wiring will
determine the wire size. See
local codes, refer to section of
electrical installation.
