If you wish to purchase these materials separately from a local

to dampen vibration between units.
2. Foamed polyethylene insulation for copper tubes as
required to precise length of tubing. Wall thickness of the
insulation should be not less than 8 mm.
3. Use insulated copper wire for field wiring. Wire size varies
with the total length of wiring.
Refer to 4. ELECTRICAL WIRING for details.
CAUTION
Check local electrical codes and regulations before
obtaining wire. Also, check any specified instructions or
limitations.
