Copper tubing for connecting the outdoor unit to the indoor unit is available in kits which contain the narrow and wide
tubing, fittings and insulation. Consult your nearest sales outlet or air conditioning workshop.
1-4. Type of Copper Tube and Insulation Material
If you wish to purchase these materials separately from a local source, you will need:
1. Deoxidized annealed copper tube for refrigerant tubing as detailed in Table 2.
Cut each tube to the appropriate lengths 1' to 1'4" (30 cm to 40 cm) to dampen vibration between units.
2. Foamed polyethylene insulation for the specified copper tubes as required to precise length of tubing. Wall thickness
of the insulation should be not less than 5/16" (8 mm).
3. Use insulated copper wire for field wiring. Wire size varies with the total length of wiring. Refer to 3-7. Wiring
Instructions for details.

and regulations before
obtaining wire. Also, check
any specified instructions or
limitations.
