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.
If you wish to purchase these materials separately from a local source, you will need:
1.Deoxidized annealed copper tube for refrigerant tub- ing 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.
Table 2
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 5. Wiring Instructions for details.
CAUTION | Check local electrical codes | |
and regulations before | ||
| ||
| ||
| obtaining wire. Also, check | |
| any specified instructions or | |
| limitations. |
