3.Run refrigerant tubes as directly as possible by avoiding unnecessary turns and bends.

4.Leave some slack between the structure and the unit to absorb vibration.

5.When passing refrigerant tubes through the wall, seal the opening with RTV or other pliable silicon-based caulk. (See Fig. 3.)

6.Avoid direct lineset contact with water pipes, ductwork, floor joists, wall studs, floors, and walls.

7.Do not suspend refrigerant tubing from joists and studs with a rigid wire or strap which comes in direct contact with the tubing. (See Fig. 3.)

8.Ensure that tubing insulation is pliable and completely sur- rounds the vapor tube.

9.When necessary, use hangar straps which are 1 in. (25mm) wide and conform to the shape of the tubing insulation. (See Fig. 3.)

10.Isolate the hangar straps from the insulation by using metal sleeves bent to conform to the shape of the insulation.

If refrigerant tubes or indoor coil is exposed to atmospheric conditions for longer than 5 minutes, it must be evacuated to 500 microns to eliminate contamination and moisture in the system.

To prevent compressor damage DO NOT bury more than 36 in. (914mm) of refrigerant tubing. If ANY tubing is buried, provide 6 in. (152mm) vertical rise at service valve.

OUTDOOR UNITS CONNECTED TO FACTORY-APPROVED INDOOR UNITS Ð Outdoor unit contains correct system refrig- erant charge for operation with indoor unit of the same size when connected by 15 ft (4.55m) of field-supplied or factory-accessory tubing. Check refrigerant charge for maximum efficiency.

REFRIGERANT TUBING Ð Connect tubing to fittings on out- door unit vapor and liquid service valves. (See Fig. 2.)

Relieve pressure and recover all refrigerant before system repair or final unit disposal to avoid personal injury or death. Use all service ports and open all flow-control devices, including solenoid valves.
