unit operation sound may disturb customer.

2. Ensure that vapor and liquid tube diameters are

appropriate for unit capacity.

3. Run refrigerant tubes as directly as possible by avoiding

unnecessary turns and bends.

opening with RTV or other pliable silicon- based caulk.

(See Fig. 1.)

6. Avoid direct tubing contact with water pipes, duct work,

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

tubing.(See Fig. 1.)

8. Ensure that tubing insulation is pliable and completely

surrounds vapor tube.

mm) wide and conform to shape of tubing insulation. (See

Fig. 1.)

10. Isolate hanger straps from insulation by using metal

sleeves bent to conform to shape of insulation.
