gas pulsations from improper installation of equipment.

1. Locate unit away from windows, patios, decks, etc. where

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 un-

necessary turns and bends.

bration.

5. When passing refrigerant tubes through the wall, seal open-

ing with RTV or other pliable silicon--based caulk. (See Fig.

a rigid wire or strap which comes in direct contact with
tubing.(See Fig. 1.)

rounds vapor tube.

9. When necessary, use hanger straps which are 1 in. wide and

conform to shape of tubing insulation. (See Fig. 1.)
