INTRODUCTION AND RECOMMENDATIONS
NOTE: In some cases noise in the living area has been traced to
gas pulsations from improper installation of equipment.
1. Locate unit away from windows, patios, decks, and so forth,
where unit-operation sound may disturb customer.
2. Ensure that vapor- and liquid-tube diameters are appropriate to
capacity of unit. (See Table 1.)
3. Run refrigerant tubes as directly as possible by avoiding
unnecessary turns and bends.
4. Leave some slack between structure and unit to absorb
vibration.
5. When passing refrigerant tubes through the wall, seal opening
