unit operation sounds may disturb customer.

2. Ensure that vapor and liquid tube diameters are appropriate

to capacity of unit.

3. Run refrigerant tubes as directly as possible by avoiding

unnecessary turns and bends.

a rigid wire or strap which comes in direct contact with
tubing. (See Fig. 3.)
