for unit capacity.
3. Run refrigerant tubes as directly as possible by avoiding un-
necessary turns and bends.
4. Leave some slack between structure and unit to absorb vi-
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).
8. Ensure that tubing insulation is pliable and completely sur-
rounds vapor tube.
9. When necessary, use hanger straps which are 1 in. wide and
conform to shape of tubing insulation (see Fig. 1).
10. Isolate hanger straps from insulation by using metal sleeves
