1. This unit is intended to be installed in a location that is 10,000 feet
(3000 meters) above sea level or lower.
2. Locate unit away from windows, patios, decks, etc. where unit
operation sound may disturb customer.
3. Ensure that vapor and liquid tube diameters are appropriate for unit
capacity.
4. Run refrigerant tubes with no bends with centerline bend radius less
than 2.5 times the external pipe diameter.
5. Leave some slack between structure and unit to absorb vibration.
6. When passing refrigerant tubes through the wall, seal opening with
RTV or other pliable silicon-based caulk. (See Fig. 1.)
7. Avoid direct tubing contact with water pipes, duct work, floor
joists, wall studs, floors, and walls.
8. 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).
9. Ensure that tubing insulation is pliable and completely surrounds
vapor tube.
10. When necessary, use hanger straps which are 1 in. (25 mm) wide
and conform to shape of tubing insulation. (See Fig. 1.)
11. Isolate hanger straps from insulation by using metal sleeves bent to
conform to shape of insulation.
12. Provision shall be made for expansion and contraction of long runs
of piping.
13. Piping and fittings shall be protected as far as possible against
adverse environmental effects. For example, the accumulation of
dirt and debris.
14. Piping should be installed to reduce the likelihood of hydraulic
shock damaging the system.
15. Certified piping and components must be used in order to protect
against corrosion.
16. Flexible pipe elements shall be protected against mechanical
damage, excessive stress by torsion, or other forces. They should be
checked for mechanical damage annually.
17. Piping material, routing, and installation shall be include protection
from physical damage in operation and service, and be in
compliance with the national and local codes and standards of the
installation site.
18. When setting up refrigerant piping, precautions shall be taken to
avoid excessive vibration or pulsation
