Inverter Cover
IMPORTANT:

from unit with cover installed.
Installation Recommendations
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, etc. where unit
operation sound may disturb customer.
2. In noise sensitive applications (such as bedrooms), when a lineset is
mounted to ceiling joists or floor joists, the outdoor unit must be
located at least 10 ft (3.05 m) away. If this is not possible, create a
line set configuration with enough bends to provide 10 ft (3.05 m)
of total line set length outside the dwelling
3. Ensure that vapor and liquid tube diameters are appropriate for unit
capacity.
4. Run refrigerant tubes as directly as possible by avoiding
unnecessary turns and bends.
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
).
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
).
9. Ensure that tubing insulation is pliable and completely surrounds
vapor tube.
10. When necessary, use hanger straps which are 1 in. wide and
conform to shape of tubing insulation. (See
.)
11. Isolate hanger straps from insulation by using metal sleeves bent to
conform to shape of insulation.
