where 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.
4. Leave some slack between structure and unit to
absorb vibration.
5. When passing refrigerant tubes through the wall, seal
opening with RTV or other silicon-based caulk.
6. Avoid direct tubing contact with water pipes, duct work,
floor joists, wall studs, floors, walls, and any structure.
7. Do not suspend refrigerant tubing from joists and studs
with a rigid wire or strap which comes in direct contact
with tubing.
8. Ensure that tubing insulation is pliable and completely
surrounds vapor tube.
When outdoor unit is connected to factory-approved
indoor unit, outdoor unit contains system refrigerant charge
for operation with indoor unit of the same size when
connected by 15 ft. of field-supplied tubing. For proper unit
operation, check refrigerant charge using charging

the condensing unit can be installed from the property line.
Install on a Solid, Level Mounting Pad
The outdoor section is to be installed on a solid
foundation. This foundation should extend a minimum of
2" (inches) beyond the sides of the outdoor section. To
reduce the possibility of noise transmission, the foundation
slab should NOT be in contact with or be an integral part of
the building foundation.
