Installation Requirements

Table 2 : For Convertible (MCX), Concealed (MCD) and Hi-Wall (MCW, Frio) Indoor units

1. Copper Tubing

Copper tubing, fittings and
insulation to interconnect the
suction (S) (wide tube) and liquid
(L) (narrow tube) refrigerant lines
between the indoor and outdoor
units can be purchased locally.
It is necessary to purchase the
following items:

- Purchase equal lengths of both
tubes and insulation required.
Cut the appropriate tube lengths,
30 to 40 cm (12 to 16 in.) longer
on each one to deepen vibration
between units. Wall thickness of
copper tube should be 0.8 mm
(0.0314 in.).
Both tubes must be well
insulated with proper insulation
materials.

- The length of wiring will
determine the wire size. See
local codes, refer to section of
electrical installation.

2. Additional Materials

- Saddles or clamps to hold
refrigerant tubing.

- Insulated clamps or staples
for connecting wire.
See local codes.

- Refrigeration oil and tape
(armored).

- Putty or similar filter.
