3. GENERAL
This INSTALLATION MANUAL briefly outlines where and how to
install the air conditioning system. Please read over the entire set
of instructions for the indoor and outdoor units and make sure all
accessory parts listed are with the system before beginning.
3.1. Type of copper pipe and insulation
material
CAUTION
Refer to the installation manual for the outdoor unit for
description of allowable pipe length and height difference.
Diameter
Liquid pipe Gas pipe
6.35 mm (1/4 in.) 9.52 mm (3/8 in.)
CAUTION
Install heat insulation around both the gas and liquid
pipes. Failure to do so may cause water leaks.
Use heat insulation with heat resistance above 248°F
(120°C) Reverse cycle model only)
In addition, if the humidity level at the installation lo-
cation of the refrigerant piping is expected to exceed
70%, install heat insulation around the refrigerant pip-
ing. If the expected humidity level is 70-80%, use heat
insulation that is 15 mm (19/32 in.) or thicker and if the
expected humidity exceeds 80%, use heat insulation
that is 20 mm (25/32 in.) or thicker.
If heat insulation is used that is not as thick as specifi ed,
condensation may form on the surface of the insulation.
In addition, use heat insulation with heat conductivity
of 0.045 W/(m•K) or less at 68°F (20°C).
3.2. Additional materials required for
installation
A. Refrigeration (armored) tape
B. Insulated staples or clamps for connecting wire (See your
local electrical codes.)
C. Putty
D. Refrigeration lubricant
E. Clamps or saddles to secure refrigerant piping
