1. Tubing SizeOutdoor Unit
Single type
 
Refrigerant tubing between the indoor and outdoor units
should be kept as short as possible.
The length of the refrigerant tubes between the indoor
and outdoor units are limited by the elevation difference
between the 2 units. During tubing work, try to make both
the tubing length (L) and the difference in elevation (H1)
as short as possible. Refer to Table 1-2.

CAUTION
1. This unit requires no additional refrigerant charge up to 100 ft. tubing length.
In case of more than 100 ft., additional refrigerant charge is required. Refer to Table 
1-3.
2. In case of multi type installation, indoor units should be installed within the same 
room. If multi type indoor units are installed in different rooms, temperature control 
may develop problems because thermostat operation must follow the thermostat 
condition of 1 indoor unit only (the main...
