Optional Distribution Joint Kits - Sanyo Classic PACi Serie Instrucciones De Instalación

CAUTION
1. This unit requires no additional refrigerant charge up to
tubing length 30 m. In case of more than 30 m, additional
refrigerant charge is required. Refer to Tables 1-9 and
1-10.
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 unit).
WARNING
Always check the gas density for the room in which the unit
is installed.
■ Check of limit density
When installing an air conditioner in a room, it is necessary to
ensure that even if the refrigerant gas accidentally escapes, its
density does not exceed the limit level.
If the density might exceed the limit level, it is necessary to
set up an opening between it and the adjacent room, or to
install mechanical ventilation which is interlocked with the leak
detector.
(Total refrigerant charged amount: kg)
(Min. indoor volume where indoor unit is installed: m
< Limit density 0.3 (kg/m
The limit density of refrigerant which is used in this unit is
3
0.3 kg/m (ISO 5149).
The shipped outdoor unit comes charged with the amount of
refrigerant fixed for each type, so add it to the amount that
is charged at the field. (Refer to the unit's nameplate for the
amount of charged refrigerant at shipment.)
Minimum indoor volume & floor area relative to the amount
of refrigerant are roughly as given in the following table.

CAUTION
Pay special attention to any location, such as a basement
or recessed area, etc. where leaked refrigerant can collect,
since refrigerant gas is heavier than air.
