WARNING
Always check the gas density limit for
the room in which the unit is installed.
1-11. Check of Limit Density
When installing an air conditioner in a room, it is necessary to
ensure that even if the refrigerant gas accidentally leaks out, its
density does not exceed the limit level for that room.
If the density could exceed the limit level, it is necessary to
provide an opening between the unit and the adjacent room, or
to install mechanical ventilation which is interlocked with a leak
detector.
(Total refrigerant charged amount: kg)
(Min. indoor volume where the indoor unit is installed: m³)
≤ Limit density 0.44 (kg/m³)
The limit density of refrigerant R410A which is used in this unit
is 0.44 kg/m³ (ISO 5149).
The shipped outdoor unit comes charged with the amount of
refrigerant xed for each type, so add it to the amount that
is charged in the eld. (For the refrigerant charge amount at
shipment, refer to the unit’s nameplate.)
Minimum indoor volume & oor area as against the amount of
refrigerant is roughly as given in the following table.
CAUTION
Pay special attention to any location, such as a basement, etc., where leaking refrigerant can accumulate,
since refrigerant gas is heavier than air.

Common solenoid valve kit
● Multiple indoor units under group control can utilize a solenoid valve kit in common.
● Categories of connected indoor unit capacities are determined by the solenoid valve kit.
Type of solenoid valve kit Total capacity of indoor units (kW)
CZ-P160HR3 5.6 < Total capacity ≤ 16.0
CZ-P56HR3 Total capacity ≤ 5.6
● If the capacity range is exceeded, use 2 solenoid valves connected in parallel.
