<Other points to note>
1
Cooling operation under low outside temperature conditions
1) If pressure falls to extremely low levels, indoor units may be shut down via freeze prevention control based
on the indoor TC sensor.
2) If pressure falls to extremely low levels, frequency may be reduced via cooling capacity control.
3) When the discharge temperature sensor reading falls below 60°C, the frequency may be increased above
the level called for by the command received from the indoor unit.
2
PMV (Pulse Motor Valve)
1) When the power is turned on, PMVs generate a tapping sound as they are initialized. If this sound is not
heard, there is a possibility of faulty PMV operation. However, in a noisy environment, it may simply be
drowned out by ambient noise.
2) Do not separate the actuator (head section) from any PMV during operation. It may result in an inaccurate
opening.
3) When transporting (relocating) the set, do not, under any circumstances, keep the actuator separated. It
may damage the valve by causing it to close and exposing it to pressure from sealed liquid.
4) When reattaching the actuator after its removal, push it in firmly until a click sound is heard. Then, turn the
power off and back on again.
