Low pressure switch stops the unit when the suction pressure decreases below its limit pre-set value. The reset
is automatic and it occurs only when pressure is higher than the device differential resetting value (see table
below).
Since the SCROLL compressors can function only in one rotating direction, this device controls that the phases
be correctly connected.
In case phases are not correctly connected, the machine will not start, a light will begin to flash in the relay and
on the panel the green light ALARM will be ON.
Warning: The machine must not be installed in narrow space, that could not allow an adequate spread of
the air coming from the outlet.
The external unit must not be installed in narrow spaces. The suction comes from the opposite side where the
motor fan is placed, while the discharge is set on the other side. The minimum distance between the discharge
and a wall is 3 meters.
