Indicator Lights - Acson WM Serie Installationsanleitung

Additional charge
The refrigerant is pre-charged in the outdoor unit. If the
piping length is less than 7.62m (25ft), then additional charge
after vacuuming is not necessary. If the piping length is more
than 7.62m (25ft), then use the additional charge valve as
indicated in the table.
Charge operation
This operation must be done by using a gas cylinder and a
precise weighing machine. The additional charge is topped-
up into the outdoor unit using the suction valve via the ser-
vice port.
• Remove the service port cap.
• Connect the low pressure side of the charging gauge to
the suction service port center of the cylinder tank and
close the high pressure side of the gauge. Purge the air
from the service hose.
• Start the air conditioner unit.
• Open the gas cylinder and low pressure charging valve.
• When the required refrigerant quantity is pumped into
the unit, close the low pressure side and the gas cylinder
valve.
• Disconnect the service hose from service port. Put back
the service port cap.
IR signal receiver
When an infrared remote control operating signal has
been transmitted, the signal receiver on the indoor unit
will make a <beep> sound to confirm acceptance of the
signal transmission.
Cooling unit
The table shows the LED indicator lights for the air condi-
tioner unit under normal operation and fault conditions.
