Question about Fujitsu 18C1 Air Conditioner

I bought and installed an ASU9RLQ that had been

I bought and installed a Fujitsu ASU9RLQ mini-split that had been installed and used for approximately 6 months. It is at capacity on refrigerant and the electrical is installed correctly. However, I get no response when trying to activate the unit with the remote. I am beginning to suspect that the remote is the wrong one. It is an AR-JW5. Can you tell me if this is the correct remote for this unit or should the unit operate with it? Thank you.

Install new batteries, aim it at the unit and press the power button. You should hear a beep or see a green signal. If not, try to command the fan to come on.

I have a fujitsu aou24rml that i am installing in my house and the tag on the unit says 230/208 volts but the terminal block only has L and N witch i think is for 110 volt

Based on the specs that I could find, that unit requires 208/230 volts. Are you sure you are looking at the correct terminal block. It should be more like L1/L2. Do you have the install manual and does it tell where to hook up the supply voltage?

What is the hourly labor rate 2 install this unit

Trades will be very reluctant to give you an hourly rate on split system install as this would deplete the profitability. It depends on the installation, a simple back to back install would take around 3 hours with electrical connection to switchboard. It also depends on brick or fibro walls. Most installations are around 500 Aus dollars total price with the longest time frame of around 4 hours

I am trying to replace the fan on a Fujitsu ASU9RLQ Mini-split (I have the replacement unit). I have the front cover over the Mini-split; how do I get access to the existing fan to replace it?

This is from Friedrich support and I believe yours is similar. The whole bottom of the unit should come down after you remove the outside shroud.

To take the blower motor out:The technician would do the following:1. disconnect the power2. remove all front cover3. disconnect all wires at the terminal block at the unit4. DISCONNECT ALL WIRES AT THE BOARD. take out the control board5. remove the drain hose at the back6. REMOVE 2 SCREWS ON THE LEFT SIDE OF UNIT7. REMOVE 1 SCREW ON THE RIGHT FRONT AT BOTTOM8. PULL DOWN FIRMLY down

Fujitsu, Mitsubishi, Sanyo mini-split indoor fan motors operate continuoulsy. The room-temperature sensor is inside the unit, so the fan motor needs to circulate air continuouly to sense room-air temperature. This is normal operation.
