Shotang

Shotangasked

Hello, I have the Z12RKR and the Z09RKR installed in the kids bedrooms 3 years ago. The first nights we used them they would not cool consistently. It would start off at a correct temp, then warm up over the night. We followed the instructions carefully. They were on cool mode, econavi off and fan on auto. After trying multiple combinations we were never able to get the rooms to stay at a constant temp. We rang the installer who advised that we shouldn't use auto, as it doesn't keep the room consistency cool, but to use a low fan setting. Which we have been successfully using since.

The other day I was cleaning the filters and noticed huge amounts of mould growing inside the unit. The last clean and service was conducted 15 months ago. I rang the installer who stated using low fan settings typically contributes to mould growing, and seemed to think it just needed a clean and service.

I feel like this is a no win situation if I follow what has been advised. What settings should I realistically be using to keep the unit clean and actually cooling at night? Has anyone else encountered this?
I feel auto at night should work when econovi is off?

I understand all units need regular servicing. However I cannot believe this amount of mould would grow in such a short amount of time unless something is wrong. None of our other brand of air conditioners we have purchased in our properties over the years have behaved like this. Thank-you.

Hi Shotang, thank you for your query. Mould build up is due to the environment. Running the unit on any particular mode will not add to this or remove it. We would recommend frequent cleaning of the filters, but also of the whole unit.
Auto will detect the temperature and the unit will ramp down accordingly, and when the temperature rises, turn back on. This is why it would have been suggested to use the product in manual mode, to have the unit consistently running the whole night.

We would recommend at the end of each summer running the unit on a heating cycle (if it isn't used on heat in winter) to dry up any stored moisture within the unit.

Can you please advise what is the highest possible level this unit may be installed on the the wall? ie. What is the necessary clearance from the top of the unit to the ceiling? As I've noticed the unit expands outwards (not so ,much upwards) during operation

thanks

This is a question for the installer or electrician but mine is installed quite high up with about a open hand space to the ceiling. I was told this will be ok and I hope it doesn’t cause any issue down the track.

Thanks, is that for this same Fujitsu designer model? When it operates, the front panel extends forwards and up. Is your hand distance enough for this?

I have the 5kw and the unit takes 10 minutes to warm up (apparently normal) but the real frustration is that after blowing warm air for approx. 30 minutes the unit goes into some sort of sleep mode with a whirring/gurgling noise. Nothing I do gets the unit to start heating again - ive changes the modes and increased the temp but it just continues blowing the faintest amount of warm air out for over 1.5 hours while the room gets cold. Panasonic technician has come and said this is all “normal” including the ridiculously loud unit outside. Does anyone else think this sounds normal?

Thanks
Sam

No, it's certainly not. 5 minutes warm-up would be (just) normal, certainly not that is stops heating after 30 minutes. This sounds much worse than my unit. It suggests to me that Panasonic has had a problem with early R32 units and won't admit to it. Since your case appears to be much more clear-cut than mine, I'll suggest to take it to Fair Trading and the tribunal if it has to be. If what you write is true, you'll win your case. Please keep me posted, I'm happy to toe your line in regards to noise issues.

ECONAVI Reverse Cycle Inverter CS/CU-Z28RKR (8kW)

I have the 8kw unit and am finding it slow to respond when switching to heat mode in the morning. It takes at least 10minutes to fire up. My previous model Panasonic is almost instant. Also some features such as the air swing are not activating and it seems to hunt around the set temperature. The unit was just installed. Any suggestions?

It won't start until the air coming out of it is pretty warm, so perhaps your external unit is in a very cold place in the morning?

You should check what settings you have turned on, as well, cos the Econavi and iAutoX are designed to adapt the temperature based on light/movement/... . The air swing should work as soon as air is flowing. If it isn't and you definitely have it set to Auto, then perhaps the unit is faulty.

Hi coolme,
My unit is also installed in the bedroom with the tubes going straight through the plasterboard through to the brick wall to the outdoor unit. It looks very clean and no tubes or wires can be seen in the bedroom. Outdoor unit is wall mounted. Hope this helps

Kim
Kim

go through the wall is cheaper,
it will be more expensive to go through the celing, as water need a pump to drain

Have you rang Panasonic themselves and asked for their advice? They must have reps or someone that can answer that one properly.

It could be the drain from the indoor unit is not installed correctly. Was the the system vac pumped and installed to the Panasonic specifications?

Hmm, I've never really noticed mine gurgling, unlike my ducted, roof mounted evaporative cooler

blissin

Actually - I realise mine also makes gurgling noises, but only just before it starts pumping out hot air and it stops then. Think I have heard it in other units too ..maybe its just the gas circulating round. It works great anyway

ECONAVI Reverse Cycle Inverter CS/CU-Z24RKR (7kW)

Is the remote operation erratic? On our new unit you have to often press the buttons multiple times for the Aircon unit to respond to the command (with a beep), other times it responds first time. Any other owners experienced this?

with my unit the response time does seem slow, from when you press the button on the remote, to actual doing ..

wirh the air swing it goes through a cycle, press the swing function..... wait !!! and it might start the remote swinging up and down automaticly, or it might start at a starting point that's fixed, I cant remember what happens first now, but slowly go through the cycle pressing the swing button, wait for the beep, then wait a lil more to see what the unti does, I found that I was pressing buttons to fast and the unit seemed to be doin all sorts of things on it's own, I slowed the fingers daow and it works as it should now.

Funny you should mention this on my son's unit the earlier model I have to do this to turn it off. I actually have to press it a couple of times for it to completely turn off ie takes two beeps. I will have to look into this whilst it is still under warranty - thanks for the reminder :)

I have the 8kw model and also Finding slow responses and the unit seems to get confused about it's mode of operation. Also slow to start in heat mode. At least 10mins warm up time.

What is the maximum length of gas tube between the external and internal unit?

1 answer

Hi Margaret, we have high ceilings and the external unit was secured on the ground so we needed approx 5M of piping- it cost us an extra $80 for installation. The installer told us the max piping length is 10M. Double check with Panasonic an approved installer to make sure so that you get max benefit out of your investment. Cheers!!
