Home Air Conditioner. Problem?

[Pickles2]

We had a Daikin "Inverter" ducted A/C system installed about 3.5 yrs ago. The unit (outside) is a FDYQ160 fitted 15.5kw cool & 16.3kw heat. Our home is only about 15.5 sq, so the system works well, still does.
Just after it was installed, my neighbour pointed out that a lot of water was running out from under the unit. I rang Daikin, & they said that some installers never bothered to install "the drain". So I rang the installer & they fitted one,....didn't seem to be very substantial, just a small plastic pipe coming out between the two concrete slabe that the unit sits on.
Now the unit is still working brilliantly, hot & cold, but there is still water coming from under the unit,...it runs out the bottom onto the slab, & into the garden.
I've been told that this water loss is simply a working feature of the unit, & that they all do it?
An annoying aspect of this is that the original company that installed it went into liquidation. They are now operating under the same name, but a "different" company, use the same phone number, but won't come to look at it, even though it is still under warranty.
Anyway, I would appreciate anyones' views, as to the operational issue that I have,...maybe they all do it?
Thanks, Pickles.

Wouldn't the warranty be with Daikin, not the installer? Get onto the manufacturer and explain the situation. Jim

All air conditioning that are refrigerator not evaporated will have water as a by product. Two main things humidity and use. If it is humid and running in cold more you will get a lot of water from the inside unit. In heating mode you will get water from the outside unit this is normal. The thing is to get the drains right. That is your problem not the unit as such. I have people not fitting drains at all.

Thank you for your input.
So, what you're saying is that, at the moment, when the unit is heating, it's going to generate water, which will, as in my case, dribble out under the unit?...so, it's normal?
Thanks, Pickles.

Yep Pick. in heating thye outdoor unit it may go into de ice occasionally.

Whereabouts in Melb are you.

I could come and take a quick look if you want.

If you're still worried pack it up 10mm off the slab with some rubber waffle pads

Absolutely normal operation.

When in reverse cycle (heating) the outdoor coil becomes the evaporator and its working temperature is below the ambient air dew point, so condensation forms on the fins/coil.

This just drains away underneath the outdoor unit.

The amount of water increases during a defrost.

During the cooling cycle the indoor unit is the evaporator and the condensate drains into the gutter, (using a dedicated drain) or perhaps down the wall and outside.

Rick beat me to it.
Ideally the outdoor unit is in a garden so that the plants get the benefit of the condensate. Frankly the only time I bother to fit the little drain part is on the few occasions where you need to drain the condensate away from the area under the outdoor unit.
On the other hand, if the system is in cooling and there's water draining out of it, it's possible there's a problem. In cooling mode, any exposed parts of the larger pipe (around the valve on the outdoor unit usually) getting wet due to condensation is normal as well.

I have a Daikin split system in the apartment I'm staying in when working in Perth. Condenser unit is mounted outside on the balcony. There is almost always a trail of water from beneath the condenser to the floor drain in the centre of the balcony when the unit is running. I only ever use it to cool the apartment though - doesn't get cold enough in Perth to require using it as a heater.

There is sometimes some water during cooling,but no where near as much as there is when heating during cold ambient temperatures.If you look closely you may even see frost or ice on the outdoor unit coil during heating.

While cooling,particularly when the weather is humid,water will drip off the suction line,service valves,suction accumulater,etc that will cause a trail of water from the unit.Running the unit on a very cold setting will increase the water and even cause ice to sometimes form on some pipework,etc,and drip as it melts.
This is normal.
