MSZ-GL25VGD (2.5kW)

I bought two GL25 units for two bedrooms of my house. The cooling starts to work very quickly, but the startup of heating takes more than 10 mins. If its normal or a design problem?

I think it's normal. I have a same issue.


Hi. Depending upon the ambient temperature, it may take longer to heat the indoor unit coil to the right temperature prior to starting the fan. It will also not run the fan above low speed until it is satisfied it can keep a certain air temperature.
All inverter units start their compressors at the lowest speed and can take around 7-8 minutes to reach normal full speed. The other factor which can effect heating startup is the length of pipe run between indoor & outdoor unit. The longer the run, the longer it takes to reach "normal" operation. Hope this helps.

Can someone please confirm whether this 2.5kW unit has only one vent panel at the top and there is a gap at the bottom or it supposed to have two vent panels?

I've just had one installed today in my office at work and it definitely has 1 panel only, leaving a gap at the bottom. It's a little weird actually, but as I haven't even turned it off yet, I hadn't noticed myself. It's early days for me, but I'm thrilled so far. It's doing its job very well, and very quietly.
