Haier Wine Cellar WS200GS -- Need Max r134a Refrigerant Volume

Haier Wine Cellar WS200GS

I've received a Haier undercounter wine chiller, model WC200GS, for servicing. The tech label is missing.

No tech info at Haier website for this model.

Anyone know the maximum ounces of r134a refrigerant this thing requires? For obvious reasons, please don't guess.

The only one of that brand wine chiller I worked on the label was on back. Also the parts were not available. These are rare to see in my area. It was under 5 years old.

I cant find this one down here in aus to give you info

I just guessed.

I looked at two other older models of this type of dual zone wine fridge, both r143a. The average re is 1.5 to 2.1--there's likely a greater range but my sample size was pretty dinky. Prudence says it's better to be undercharged than over. Nevertheless, I drew in 2oz and watched for low-side pressure to be nominal, frost on the low side at the compressor, and unusual behavior with the thermostat. Hopefully my blind recharge will suffice.
