Fujitsu wall mount split
Hi , iv recently been called to site , they said indoor wall mount had frozen up on coils , checked when I got there and all seemed ok , there had been ice on coils as it was soaking on floor ... Checked pressures all seem ok , ran unit and ran ok .. But another call has come in and same thing happening , any ideas , out door unit has comp capacitor and fan capacitor , that's about it .. Checked indoor pcb etc , main relay all seem ok ?? This is in a kitchen and has NO controller and is basically turned on by fused spur , so no set points .. Any ideas fellas before I go back Monday

check drain/ condensate pump filter- had it where drip tray fills with water and causes freeze up, and also condensation forming under the drip tray- get a controller for it- last muppet may have had it set at 16 low fan .
also fitting a wall mount in a kitchen isnt the best- ideally a ducted unit using return air not from the kitchen and a remote sensor.

Re: Fujitsu wall mount split
If its really basic system and wired to be permanently on, maybe a defrost clock wired to stop the compressor would help?
Mostly found in Oxfordshire, UK :)

with most kitchens typical room temp is under 20 deg until they turn on every gas appliance to get it upto +30 deg then theyre in and out fridges- so it will be undersized- if theyre using the auto button on the unit it will run at 24 auto low fan, spend a day monitering it under normal circumstances- but dont let them offer u any food unless u checked the temps of the fridges first.
i refitted a walk in freezer door once at a post house hotel in chester- chef was happy with the work we did- offered us some food- waited in staff room - a plate of cheese and tomato butties turned up- not a big cheese fan so thats why they were stuffed between the radiators!!! haha
