toshiba accumilator problems

[sid]

good afternoon
i'm sorry for the spelling, but i'm working at an old toshiba rav 200 uh unit which has a few leaks on the accumilator due to it being on the coast. i've just been to hrp and they are having problems getting me a new one.
i'm just wondering would it be ok for me to cut it out of the system and re pipe without having any accumilator.
i look forward to hearing from you soon

Hi Sid

I'd say no. Could you measure it and get a similar sized one from a component manufacturer such as Henry, Heatcraft, or Esk Schultze (Nrs, Rpw,Dean&Wood) If the original is obselete.

I'd say no, if its a heat pump, on off cycle defrost liquid will slug the compressor

If you look at any manufacurers split systems technical specification you will normally find that the cooling only model will not have a suction accumulator unless precharged for long pipe run.
But the same heat pump model will have suction accumulator. This is needed to prevent liquid back to compressor.

Hi Sid,

You'll have trouble finding an accumulater for the RAV-200UH because a) that model doesn't exist and b) 'UH' in Tosh talk is a cassette and accumulators are fitted to outdoor units.

So I'd guess you either have an RAV-200KH hi-wall system or an RAV-260UH 4-way cassette system.

Which in turn means you either have an RAV-200AH or an RAV-260AH(8) outdoor unit.

Use part number 43148116 for the RAv-200AH or 43148114 for the RAV-260AH(8).

Any Toshiba distributor should be able to check availability and prices.

Don't run the system without an accumulator the risk is 'liquid carry over' ie compressor trying to pump liquid refrigerant with dire consequenses.

Hope this helps

had this problem myself. i just used my angle grinder to take off the rust then i silver soldered over area (the rust had eaten through steel casing causing a pin hole)

i know its not ideal but it held a 400psi strength test and 270 psi 24hr test and it was ok, it also only meant that unbit was down for 2 days (instead of weeks trying to source parts)
