Daikin info - please!

[aircon50]

Hi all,
1. I've just read with interest the thread regarding Daikin, and redeuction in customers etc.
2. And for that reason, I guess Daikin do not reply to web messages sent via the extranet any more. The units noted below do not appear in the document library, possibly because they are too old.

If that is the case, can any of you guys help, please.

I haven't seen the system yet, but the information supplied by the client is that the units are, Ext; REQ100B8V3B/ Int;FDEQ100B8V3B. Problems are error codes JC and H7.

Does anybody have a Service Manual to cover these units - BIG please?

Many thanks

Graham

It seems like outdoor unit has problem.

JC : Suction pipe pressure sensor error

H7 : Overload or over current sensor of fan motor is abnormal.

Hope that will help you.

Hi guys

Thanks for your replies. I have service manual for B7, this is exterior B8, (with B7 interior) - can't find B8 manual anywhere!
Been to the system today - Don't know why showing code H7 - nothing wrong with fan motor! However error code JC readily understood. Refrigerant leak at suction connection to interior unit! I bet it was easy to get to without a ceiling in place......
Now have problem with LG wall split, but will start new thread.....
Best regards, Graham

The H7 could relate to one speed not working on the Daikin, normally medium speed, won't show up unless you watch if for ages!!
