Getting a/c serviced and engineer needs to locate the Pump Relay Box. Should only be one I'm told

The manual doesn't mention it - just the Sea Water Pump (one for each a/c unit)- but even this is located where it should be.

Anyone know where it might be?
Cheers

The pump itself from memory is in the engine room under the sole.

I am not sure why he would need to access the control box.

From memory ( and i sold it some time ago) there are control boxes adjacent to the compressors which are (a) under the steps in the saloon and (b) under the sofa - forward area.

I suspect one is the master that controls the pump but my memory does not stretch back that far. There were as I recall no boxes in the engine room.

I you look at the AC manuals it will show how it is wired ( or a typical installation) and what the pump connects to ... but back to what does he need access to it just to service it?
 
Many thanks jrudge
Presume the sole are the floor hatches - maybe that's why he didn't see it (he has done GenSet)
Not sure why he wants to see it but he asked !
The manual I have is off a newer T40 but doesn't mention the PRB
Cheers again

So the reason is :
The pump is not getting a live feed when air con is running. If the pump is not running there is no cooling water flow and the compressor will shut down on overheat - which is whats happening. Needs to check as cant carry out a service if system is not functioning.

Lets hope we can find it easily
 
Location will vary depending on whether you've got oe or aftermarket aircon. On mine, the compressor is under the saloon stairs, and that's where the control box is. Mine is aftermarket.
