Simply because I like things finished... I am
posting the results of the
shower gulper timer relay upgrade here. Thanks firstly to PaulinOZ for his help.
So on a four bedroom "charter" layout
Lagoon 450, the timer relays for each
hull are located in the Rear/Port and the Forward/Starboard bathrooms respectively. Yes the relays for both bathrooms in each
hull are together in the one bathroom.
Specifically they are in the under-basin cupboard (below sink) at the inside/right hand/bottom of the door frame. They are two red cubes (or are on mine).
They are held to the wooden door frame with a short Phillips
head screw each.
When the screws are undone grab the relay (red cube) in one hand, then reach underneath it with your other hand and grab tight to the plastic casing that holds the female
electrical connectors. Pull slowly but firmly to extract the red relays make blade connectors from the female connectors in the grey connection box.
In my case I was switching the 15 second
lagoon fitted relays out for multi-timer relays which have variable adjusting dials within them.
These dials are beneath two opaque plastic press fit caps on the top of the relay.
Pry each cap off (fingernail or flat blade screwdriver).
Inside each is a tiny adjustable dial. The dials themselves are pretty hard to see: I used my
iPhone camera, took stills and blew them up, to determine if there was a pointer as such on the adjustment slot (a small Phillips
head slot).
There is but it's hard to distinguish as it's a tiny arrow head on one end of one of the arms of the Philips head slots.
The multi timer relays come with a sheet detailing what settings are available.
I chose dial setting One and maximum.
Dial setting One denotes No Delay and a range of time possibilities from 5 seconds to 60seconds. With maximum therefore being 60 Seconds and minimum delivering five seconds.
Again, speaking for mine, the multi-timer relays arrive set to "nine" and "minimum.
You will need a very fine Phillips head screwdriver (a jeweller's number one or 2.5 to 3mm screw driver.)
To adjust the variable dial from minimum to maximum means turning it fully clockwise to its stop.
One of them is a stepped dial from zero to nine, the other is a slightly stepped but fully variable dial. This latter one is factory set to minimum.
To adjust the stepped dial I counted the steps back to zero then gently advanced one to be sure. (I believe you can advance through zero back to nine but can't be sure)
The result means if I press the black rubber capped button in the
shower cubicle to set the drain scuppering it will run without a delay from pressing for 60 seconds before I need to press it again (for another sixty seconds of drain action!)
In my case the relays didn't come with attaching brackets and so I had to resort to very high adhesion double sided tape (my fixer of last resort!)
That then. is the end of my sermon on egg-sucking for grandmas!
