Frigomatic Milano Manual v1 PAGE 7
1. Decide where the keel cooler is going to be positioned (must be within 1.5m of the
compressor).
2. Drill a pilot hole where the keel cooler is to be located – from the inside out to avoid
hitting any stringers etc.
3. For boats with double skins, if when drilling, there is a clear gap between the inner
moulding and the hull, use a 4″ hole saw to cut away a large enough section of the inner
moulding to fit the keel cooler directly to the outer laminate. If there is no gap between the
inner moulding and the hull and the two are completely bonded together drill straight
through both laminates with a 38mm hole saw.
4. Scrape away any existing antifouling so you are back to the bare hull to bond to.
Then drill an oversized hole (40mm) so the keel cooler will easily slide up through. (it is a
good idea to do a dummy run on a piece of wood to confirm).
5. Once you have done your test, drill the hole in the hull, fit the O ring and insert the keel
cooler from the outside.
6. To hold it in place wind the nut on a couple of turns of the thread, so the washer holds it
hanging down from the hull.
7. Mask the keel cooler so just the surface to be bonded to the hull is exposed.
8. Pull the O ring up and fill the recess with your waterproof adhesive
9. Then drop the O ring onto the adhesive and add more adhesive on top of the O ring and
the rest of the top surface of the keel cooler.
10. Then with someone on the outside to hold the keel cooler in the correct orientation,
push the keel cooler up flush to the hull and tighten the nut inside.
11. Once in place just a ‘good nip’ with the spanner will hold it all in place until the
adhesive has gone off and the keel cooler will then be bonded in place.
