How to make the refer spill over fan work - 2011

We got an answer from Andrew at Swedish Marine on our spill over questions.
We have a Frigoboat keel cooler system but this would work for most spillover systems.

January 2011 - At Marina Cortez Harbor Island, San Diego, CA

"I usually put one hole up high, 1" should be sufficient. The spill over fan I mount 2 third up from the bottom. I try to mount the fan inside the separation wall so it does not protrude out, then I do a circle of 3/8" holes(maybe five) where the fan blades are. Another way would be to make the hole as big as the fan and then cover it with a closeable louver.

Here is a possible work flow for Debbie and I:

Freezer side

• Mark the spot in the freezer for the fan.
• Draw an outline of the fan over that spot.
• Drill five 3/8 holes where the blades will be.

Got to refer side.

• Put fan up against the five holes and draw an outline of the fan.
• Use a box opening knife to cut out the square.
• Now do we “paint” the inside (insulation) with epoxy and then screw in fan?
• Do we make a slightly bigger hole and fiber glass in the square then screw in the fan?
• One lawyer of fiber glass tape would work?
• If there prove to be too many 3/8 holes we could unscrew the fan and block one or more holes up.
