CHAPTER 8
QUICK CONNECTS
All the components of the Frigomatic unit are supplied with Frigoboat quick connects which
retain the refrigeration gas that has been factory pre charged and permit quick and simple
connection of the refrigeration system.
IMPORTANT
Under no circumstances run the Frigomatic compressor unless the two quick
connects are fully joined.
8.1 COUPLING THE QUICK CONNECTS
The quick connects on the condensing unit are fitted with plastic dust caps. Do not
remove these until the last minute when you are ready to connect the system together.
The Quick Connects seal with O rings, so they do not rely on compression and it should be
possible to do the couplings up by hand without the need for spanners (subject to access).
Centre the two halves precisely, align the quick connects so the nut (D) can be screwed by
hand into the male half coupling (IM).
Do not let the male end of the quick connect turn.
It is important to fully make the couplings so the two nuts are touching to ensure the quick
connect is fully open. Use a spanner just to nip the nuts in place and prevent them coming
loose.
If after the coupling has been pushed together you get a continuous hiss take the
couplings apart at once as it is possible that the 'O Ring' (G) has been damaged. Spare 'O
Rings' are provided (bag taped to top of compressor).
Take care not to bend or twist the two pipes during the above operation and always use
two wrenches of the correct size to nip the couplings in place. Having completed the first
coupling you can then proceed with the second one but more care is required when
connecting the red and yellow labelled high pressure pipes because the smaller tubes
terminating in a male coupling will not tolerate abuse.
Remember again that a leak proof joint is not dependent on the tightness of the nut but
that is important that the nut is screwed up to the full depth of the thread.
