I am installing a split system airconditioner, is it normal for the
inside unit to have pressure in the pipes? When i went to remove the
end caps from these pipes inorder to connect the pipework from the
outside unit they are under pressure and 'gas' leaks out as soon as i
crack the nut, what is this 'gas'? is it just in there to keep the
system at a positive presure and thus prevent any moisture etc entering
the system? If not what do i do? these caps have to be removed inorder
to connect the pipes between inside and ouside units?
Thanks for any help

it will either be protective gas or it will be vacuum (less likely)

Most aircons will heat as well but from (expensive) 'lectric. A really
clever one would be a bidirectional heat pump.

It isnt a vacuum i can feel the 'gas' leaking out rather than sucking
in, what is this gas though can i just let it out and connect up the
pipework and then connect up the outdoor unit and vac pump etc.
Thanks Geoff

Yes we've got one of they in our workshop, it is "supposed" to consume
around 1Kw of power to produce 2 odd kW of heat.

Never really checked how efficient it is, as I've no means of doing so.

So, it will be summer in (hopefully) about 5 months !

Its freon gas, and without it, it will not work,

PS you need somebody to pump it back in and put under pressure, Which you cannot do yourselves

Yep, just let it out, slowly if it is on the pump side of things. It is
probably only nitrogen, so is harmless to the environment generally. Don't
leave the pipes open long. Vac ASAP

Judging by Horizon last night it could be anytime between next week and next
millenium.

The refrigerant is normally stored in the condensor part (outside
half).
