Electric pipe freezer operation question

[Ookysoft]

I have acquired a FreezeMaster FRE350D pipe freezer.

Firstly, should the fan run as soon as it's switched on or does it wait until it gets warm - If the latter, is that likely to be more than 10 minutes.

Secondly, is it typical for 1 of the freeze heads to freeze much faster than the other?

Lastly, any economical source for replacement clamps - or do most folks just jury-rig something?

fan runs straight away.
both my heads freeze equal.

i would say it needs re-filling.

Ditto, fan runs straight away and heads should freeze equally. The clamps are nothing special, buy some normal G-clamps from any DIY shed

Thanks guys! I kinda assumed the fan should run straight off... seems pointless not to draw air though the radiator fins. I can fix that - not looking forward to a refill cost for the gas though....... If car refills are any thing to go by! D'oh!

Check what type of refridgerant it uses - cars use R123a.

If it uses the same, you can go to Halfords and buy a can of top-up for about 15 quid.

its not the same as cars a lot use Refrigerant R-404A
