I bought a used bottle warmer and it didnt come with instructions. So all I have is the warmer with 2 wires sticking out of it. So how do I hook this thing up?

Thanks, Justin

 

One wire each on a double A!

I'm sure there is a how-to page somewhere around here...

 

Well, it's supposed to come with either bottle pressure sending unit or a thermostat.
Is it a NOS system?

I hooked mine up to 2 pincer clips and I plug it to batery +,-
The only thing is I have to monitor the bottle pressure carefully so it doesn't overheat. It's no problem for me as I only use N2O with a warmer at the track, so I get the pressure up, unhook the heater, do a run and voila.

 

So I guess I just need one to be a ground and one to a 12V source, then put a switch in the middle?

 

Basicaly yes, but like I said you have to have a thermostat on the bottle otherwise you will overheat and the safety valve on the bottle will rupture and empty the contents. I hooked mine up to a cigarette lighter plug because I only heat the bottle in the pits. I get 1000-1050 psi and the I hit the track that gives me 100 psi cooling margin and I'm still in the 5177 uptimum range of 950 PSI.

 

What I'm saying is if you hook the warmer without monitoring device, ie: directly to +,- source you cannot do that unless your next to the pressure guage to monitor pressure. In my case the guage is on the bottle in the boot so I can only do that in the pits with the trunk open.

 

you need 2 things, 1 is a relay, as the heaters can draw up to 30 amps, too much for most switches.

you need some 10 gauge wire running to the back.

and second, you need a control device, if you don't have one, you can skip it.... but you better keep a close eye on the temperature.

for the wiring, the relay will have 4 wires. 85 86 87 30

30 goes to battery, fused.
87 goes to one wire on the heater pad
85 goes to control device, then that to ground
and 86 connects to your switch, which provides +12 when the switch is on.

Ground the other end of the heater pad, and your set.

i agree with SLOW on the 30 amps thing, I cured that by using the alternate plug (SIDE) in my Z which I hooked to a 35 amp fused source. Most of the time I hook to my Bros. Truck battery with pincer clamps.

 

Cool thanks guys, I have it hooked up and working now but how hot is it suposed to get? It gets pretty warm in the middle but the edges dont heat up any. Is this normal?

 

Heat transfers to liquid N2O in contact with bottle. Just monitor pressure. 1100 MAX. You'll be fine. Mine does the same.
