I just cleaned a church yesterday 5000+ square feet.  I run 25 feet of hose.  I had to move my machine 7 times within that building to cover everything.  I have not tried running 50 feet yet.  I am also using 50 ft of 12gauge extension cord on both cords on my Ninja.  I had to reset the breakers (fuses) about 10 times.  I blow breakers in every house I go into.  Get use to it if you buy a portable.  I have bought a breaker that I plug into the wall so that I do not have to go searching for the fuse box everytime. 

 

I am doubting that with built in heat, a pump, and a couple of vacs going at the same time that one would not blow a fuse here and there (Mr. V need not chime in on this remark).  I am just struggling with it until I get the ol' truckmount.

 

However, I think one will always need a portable in his bag of tricks.

 

Cheers! 

Ken.. Whats your take on this..?

 

 

Only machines that this happens to are those that use exhaust heat as the primary heating method to heat the water.

 

 

It does not happen to direct drive units  cause they take most of their heat from liquid to Liquid exchangers. It also does not happen to Prochem 405 models like Doug uses because that system uses a water dumping system to the waste tank to moderate water temps.

 

Air cooled systems like you have rely on temperature activated selenoids and exhaust diverter valves to control excess heat when the wand is not being keyed.

Doug.. Can you explain what orifice your talking about..? This is the 2nd TM I've owned and if you set the wand down too long running all out for 10min or so and not keying the wand the watertemp gauge rises and if no water is flowing for long enough time say like 20min's it  overheats.. More in the Summer.. Doesn't do it in the Winter.. 270f shutoff safety sensor..
