How to change psi settings on 1003hv

I bought a used mytee 1003 hv carpet extractor. I keep reading reviews about it. Anyways the review says is can go to 500 psi. Right now it is at 200 psi.

So do they make a model without out the dial? It doesn't have one on the front.
The model does say 1003 hv speedster.

Try this:

Pick up the phone and call 858.679.1191
That is Mytee, they built the unit, they can tell you how it works
Go right to the horse's mouth

The dial is definitely on the 1003DX, the 1003HV is its predecessor
Feel free to ask Mytee
Let us know what you learn from Mytee

Weird... Yeah I'll have to call. It does have two vac buttons on the top and the bottom has heater and pump. It has the psi gauge with the circuit indicater light. No knob on it. On the front it has a 1003 picture. On the back by the model it say 1003 hv. There is no black nob or any proof that there was one on it. I'll call em later tonight. Thank you

Alright she called me back saying I have an older modell which was made in 2000. It's an older pump set at 200 psi. She said u can increase it but there really not a way other getting into everything. It's a pump there no longer using. It's odd that it's a 1003hv... Works great tho. Thank you all for the help. A little bum I don't have the knob for differnt psi but 200 psi works.
