20 Most Recent Pondmaster UV Clarifer Questions & Answers

According to Pondmaster, location doesn't matter as much as the flow going through it. You will have to plumb it where it is convenient for you, and allow for bypass valves. From their website:
How much water should I flow over my UV?
Just enough and not too much. Easy, right? On the contrary, this is a very tough question. To clarify, or control green water, the recommended dosage is 15 microwatts per second per cubic centimeter of water at a frequency of UVC of 265 nanometers. Whew! What this boils down to is a formula for the right amount of sunburn. You don't want to incinerate the cells, that would take too much energy, you don't even need to kill them, just to stop them from reproducing, so there is a maximum recommended flow rate that ensures that the cells passing through the light will get enough of a 'tan' to make them sterile (hence the term UV Sterilizer). Too fast a flow means not enough exposure and hence, no effect on the cells. Our UV's are rated, therefore, by the maximum flow that will still provide for enough exposure to the light to be effective. It follows that you can make a light more effective by slowing the flow, thus increasing exposure time, so we often recommend a Valved Bypass [insert link to Valved Bypass instructions] to selectively flow only part of the water going to the falls through the UV, to maximize exposure rates. However, and this is the tricky part, if the flow is too slow and not enough pondwater is being exposed quickly enough, the algae can reproduce before they make it into the UV. This sometimes happens in larger ponds with lots of nutrients and sunlight, and generally requires multiple UV units for effective control. The point is, do not exceed the maximum flow rates recommended or your UV just won't work, and decreasing the flow will typically make the UV work better.

You can tell if the UV light is on by feeling the case surrounding the light. If it's warm the light is on.
Hope that helps,

whatever the manual tells you

That is usually caused by hangups in the pull starter system creating too much friction and not transferring the pull to the motor. Here is the parts diagram and exploded view

A single pole push button would tie the fused battery feed at the ignition switch B terminal (red/white wire) to the ignition switch S terminal (orange wire).

This provides the same function as turning ignition switch to the start position with all safeties remaining functional. For engine run the ignition switch must be in run position. Push and hold push button until engine run. Turn ignition switch to off position to kill engine.

See link below for wiring diagram located in parts section of manual.

Though I have never heard of Yellowstone appliances, I am pretty sure there is a way to get replacement parts from the company spare parts department or from other sources who sell these pressure washers. If not, try the Internet, or try the Speed shops where they sell these to people who pressure wash their cars/trucks. I am also sure there are other hoses not necessarily for the Yellowstone brand but fit perfectly well on them. Find out where they sell other brands and take your washer to them, ask them if they can sell you a hose with the right connectors to fit your washer. No salesperson can refuse to sell you a good bargain.
