OK, let's start with the general set-up of the equipment and layout... The first thing we need to do is check out the areas around the perimeter of the dwelling that's going to be cleaned in order to remove all items that may get in our way during our work process as well as any items that we don't want to see get wet as a result of our actions. We should have at least 7 feet of free space to work with from the wall out to where we'll be standing most of the time as we walk from one corner of the house to the other.

I suggest starting in one corner of the house if possible, so this means we should use a hose drop to pull water from that's somewhat near that side of the house. It will also be best to have the machine centered between both corners of that side of the house so that we know that we have enough high pressure hose to make it from end to the other without any problems.

Before hooking up the 3/4 inch garden hose to our machine we should always purge that hose in order clear anything that may have got up into the male end of the hose while it was not in use. If it was outside and left open, things like lizards and small frogs may be inside it and we just can't have that going into the pump during operation. There should be a catch screen on the inlet of the pump but we will still damage the pump if that opening becomes blocked and an insufficient amount of water is flowing. So it is imperative to purge the line first. Run that hose for about 25 seconds then connect it to the inlet of the pump.

Next we hook up our 100 foot length of high pressure hose through the use of the quick connectors on the pump and hose end. Once this is done we again run the water so that it now flows through the pump and out of the high pressure hose. Run the water for 20 seconds then connect your wand to the other end of the high pressure hose.

Now since we are going to apply detergent to the walls, we will need to connect our "black soap tip" to the wand and get our mix of detergent ready in a container that we can draw from. The container should be on the ground and about 1 foot away from the machine so that the injector feed hose reaches the bottom of the container at all times.

At this point we should be set-up and ready to go.

**Make sure that the water is turned on all the way before starting the machine**

In the next module below we'll talk about the techniques used for this task.

Before you start shooting high pressure water at a house there is one important thing you should know... Please don't put your tip close to the windows when rinsing. Always keep your tip at least 4 feet back from all glass because anything closer can result in damage. If you have double-pane windows you should be back at least 5 feet and may want to consider just using the garden hose to rinse them off. They are known to sometimes get added condensation between the panes if the difference in temperatures are just right.

One more thing... that detergent we mixed up has some chlorine in it so we must ensure that any over-spray doesn't damage your plants and shrubs that may be around the house. We do this by first spraying straight clean water onto all the plant life. This is something that we have to do through-out the job, so don't forget.

OK, now that we covered all that, let's get started.

As I was saying before, we want to start at a corner of the house and do sections at a time, especially in the hot summer sun where the hot air will tend to "bake" our detergent onto the surface.

So with the machine now running and our siphoning hose in our container of detergent already we will begin to spray our mixture into the open air away from everything until you start to see a foaming substance coming out or you can smell the chlorine that is in the mix. At that point it's time to apply it onto the first section of wall. The best place to start is at the bottom corner, working your way up to the top using a back-and-forth motion from side-to-side. The wand should be directed back-and-forth at a rate in which there's plenty of solution applied to the surface. Keep doing this until you've covered a section of about 20-24 feet wide (12-16 feet if it's being done on a hot sunny day).

Once that's done, we will now be switching tips and rinsing the detergent off. You may switch the tips out without shutting the machine off as long as the trigger is not being pulled. (switch to your white 40 degree tip when rinsing)

When rinsing, start back at the end in which you started applying the soap. Instead of doing it from the bottom up, you will want to start from the top down. Use the same type of motion as before, but a little slower making sure that you rinse thoroughly and that you get any spots that may need a little extra attention. Just make sure you are no closer than 16 inches from the surface. And remember NOT to get that close to windows (4 ft. minimum distance).

Well, that's really all there is to doing a house-wash. To complete the rest of the task just follow the same instructions as above until the whole house is finished. If you get to a section that you can't reach with your wand, just take the tip off and add that extension rod to the end of the wand along with the tip you were using and you should have no problem doing the job as planned. Please Note: You will feel more backlash from the wand now that you've added more length to it, so be careful with your actions.

If you noticed a few areas need to be touched up with detergent and re-rinsed, just do it while you are in the area before you move to the next section.

When you have totally completed the task, be sure to rinse the chemical injector with clean water before storing the unit away until next time. The way this is done is the same way you pulled detergent through it. Set up a 5 gallon bucket in place of the detergent container and let the machine draw the water through the whole system until the bucket is empty. Use a minimum of 3 gallons of clean water and remember that the soap tip must be used to accomplish this.
