LTCW Water Fed Pole Quiz

When using a WFP you want your TDS reading to be below...*

100ppm50ppm10ppm75ppm

Soft water and deionized water are...*

the same thingthe same in TDS but have different ppm.different and you can't use a WFP with soft water.similar in ppm

3. The first filter in a filtration system is usually...*

a mixed bed resign deionizer.a carbon filter to remove chlorine.an RO membrane filter.a sediment filter to remove physical particles.

The PSI of a filtration system matters because...*

a customer wants low PSIit can effect a proper rinse, blow out plumbing or move water too quickly through filters.you will get wet while working.it will make your O-rings dissolve.

The angle of your brush...*

can't be adjusted.doesn't matter.can be adjusted but can be risky.should be adjusted to keep brush flat on glass.

If you walk away from your pole...*

leave it descended in a safe place.leave it extended in a safe place.it doesn't matter where you leave it.leave it descended in a walkway.

The rinsing step in using a WFP is...*

not important if you follow all the scrubbing motions.critical in the final result.the first and most important step.is critical when using a rinse bar.

Water spots could mean...*

your filters could be going out or old hard water etching.you're not rinsing properly or you have the wrong rinse type.the glass needs to be squeegeed off.there's too much soap in your filters.

Drips coming down while drying could be from...*

the pole being over extended.the ppm being too high.the angle of the brush being too steep.rinsing too high on the final rinse.

You can fix scrub swirl marks by...*

rescrubbing and rinsing the glass more thoroughly with a consistent pattern.putting extra pressure on the glass with your brush.being more aggressive with your scrub.telling the boss it doesn't look good.

If a window frame is deteriorating, also know as oxidation the final result could be milky unless...*

you wipe the glass after you rinse it.you rinse first.you let the milky residue completely dry.the final rinse is below the oxidized frame.

Before you start using a WFP you should...*

remove exterior screens and shut/lock all windows.setup all the ladders you need.put towels down for drips.do the high windows first.

To avoid fatigue while using a water fed pole you should...*

not worry because it's way easier than ladder work.use your upper body the whole time.use one arm at a time.rock back and forth with your body.

If you're cleaning hydrophobic glass you should...*

go faster because you need to rinse it quickly.switch your jets to fan jets or rinse bar to disperse water or rinse sideways.clean it exactly the same as hydrophilic glass.scrub softer to avoid scratches.

When glass gets wet with WFP it looks clean so you should...*

rinse it and move on.scrub quicker before the water dries.follow a pattern to make sure everything gets cleaned.just rinse it with DI water because it already looks clean.

When setting up you should...*

pull your hose out entirely and work back to the truck/filter.yank the hose around corners if it's stuck.run the entire time for efficiency.not lock all the windows.

After you complete about five windows with the WFP you should...*

go do some windows inside to let it dry.wipe out the tracks to avoid drips.go back and look at how it's drying for quality checks.do the windows below you when drips stop.

After the high windows are done you should...*

do the low windows.do the low windows once the highs are done dripping on them.shut the water off to check for the TDS and PPM.go do the interior high windows.

Rinsing is the last step in the WFP process, you can mess this up if...*

the glass is problematicyou use a plastic coated hose in the process.you don't scrub the wall above the window.you rinse too high above the window or too far from the glass causing splatters.

If you get drips on the window as it's drying...*

you can't do anything to fix this.you probably got water too high above the frame and can re rinse lower.you should just ignore it because the customer won't notice.it's probably because you didn't scrub enough.

Partially extending parts of your WFP...*

is a bad idea because of overhead power lines.is a good idea every time you use it.is a bad idea because your WFP hose could jam up.is a good idea if you don't need the entire length to keep your pole rigid.

If you get scrub marks or brush marks on the glass...*

you need to re rinse it and it should be fine.you probably rinsed too high on the glass and need to re rinse lower.you probably didn't follow a pattern and need to re scrub and re rinse.you can assume it's normal because the window was old.

Water Fed Pole systems tend to be a lot safer for window cleaners...*

and you don't need to worry about safety.and won't cause electrocution or trip hazards.but not as good quality of service.but can still cause job hazards that should be recognized.

You should start on...*

low windows so you can watch them dry.the interiors so you can see what's dirty.the sunny side for quality of work.the high windows or windows without highs above them.

For efficiency you should extend and descend your pole...*

for each setup for best quality of work.as minimal as possible or within reason for job flow.often to ensure proper pole function and water flow.only when your ladder is broken.
