How much water should I use in my electric steriliser? We recommend using 2.7 fl oz/ 80 ml in the electric steriliser. To make it super easy to remember we have marked 80ml on the bottle with a small dotted line so no matter how little sleep you get you will always remember!
Remove all items from inside the steriliser base. Pour exactly 80ml of water into the steriliser base.
Autoclaves are large water consumers. Without a water miser, an autoclave can consume 45-50 gallons of water per minute, 24 hours a day, 7 days a week.
The heat absorbed is calculated by using the specific heat of water and the equation ΔH=cp×m×ΔT. 4. Water is vaporized to steam at 100oC. The heat absorbed is calculated by multiplying the moles of water by the molar heat of vaporization.
All you need to do is pour 80ml of water into the base of the unit. The unit then heats the water turning it into steam which then sterilises the products.
Use distilled water in your sterilizer.

Any other type of water, such as tap, bottled, and even filtered, may contain deposits in it that can build up around the heating element and result in a shorter product life.

You can leave sterilised items in the steriliser or pan until you need them but the majority of manufacturers advise using or re-sterilising after 24 hours. If you do take sterilised items out, you`ll need to put the teats and lids on the bottles immediately.
Do you need to dry sterilised baby bottles? No. Any remaining water inside the baby bottles will be sterile. Using a towel, no matter how clean it seems, to dry baby bottles runs the risk of introducing bacteria back inside baby`s bottles.
Cold water sterilising solution

Change the sterilising solution every 24 hours. Make sure there are no air bubbles trapped in the bottles or teats when putting them in the sterilising solution. Your steriliser should have a floating cover or a plunger to keep all the equipment under the solution.

With the chamber door OPEN, turn the multivalve clockwise from “0“ to “FILL WATER”. chamber. Once the pressure gauge reaches “ZERO”, open the chamber door and use the drain valve and drain hose to drain ALL of the water out of the water reservoir into a pail. TURN THE AUTOCLAVE OFF AND ALLOW THE CHAMBER TO COOL.
All you need to do is pour 80ml of water into the base of the unit. The unit then heats the water turning it into steam which then sterilises the products.
Water is poured into the sterilizer and microwaved for several minutes. This method usually takes less time than an electric steamer. If you cannot boil, steam, use a dishwasher or don`t have clean water, the CDC condones the use of bleach to clean baby bottles.

Need instructions how to use Hoover Steam Vac Spin Scrub. I borrowed it from my Sister and she left it with no instruction book or letting me know how to operate it. I put water & cleaner in top tank. That’s all I know to do. Do I put any water in bottom tank? I figured not, since that is probably where the water goes when sucked up by vac. Do I leave lid on bottom tank? I usually use a commercial cleaner, and this is very different. I need to know NOW, as I must return it to her today, and I’m
ANSWER : I did have a solution in just a few minutes. Someone responded with a solution that gave me the website where I could go and print the manual in pdf, so did that, and checking instructions I was able to clean my carpets and get the shampooer back to my sister later the same day. I really appreciated your site and help I got for my problem. I found it on google. Thanks again!

We lost our instructions to the Kirby Shampoo attachement and how to attach it to the main unit, the belt and how to use it. We need complete instructions and explanations on how to use this as we have tried and the belt does not attach to the main unit, the brush does not turn and the hops along the carpet and no water, etc. returns to the tray.
Please help us with as simple and complete instructions as possible.
ANSWER : First, you’ll need to fill the tank with water (warm or cold). There are three fill lines on the side of the tank. Fill to the desired line and add one shampooer tank lid full of Kirby shampoo for each line of water. A full tank will require three lids full of shampoo.
Remove the outer cloth bag by rotating the bottom boot AWAY from the side of the main unit. Put the tank where the bag was, line up the notch (or may be a small arrow) on the tank with the notch on the Kirby near the hole. Set the tank down onto the Kirby and rotate it toward the Kirby to lock it on.
To remove the Kirby power nozzle, go to the front of the machine and turn the belt lifter clockwise until the red arrows line up. Turn the latch at the top to release the nozzle and take it off.
Make sure that the GREEN arrows on the hood’s belt lifter are lined up. Put the shampooer hood onto the tray, covering the shampooer brush and splash guard. The belt lifter should be FACING the hole in the center of the tray. While looking into the large hole in the rear of the shampooer hood, turn the belt lifter slowly and “hook” the belt with the belt lifter. Continue to turn it until the RED arrows on the top or the belt lifter line up. This stretches the belt to it’s highest position, preparing it for attachment to the main unit. This action also binds the hood to the tray. It may be a bit hard to turn, as the belt may be stiff if the shampooer isn’t used often.
Attach the shampooer assembly to the Kirby in the same manner as the power nozzle. (Put the little hooks on the hood onto the outside edges of the bar in the front, push it toward the Kirby and lock it on)
Now, turn the arrows back to green matching green. This will position your belt onto the drive shaft and make the nozzle ready to shampoo.
Lower the front of the Kirby to it’s lowest setting. You may raise it up one click if you have thick carpeting. Either one is fine.
Now, all that’s left to do is attach the tank to the tray using the hose. One end goes on the tank shampoo outlet which is located near the on off valve. The other end “pops” into the hole in the center of the tray.
Turn the Kirby on, turn the foam setting to “on” and lay the foam out onto the carpet by pushing FORWARD QUICKLY and BACKWARD SLOWLY. The foam is ONLY being laid out onto the carpet when the machine is going BACKWARD and wastes into the front tray when going forward, so going forward quickly uses less shampoo for the same job. The quantity of foam being deposited to the carpet is controlled by the speed of the backward movement. The slower you go, the thicker the foam.
Lay the foam out in strips, overlapping the edges a bit for good coverage. For tough stains, try going over the area in two different directions when laying the foam in that area. Don’t go over an area too many times though…it will get too wet and can cause a thick build-up of carpet protecter and soap. Pick up the foam by turning the shampoo valve back to “off”. Simply run the shampooer slowly and smoothly over the foam and it will pick it up and deposit it into the tray in the front.
Once you get the feel for the foam laying process, you should be able to do a whole room without emptying the tray. Make sure that you transition from forward to backward slowly and smoothly, especially as the tray fills up with dirty water. Jerky movements will cause the funk to slosh back out onto the clean rug.
PERSONAL ADVICE>>> I like to lay the foam in 3′ to 4′ square blocks and then pick it back up before moving on to the next area. This prevents the foam from being spread over too large an area. If it takes you too long to pick the foam up, it may dry out a bit and won’t do as good a job as when it’s fresh and damp.
Now that you’ve gotten this far, I imagine that you’re enough of a veteran to detach the shampooer and reassemble the vacuum. My advice in this area is for the shampooer cleaning process. Make sure that you release the belt from the hook by turning the belt lifter to GREEN before trying to seperate the hood from the tray. If you don’t do this, you’ll never get them apart.
If this guide was helpful to you,Thank you!

Turbine Hi I found out through your site that my turbin is bad on my steam vac and I found some information as well on how to disasemble the steam vac to get to the turbine but still was wondering if there were some more detailed instructions on how to remove the turbin. I am a sigle mom and doing the work on the steam vac myself and need a little more detailed instructions. Please help asap and have a bless day.
ANSWER : There are some screws on the bottom that have to come out so you can remove the top housing. Take the brush block out, there are 2 screws above where it sits. The turbine sits near the front, and in the mid section, 2 screws on the front of it and 2 long screws from underneath, if you already haven’t removed them. Unhook the hoses to it thenpick it out and replace with the new one. ( Some models near the back of the housing, is a catch on each side that you have to unhook to release the top).

While using my mop yesterday, it stopped letting steam come out. Tonight I plugged it up again and you could hear it trying to steam. I push the button in to release the square frame and it pushed out a burst of steam and pushed the head off. Put it back together and it still will not let steam out. No matter how much water is in it.

I do not have my users manual and have never vacuumed wet with this vacuum. How do I change it from a dry to wet vacuum.
Can’t find my manual and I need to use the shop vac for water in basement, do I have to change the filter or what
lost my user manual never used it to pick up water. need to know how to puit it in wet mode i want to clean the dirty water out of my pool.
ANSWER : .Vacuuming Liquids
.1. When picking up small amounts of liquid
.the filter may be left in place.
.2. When picking up large amounts of liquid
.we recommend that the filter be
.removed. If the filter is not removed, it
.will become saturated and misting
.may appear in the exhaust.
.3. After using the vac to pick up liquids,
.the filter must be dried to reduce the
.risk of possible mildew and damage to
.the filter.
.4. When the liquid in the drum reaches a
.predetermined level, the float mechanism
.will rise automatically to cut off
.airflow. When this happens, turn off
.the vac, unplug the power cord, and
.empty the drum. You will know that the
.float has risen because vac airflow
.ceases and the motor noise will
.become higher in pitch, due to
.increased motor speed.
.IMPORTANT: To reduce the risk of damage
.to the vac do not run motor with float
.in raised position

I have a bissell quickwash 1950-e. I bought it Jan. 2006, and have only used it 8-10 times, I live in a very hard water area, so I though if I put some vinegar in with the cleaning solution it would get rid of any hard water deposits, unfortunatly the solution went lumpy in the tank and stoped spraying out water, I have opened it, hose clean, sprayer not blocked, x at bottom of water container when depresed water trickles out, component that opens the x when water container placed, also ran wate
ANSWER : Hard to say what is causing your problem, replacing the cap and insert on the water tank may help, part #2041111, even tho it may trickle out water when depressed, they can still be bad. The other thing would be the rod not relesing the water like it should. The big draw back to this model is Bissell has obsoleted all of its parts and most are no longer available. Might be wiser to buy new.
