O ring installation guide

Transcription

1 AtomicRice.com O ring installation guide Tools and materials needed: 1) Phillips Screwdriver ( one medium and one large head) 2) Small or Medium sized flathead screwdriver or thin rigid shim 3) Vaseline or any type of Non toxic lubricant (Water or Oil based is okay). Installation: 1. Unplug all electrical connections from filter canister. 2. Remove Pump head unit from filter canister main body. 3. Using a Phillips screwdriver, unscrew the two (2) screws located on top of the pump head next to the intake and exhaust ports. 4. Turn over the pump head unit and underneath you should see 4 small screws on each corner of the pump head. Remove these screws and put the screws in a safe location. When done, turn over the pump head. 5. Carefully remove the pump head top cover. 6. Using the flathead screwdriver, carefully pry off the grey top cover plate of the priming button. The priming button top cover plate has the logo Eheim Professional written on it. There should be a couple small slits along the outside perimeter of the cover plate that you can carefully wedge the head of your flathead screwdriver into to pry off the plate. 7. Once you have removed the priming button cover plate, you should see three (3) small silver screws. One of the silver screws might have a plastic or some type of glue on top of it. This I believe is used to indicate if any tampering has been done to the motor unit. Using a Phillips screwdriver carefully unscrew these screws. Caution: The screws are holding down the plastic priming button housing which sits under spring tension. Please be careful and unscrew the screws a little at a time going from one screw to the next to keep the tension balanced. 8. Behind the priming button cover is the actual motor of the filter. The motor is sealed unit which cannot be opened. The motor is also part of the priming unit which is what some call the push button primer.

2 9. Take out the springs inside each corner post and put it away someplace. Carefully and slowly push the priming unit down until the unit emerges from below. You will see the o ring (orange color?) surrounding the priming unit. 10. At this point you may take out the o ring and clean the entire priming unit with water to rid of detritus and other gunk that has accumulated there. 11. Once cleaned, take your brand new AtomicRice.com o ring and liberally coat the entire o ring with Vaseline or some other lubricant. Make sure you don t use a toxic lubricant that can harm your fish. Vaseline and its generic brands work pretty well and are very cheap. Don t worry about the petroleum in the Vaseline harming your new o ring. The o ring you bought from AtomicRIce.com is custom formulated and made to withstand petroleum based oils and most other rubber eating chemicals. One word of caution, don t mix Vaseline type lubricants with silicone spray lubricants because they tend to mix together and dissolve their lubricating abilities. 12. Once you have lubed the o ring, rub a little bit of lubricant into the slot the o ring is going to occupy. 13. Next you may want to take some of your lubricant and rub it around inside the well walls that the priming unit goes up and down along. This will help you slide the priming unit easier back into position and into the shaft. 14. When pushing the priming unit back into the shaft, you will notice that the priming unit will get stuck midway down the shaft. Unfortunately because of the way the filter is designed, the tolerance in space calls it to be very watertight. In this case, you will need to push a bit hard to slide the rest of the way through. CAUTION: don t push too hard otherwise you will cause the o ring to get pinched. Try this method; push the priming unit hard enough that you still have control of its descent. When you have passed the stoppage area, you will see that the o ring may have bulged out a little bit. 15. If you see that the o ring has bulged out a bit or a lot, get a flat head screwdriver and with the flat side of the screwdriver, try to push the bulged out area back into the groove. This might take a few tries. If you still can t get the bulged area back in, you may want to pull the priming unit back out and start over by pushing it back in, but this time give it a few small twists (left, right) while pushing down to get the o ring settled in place. Continue pushing the priming unit in and if it helps, use a flathead screw driver to help guide the o ring past the pinching area (where the valve meets the motor s valve). If you don t see the o ring being pinched, you should be okay. 16. Finally, you are done installing the o ring. Now just put all the pieces back together starting with the springs and the priming unit cover. Again, make sure you put even pressure on the cap when screwing it back down. Before putting the pump head cover back on, test the push button priming unit by pushing the priming unit down and letting the springs bring it back up. You should feel the ease of its slide down and up. You should not encounter much of any resistance other than the force of the springs pushing back at you. If you feel the movement getting stuck along the way or the springs not pushing back instantly, you may have not put enough lubricant. If you try to push the priming unit down and you have a hard time doing it. The o ring may be pinched, if this happens, you need to take the unit apart again and lubricate better and try to guide the o ring in and make sure you don t see any part of the o ring being pinched near the

3 valve area. Just remember, don t force anything, if you feel a lot of resistance, something is wrong. If you keep fighting it, you will ultimately damage the o ring by pinching it and cutting the material. 17. When everything is put back, put the filter through back inline and test the priming function. Again, this action should be smooth with no resistance other than from the springs. Once the filter is primed, turn on the filter and observe the filter to see if any leaks occur. To be safe, I would check up on it every 15 minutes and then go up to 30 minutes and then check once every hour for at least 4 6 hours. Why so long? You want the filter to be rid of all the trapped air inside the canister. If you look at the water flow gauge you will see that the flow of water is either very low or medium, this is because of the air that s still inside the canister. By giving the filter 4 6 hours, you are letting it get rid of the air naturally. By the time the filter is ready, water flow should be greatly increased and water flow should be at its max. After 6 hours, you should be safe to assume that the o ring is doing its job of keeping the filter air and water tight. Congratulations, you have just successfully installed the AtomicRice.com o ring into your Eheim filter. With proper maintenance (lubricating it periodically) your o ring will last many years.
