INSTALLATION INSTRUCTIONS FOR KLEER REMEDIAL SUPPORT PASSIVE SKIMMERS RSS25L/50L/75L MEMBRANE FILTERS
- read prior to installation-
METHOD OF OPERATION
Remedial support skimmers remove gasoline and diesel from water using a filter membrane located under the slotted filter chamber near the top of your skimmer. Our three standard skimmers are designed to float, when empty, with a part of the filter chamber at the fluid surface. As the skimmer fills it will sink lower. You should limit the distance the skimmer can sink by setting the cable length to a distance demanded by your current fuel and water levels. If the fluid elevation changes, simply adjust the cable so that some of the slots in the chamber contact gasoline/diesel.
To operate most efficiently the fuel/water interface should be at the lower end of the slotted filter to allow as much hydrocarbon as possible to cover the slotted section. The filter is designed to recover a fuel layer of any thickness floating on water when it touches the slotted filter. The KLEER ® reservoir is always below the fluid surface; ensure that you have sufficient depth of total fluids to accommodate the length of your reservoir.
We have developed your skimmer, often called a passive bailer, downhole oil/water separator or fuel recovery bailer, through two decades of field use. If you have site challenges, call us any time.
ATTACH permanently your cable or custom length stainless chain to the wellhead to ensure that you will not lose your KLEER ® downhole! DO THIS FIRST! An eyebolt is included for this attachment.
Your standard passive KLEER ® Remedial Support Skimmers (RSS25L, 50L, 75L) will float prior to recovering hydrocarbon fluid. Skimmers sink as they fill; cable length must be set according to the current interface depth in order to limit the descent of the slotted filter chamber downward into the water table. The highest point on your skimmer that the interface can be skimmed is near the top of the slotted filter chamber, approximately 0.35 metre [13-14"] below the top of the 1" diameter vent tube on standard length passive KLEER ® skimmers.
It is important that you know the depth [DEPTH] below wellhead of your stabilized fluid surface. Subtract 0.35 metre from that depth; make this CABLE LENGTH, the length of your cable & eyebolt above the vent tube. Remember to include the length of eyebolts, hooks, etc at the wellhead which are part of CABLE LENGTH.
** CABLE LENGTH (above vent) = DEPTH minus 0.35m **
Adjust the cable length by simply loosening the two securing nuts on the clamp, sliding the cable-end loop up or down and re-attaching it with the clamp on to the cable.
Ensure the drain valve at base of skimmer is closed. After filling with fuel lift your skimmer and empty it through the drain valve or the vent tube. The standard valve on RSS75L (4") skimmers opens when the handle is pushed sideways in the receiving vessel by the weight of the skimmer.
To dissipate any static electricity, ground your skimmer using a jumper wire between the brass valve and your container or ensure the base is in contact with your container before emptying.
If you cover the filter in mud, it may need to be hose-rinsed from the outside with fresh, room temperature WATER only. Avoid detergents, alcohol, waxes, solvents, surfactant or water jets.
There is no need to open the slotted filter cartridge; there are no serviceable parts. Opening the slotted section may damage the filter assembly.
Q:My skimmer does not collect any fuel, why?
A:Cable too short or too long. Recalculate distance for CABLE LENGTH and re-install your skimmer. If this doesn't help, there is no more gasoline/diesel downhole!
Q:My skimmer fills up only partially with fuel while water table is static, why?
A:Cable too long. If your KLEER ® skimmer only partially fills, and hydrocarbon fluid remains in the well, the maximum cable length should be shortened. Excessive cable length may also allow water into your skimmer through the top! (feel free to extend the 1" o.d. vent tube)
Q:What maintenance do you recommend?
A:BEST MAINTENANCE IS NO MAINTENANCE (of course, keep it clean, and do not break it or loose it!). If your fluid has suspended solids and trash; if the well diameter allows, wrap any polypropylene "oil-only" mat around the slotted filter, securing with string or copper wire etc.. Unwrap and replace if it becomes clogged.
Water can not harm your skimmer, but avoid the damaging debris of well floods.
Q:What about warranty?
A:Your skimmer filter is guaranteed for two years to repel water and collect gasoline & diesel. If you have any problems, just phone us.
