Level Loc Plug and Play Auto Top Off Product Description

Level-Loc is a self-contained auto top off unit for replacing evaporated water in any aquarium or tank that has a sump. 

The Bracket

The PVC bracket allows you the ability to mount the unit on the side of almost any glass aquarium sump or plastic storage tub.  Two nylon thumb screws secure the bracket to the sump wall.  A large 1 7/8" suction cup on the inside of the sump, further stabilizes the unit.  The float is mounted on a sliding tube that allows you to raise or lower the float to the desired water level.  The tube is secured in place by a short nylon thumb screw.

Shown here, is a Level-Loc mounted on a 75 gallon aquarium.  The riser tube is raised to the uppermost position.  The bracket can accommodate rims up to 1.5" wide.

  The Float Valve

  The float valve controls the flow of water into the sump.  It is made of
  polypropylene with a stainless steel locking bolt and wing nut.  We ship an
  optional nylon bolt and nut with each unit in case you are uncomfortable
  using stainless steel in your aquarium.  I prefer the stainless steel since it is
  stronger and doesn't noticeably corrode in contact with saltwater.  Either
  option works just fine.  The float can be swiveled to point in different
  directions to allow for obstructions in your sump.  By loosening the wing
  nut, the float can be adjusted up or down depending on your needs.  The
  water line connects to the float with a compression nut.  The unit comes
  fully assembled out of the box.








The Solenoid and Float Switch

The purpose of the solenoid and float switch combination is to provide safety backup to the float valve.  In the event of a float valve failure (mechanical, stray power cord, snail, etc.) the float switch will sense the rising water and the solenoid will close.  In the picture above, you can see the float switch is mounted just slightly above the float valve.  Having a solenoid also gives you the added option of plugging it into a timer so that the water is only on when the timer turns on the solenoid.  This gives you an added layer of safety and allows your RO/DI unit to run less frequently and generate more water at one time, extending the life of the RO membrane.

The solenoid is 12V DC which makes it safe around water and energy efficient.  It is constructed from polypropylene and stainless steel so no corrosive materials come in contact with the fresh water.  The wire connectors on the solenoid are completely insulated with heat-shrink connectors to ensure that the terminals do not corrode.  The wiring connections to the float switch are inside the riser tube which is sealed with 100% aquarium safe silicone.



Kalkwasser (lime water)

The solenoid produces temperatures approaching 140 degrees Fahrenheit.  Due to these high temperatures, dosing kalkwasser through Level-Loc will cause precipitation inside the solenoid which will eventually obstruct water flow.  Additionally, kalkwasser particles can obstruct the solenoid and float valve.  Therefore, using kalkwasser voids our warranty.  If you choose to do this, please clean the solenoid often by running RO/DI or vinegar through the unit periodically (do not allow vinegar to enter your aquarium).

The supply water is connected to the solenoid via a push-connect fitting (shown in the picture above).  No tools or extra fittings are required.

The optional timers are Intermatic brand appliance timers.  We normally ship these preprogrammed to turn on 4 times a day.  The timers are completely digital, have battery backup and automatic adjustment for daylight savings time.
