OPERATING INSTRUCTIONSCommercial Bubble-Up Radon Removal UnitDear Radon Professional,Congratulations on purchasing this high-quality REPCOCONDITIONER product.PRECAUTIONS:Before putting your Bubble-Up into operation, thoroughly read andfollow these instructions. This will make you familiar with theproduct and its operation. We also recommend reading the operatinginstructions for the pump, float switches and blowers.SAFETY RULES:For safety reasons, the Bubble-Up is not meant to be used by peoplewho have not previously read these instructions. This applies inparticular to children and young people under 16, who must be keptaway from the product when it is in operation.Ensure that all electrical connections are located in places that are notreachable by water.Blowers are to be mounted above the Bubble-Up.Before using the product, make sure that the main voltage correspondsto the voltage indicated on the data plate of the REPCO Control.(230 volts, single phase).(GFCI) be used in the branch circuit supplying pumps. Consult alicensed electrician or your power company if in doubt.WARNING:Operating range:ON: pressure (30 PSI)OFF: pressure (50 PSI)Specifications:Power source (Transfer Pump max. power): 16A - 230V - 60HzMax delivery (60 GPM.)Max water temperature: 35 CMax. operating pressure (110 PSI.)REPCO CONTROLS AND PROTECTION SYSTEMThe REPCO Controls convert the electric transfer pump and wellpump into an automatically operating radon removal system forcommercial use. The controls operates and performs four functions:1. It allows for transfer pump operation:It starts the tranfer pump when the pressure in the system drops to theON pressure. The transfer pump stops when the system pressurereaches the OFF pressure. The existing system pressure switch isconnected to terminals 4 & 5 in the REPCO Controls.Conformity with local and State electric codes is mandatory. TheNational Electric Code requires that a ground fault circuit interrupter2. It protects the tranfer pump from dry operation:Bubble-Up Operating InstructionsPage 1/3
The specially designed safety device automatically stops the transferpump when water is low in the 415 gallon Bubble-Up tank, thuspreventing possible damage due to the transfer pump running dry. Thestopping action is accomplished by the low water cut off float. Thisfloat closes on an empty tank stopping the transfer pump and alarmingby the red alarm light and buzzer on the REPCO Controls. Thisinforms the user of the low water condition. There are additional drycontacts, terminals 12 & 13, for remote alarm indication.3. It allows for well pump and blower operation:It starts the well pump and blowers when the level in the Bubble-Uptank drops the ON float. The well pump and blowers run and stopwhen the level in the tank reaches the OFF float.4. It protects the well pump from overflow:The specially designed safety device automatically stops the wellpump when high water is in the 415 gallon Bubble-Up tank, thuspreventing possible damage due to flooding. The stopping action isaccomplished by the high water float. This float closes on an over fulltank stopping the well pump and alarming by the red alarm light andbuzzer on the REPCO Controls. This informs the user of the highwater condition. There are additional dry contacts, terminals 10 & 11,for remote alarm indication.FUNCTIONAL PARTSl. 2 inch inlet header valve.2. 1 inch inlet supplies.3. 1st stage treatment manifold4.

Allconnecting cables, power supply and pump connections are done onthe terminal strip in the control panel.1) Connecting cables are included for the floats; connect them to theproper terminals. Connect the well pump and transfer pump to theREPCO Controls. Connect the blowers and plug them into theseparate quadplex outlet provided. Connect the system pressureswitch to the controls.2) Cut into the existing plumbing of the water system and install abypass valve set-up. Connect the inlet bypass so that the raw water ofthe existing system is going to the 2 inch inlet header valve. Connectthe outlet bypass valve back to the transfer pump discharge so that thetreated water from the Bubble-Up goes to the system.3) Connect the blowers to the inlet tee. Mount the blower above theBubble-Up. Pipe the air exhaust outside and terminate 2 feet abovethe eaves of the home and away from any windows.4) Pipe the overflow to a gravity floor drain. Do not pipe more that 10inches above the Bubble-Up or it will not drain properly and thepotential for flooding and over flow exists.PUTTING THE Bubble-Up INTO OPERATION
WARNING: BEFORE PUTTING THE SYSTEM INTOOPERATION, FILL THE BUBBLE-UP TANK AND TRANSFERPUMP WITH WATER TO PRIME. AIR MUST BE VENTEDFROM THE TRANSFER PUMP. THIS IS NECESSARY TOALLOW THE TRANSFER PUMP TO BE FILLED WITHWATER WHEN IT IS FIRST USED AND TO PREVENTDAMAGE.Place the REPCO Controls circuit breakers and HOA selector switchesin the OFF position. Power the REPCO Controls panel with a separate230 volt single phase power supply.Start the well pump by operating the HOA selector switch in theHAND position. Run the well pump and check that the operation ofthe blowers. After operation is correct place the selctor in the AUTOposition and allow the well pump to run until it shuts offautomatically.Prime the transfer pump, after it is fully primed run the transfer pumpin HAND until there is pressure in the system. Place the selector inAUTO and alloe the transfer pump to run until it stops automatically.The system is now operational. Leave the selector switches in AUTO.Never leave the selectors in HAND un-attended as the pumps will notstop automatically. The HAND position is for the trained operator totrouble shoot or test the operatiuon of the system.Draw water in the system to have the Bubble-Up cycle, check for leaksand correct operation.WARRANTYThe warranty is valid for a period of 12 months from the date ofpurchase solely for defects in materials or workmanship.

Radon from soil gas is the main cause of radon problems. Sometimes radon enters the home through well water (see page 8). In a small number

take action to reduce them. It is estimated that nearly one in 15 American homes has a radon level that should be reduced. The only way to find out about the radon level in any home is to test for it. Controlling the Risks from Radon Exposure. Testing for radon is easy. There are many kinds of low-cost, “do-it-yourself” radon test
Note: Kentucky has a state law requiring radon professionals to be certified, but as of December 2009, there were no regulations to guide the certification process. CAN RADON BE PREVENTED WHEN BUILDING A NEW HOME? Yes. Home builders can help prevent radon exposure before it starts by adding a Radon Resistant New
