SECTION F - TROUBLE SHOOTING, SERVICE AND REPAIR
Kamco have a "Service and Repair" facility at our premises in St Albans, and can undertake repairs or supply
replacement parts as required.
Your Scalebreaker pump was flow and pressure tested after assembly to ensure that it would perform to a high
standard. However, over time and use parts may have been physically damaged, worn out, or partially blocked by
non-soluble matter. If you are concerned that your pump may not be producing the same performance as when it left
our factory there are a number of steps that you can take to test, and repair, your unit. These are listed below. They
are not time consuming, do not require a high level of expertise and will not invalidate the warranty.
Trouble shooting / problem solving.
A flow chart is included on the following page to assist in diagnosing common problems that can be experienced on
site. The chart and illustrated test are a useful guide in determining if a problem is related to the Scalebreaker pump
or if it is a problem related to the equipment being descaled.
How to check your Scalebreaker performance.
Test 1 - Pressure test
What you need:
1. Fill the tank at least half full of full of water.
2. Point the flow reverser lever to the left.
Standard models:
3. Cap off the end of the right-hand hose.
4. Hold the left-hand hose and proceed as for point 8. below
FWF models:
5. Position the left-hand valve to "Circulate" and the right hand valve to "Dump".
6. Attach one supply/return hose to the BSP nipples (short circuiting the flow).
7. Attach the dump hose as normal.
8. Holding the end of the dump hose away from you to a suitable discharge point, switch on the motor
for five seconds. You should see a strong jet of water.
9. Attach the pressure gauge to the end of the hose end and turn the motor on for 30 seconds.
While the motor is running you should get a reading of 13psi for the C20, 23-25psi for the C40, and
26-28psi for the C90 and C210.
Test 2 - Flow rate test
What you need:
1. Repeat steps 1-7 of test above.
2. Hold the dump hose so that it will discharge water into the empty container.
3. When ready, ask an assistant to time how long it takes to fill the container.
You should get a reading of between:
7-8 seconds for the C90, 9-11 seconds for the C40, and 16-18 seconds for the C20.
4. For the CF210 fill a 25lt container which should take approximately 25 seconds.
Inspection
1. Remove the 4 bolts that hold the flange onto the tank.
2. Lift and withdraw the pump assembly from the tank.
3. Inspect the rotor cover at the bottom of the unit to ensure:
4. Inspect the inside of the impeller to make sure that there is no debris inside.
5. Check all hose connection to ensure they are secure.
If none of the above faults are apparent please call the Kamco Technical Help line on 00 44 (0)1727 875020
