1. CLEARFLOW PUMP
2. FLOW AND RETURN HOSE (2x 5m)
3. DUMP HOSE (8m)
4. WATER INLET HOSE (8m)
5. OVERFLOW HOSE (3m)
6. CIRCULATOR PUMP ADAPTER HOSES
7. KAMCO CHEMICAL STARTER PACK

Also included: BSP Adapters (10 pack)

1. WATER INLET VALVE (location may vary)
2. ISOLATION VALVES (2x)
3. FLOW REVERSER LEVER
4. HOLDING TANK ACCESS CAP

• Locate close to supply of mains water
• Locate close to foul water waste drain

• Connect hoses firmly by hand

• Isolate mains water supply
• Isolate cold feed
• Fit temporary cap to expansion/vent pipe

• Set thermostatic radiator valves to maximum
• Remove thermostatic valve heads
• Close by-pass
• Close auto by-pass (if present)

• Connect across flow and return pipes after boiler has been removed

• Connect to circulator pump connections using adapter hoses supplied

• Remove circulator pump head only
• Connect CP2 or circulator pump body
• Connect Clearflow Pump with hoses supplied with CP2

• Remove a section of copper pipe
• Connect with push fit connectors

• Connect Clearflow to radiator valve bodies (not suitable for microbore systems)

• Tees and valves may be fitted to boiler tails for convenient connection in the future

• Connect to pipework/isolation valves after removal of filter

• Quickly captures magnetic debris
• Speeds up flushing process
• Reduces water usage
• Customers can see what WAS in their system

• Connect CombiMAG to system using hoses and adapters supplied with CombiMAG
• CombiMAG may be connected along side Clearflow in a variety of locations

• Open water inlet valve
• Allow holding tank to fill to half way
• Close water inlet valve
• Set both isolation valves to downward “circulate” position

• System is wide open
• Activate main power switch on top of the motor housing

• Rotate flow reversal lever through 90° from left to right
• System is wide open

• Isolation valve to the opposite side of flow direction is set upwards to “dump”
• Water inlet valve is balanced to maintain water level in the holding tank

• System is wide open
• Dump to foul water waste drain (*if cylinder is present)

• System is wide open

• Ensure water inlet valve is closed
• Reset isolation valve to downward position

• KAMCO recommends Power Flush FX2
• Max power, no need to pre-treat
• Add FX2 to holding tank via access cap

• Circulate FX2 throughout system
• Turn on boiler, heat system to 50°C
• Turn off boiler
• Reverse flow regularly

• Circulate FX2 through cylinder coil only (*if cylinder is present)
• Reverse flow regularly

• Isolate cylinder
• Open radiator 1
• Circulate FX2 through radiator 1 only
• Reverse flow regularly

• Close radiator 1
• Open radiator 2
• Circulate FX2 through radiator 2 only
• Reverse flow regularly
• Repeat this process with all the remaining radiators on the system

• Isolation valve to the opposite side of flow direction is set upwards to “dump”
• Water inlet valve is balanced to maintain water level in the holding tank

• Dump radiators individually and in reverse order
• Dump until water runs clear
• Repeat step on all radiators on the system

• If no cylinder is present, go to next step

• Ensure water inlet valve is closed
• Reset isolation valve to downward position

• Open system
• Circulate neutralising crystals
• Reverse flow regularly

• Isolation valve to the opposite side of flow direction is set upwards to “dump”
• Water inlet valve is balanced to maintain water level in the holding tank

• System is wide open

• Dump until water runs clear

• When dumped water runs clear test it to be sure
• Test with Turbidity Tube and TDS Meter
• If Power Flush FX2 chemical has been used,then test with pH Paper or pH Meter as well.

• Use a turbidity tube to ensure that no particulate or solid contaminants still present
• Use a TDS meter to ensure that no soluble contaminants are still present.

• Dumped water with a pH test of 7 is neutral
• Lower pH levels will lead to corrosion in the system
• Higher pH can damage aluminium if present

• Ensure water inlet valve is closed
• Reset isolation valve to downward position

• For best results Kamco recommends using SYSTEMSAFE DM corrosion inhibitor with every power flush
• Complies with: BS7593 and Building Regulations Part L

• Add SYSTEMSAFE DM to holding tank via access cap
• Circulate SYSTEMSAFE DM
• System is wide open

• Turn Clearflow power off
• Disconnect flow and return from system
• Run flow hose to foul water drain waste
• Turn on Clearflow power, dump holding tank via flow hose to foul water waste

• Turn on boiler
• Use an Infrared Thermometer to demonstrate more even heating of radiators with cold areas removed

• Complete a Power Flushing Certificate to leave with the householder, retain the carbon copy for your records
