14 FASTER POWER FLUSHING
- Quickly captures magnetic debris
- Speeds up flushing process
- Reduces water usage
- Customers can see what WAS in their system
Kamco CombiMAG
15 CONNECTING CombiMAG
- Connect CombiMAG to system using
hoses and adapters supplied
with CombiMAG - CombiMAG may be connected along side Clearflow in a variety of locations
16 PREPARE CLEARFLOW PUMP
- Open water inlet valve
- Allow holding tank to fill to half way
- Close water inlet valve
- Set both isolation valves to downward "circulate" position
17 POWER FLUSHING BEGINS
- System is wide open
- Activate main power switch on top of the motor housing
18 REVERSE DIRECTION OF FLOW
- Rotate flow reversal lever through 90°
from left to right - System is wide open.
19 SET VALVES TO DUMP
- 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
20 DUMP RADIATORS & CYLINDER*
- System is wide open
- Dump to foul water waste drain *If cylinder is present
21 DUMP UNTIL WATER CLEARS
- System is wide open
22 SET VALVES TO CIRCULATE
- Ensure water inlet valve is closed
- Reset isolation valve to downward position
23 ADD POWER FLUSH FX2
- KAMCO recommends Power Flush FX2
- Max power, no need to pre-treat
- Add FX2 to holding tank via access cap
24 CIRCULATE FX2
- Circulate FX2 throughout system
- Turn on boiler, heat system to 50°C
- Turn off boiler
- Reverse flow regularly
25 ISOLATE RADIATORS
- Circulate FX2 through cylinder coil only*
- Reverse flow regularly *if cylinder is present
26 OPEN RADIATOR 1
- Isolate cylinder
- Open radiator 1
- Circulate FX2 through radiator 1 only
- Reverse flow regularly
27 OPEN RADIATOR 2
- 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
28 SET VALVES TO DUMP
- 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
29 DUMP RADIATORS
- Dump radiators individually and in reverse order
- Dump until water runs clear
- Repeat step on all radiators on the system
30 DUMP CYLINDER
- If no cylinder is present, go to next step
31 SET VALVES TO CIRCULATE
- Ensure water inlet valve is closed
- Reset isolation valve to downward position
32 ADD NEUTRALISING CRYSTALS
- Open system
- Circulate neutralising crystals
- Reverse flow regularly
33 SET VALVES TO DUMP
- 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
34 DUMP NEUTRALISED WATER
- System is wide open
35 DUMP SYSTEM
- Dump until water runs clear
36 TEST DUMP WATER
- 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.
37 TEST FOR CONTAMINANTS
- 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.
38 GET TO pH7 NEUTRAL
- 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
39 SET VALVES TO CIRCULATE
- Ensure water inlet valve is closed
- Reset isolation valve to downward position
40 SYSTEMSAFE DM
- For best results Kamco recommends using SYSTEMSAFE DM corrosion inhibitor with every power flush
- Complies with: BS7593 and
Building Regulations Part L
41 CIRCULATE SYSTEMSAFE DM
- Add SYSTEMSAFE DM to holding tank
via access cap - Circulate SYSTEMSAFE DM
- System is wide open
42 DISCONNECT AND DUMP
- 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
43 RADIATOR HEAT DISTRIBUTION
- Turn on boiler
- Use an Infrared Thermometer to demonstrate
more even heating of radiators with cold areas removed
44 LEAVE A RECORD
- Complete a Power Flushing Certificate to leave with the householder, retain the carbon copy for your records
