The SYSTEMSURE IK6 injector enables corrosion inhibitors, flushing chemicals and boiler noise suppressants to be injected directly into the main flow of heating systems.
It is used to inject liquid chemicals through the air bleed screw of just one radiator, with no need to drain off any water or even to locate the feed and expansion tank.
With no need to enter the loft space, the whole process can be carried out in less than five minutes.
The SYSTEMSURE IK6 injector is equally as effective when injecting chemicals into sealed systems, removing the need to re-pressurise a system after injection of chemicals.
It is supplied complete with two special nickel plated steel air bleed valve adapters for the most common radiator bleed valve sizes.
An additional adapter allows connection to the filling loop on combination boilers.
The IK6 has a 4 litre capacity tank, enabling it to be used to add chemicals to even the largest domestic systems with one operation. 6 & 8 litre capacity Systemsure units can also be supplied to special order.
APPLICATION & USAGE:
The Systemsure IK6 may also be used for spray application of chemicals. It is constructed of thermoplastic materials suited for use with a wide range of industrial chemicals, including acids, and may be used for cleaning, disinfecting and degreasing.
The IK6 sprayer/injector includes an adjustable nozzle, a spray lance incorporating easy action on / off valve and integral filter. The see-through tank has a visible filling level scale, an external safety valve with red over-pressure indicator, and clip for the lance.
To inject chemicals into central heating systems through the radiator air bleed valve:
Ensure that the heating system is switched off, and that the circulator pump is not still running. Assemble the IK6 unit with the two supplied flexible hoses connected at each end of the combined handle and on/off valve.
Unscrew the pump unit from the top of the tank, add to the tank the liquid to be injected, and screw the pump unit firmly back onto the tank.
Select the Systemsure air bleed screw adapter suited to the radiator into which chemical is to be injected.
Close both radiator valves on the selected radiator. Unscrew the air bleed nipple, taking care to catch any liquid with an absorbent cloth. Screw in the chosen air bleed screw adapter, using PTFE tape if necessary to obtain seal. Fasten the end of the flexible tube onto the adapter, and reopen the radiator valves.
Pressurise the unit by pumping the handle twenty times. When the red indicator on the safety valve appears, stop pumping. Air will be expelled through the valve and no more pressure will be raised within the tank.
Squeeze the metal handle on the injector lance and hold until contents of tank have been injected into radiator. Release handle and pull out external safety valve until pressurised air in IK6 is released. Again close radiator valves. Unscrew air bleed screw adapter, replace radiator bleed screw and reopen radiator valves.
The normal circulation of the heating system will now distribute the chemical throughout the system.
As a means to clear an individual radiator blocked with sludge or corrosion debris:
Assemble the IK6 as previously, and select the air bleed screw adapter suited to the radiator.
Close both valves on the radiator. Unscrew the radiator air bleed nipple, taking care to catch any liquid with an absorbent cloth. Screw in the air bleed screw adapter, using PTFE tape if necessary to obtain seal. Fasten the end of the flexible tube onto the adapter, and pressurise the IK6 by pumping the handle twenty times. When the red indicator on the safety valve appears, stop pumping.
Squeeze the metal handle on the injector lance in order to pressurise the radiator, and then open ONE radiator valve only. Wait for two minutes, close the open radiator valve, and pump the IK6 twenty times to restore pressure.
Squeeze the metal handle on the IK6 injector to re-pressurise the radiator, open the other radiator valve and wait for two minutes. Open both radiator valves and put the full flow of a power flushing pump on that radiator alone, by shutting off all other radiators. There should now be water flow to that radiator.
As a spray applicator for cleaning, degreasing, and descaling chemicals:
Assemble the IK6 with one flexible hose running from the connector near the base of the unit to the combined handle and on/off valve. Screw the rigid spray lance, with appropriate spray nozzle, on the other end.
Unscrew the pump unit from the top of the tank, and fill the tank to the required level with the liquid to be sprayed. Screw pump unit firmly back onto the tank.
To spray, squeeze the metal handle on the spray lance, and adjust the nozzle to obtain the desired spray. Pressure, and therefore spray intensity, drop with use. Pump more to regain pressure.
Maintenance:
Most frequent malfunctions and their solutions:
1. Avoid seals becoming dry by washing the unit after use.
2. If the spray nozzle becomes obstructed, clean with water jet or non-metallic probe.
3. If the filter becomes blocked, remove it from the handle and clean.
