One of the common issues in heating systems and in the fan coil or radiator circuit is the presence of metallic deposits in the system.
The result of deposits in the fan coil circuit is the following problems:
The Dual Wash heating circuit cleaning kit is an ideal tool for a thorough cleaning of the heating circuit (radiator system):
“First, to connect the heating circuit washing kit, turn off the boiler and drain the water from the boiler and the hose connected to it, after closing the heating return valve, as shown in the image below.
Place the dual wash in the path as shown in the image.
Fill the heating circuit through the filling valve, and remove the trapped air in the filter body through the top air vent of the dual wash.
Then, turn on the boiler and set the fan temperature (for wall-mounted boilers) to the maximum possible temperature, and open all the radiator valves in the building to be in the working path.
Allow the system to operate in this state for 20 to 30 minutes.
Close the inlet and outlet valves of all the radiators from the radiator valves and allow the system to operate in this state for 5 minutes.”
At this time, we open the hot water tap in the building (for example, the hot water tap in a laundry room) and allow the system to run in this state for 5 minutes. This action is useful for cleaning metallic deposits in the secondary heat exchanger (plate) in dual heat exchanger packages, and has no effect on single heat exchanger packages. After 5 minutes, we close the hot water tap again to activate the system in the heating mode.
After cleaning the secondary heat exchanger, we open the inlet and outlet valves of the furthest radiator and vibrate the surface of the radiator with the help of a radiator vibrator (vibramax) attached to a pickaxe, according to the amount of deposits present in that radiator (at least 20 seconds).
After finishing vibrating the last radiator, we close the inlet and outlet valves of that radiator and move on to the previous radiator (the one before the last). We open the inlet and outlet valves of that radiator, vibrate the radiator as mentioned before, and then close the radiator valves. We repeat this process for each radiator one by one, vibrating the radiator and closing the radiator valve after each one. The reason for closing the radiator valve at the end of the radiator vibration is to prevent the metallic deposits freed from the system in the vibrating radiator from entering other radiators and directing them directly towards the cleaning kit. After vibrating the last radiator, we also close the last radiator and allow the system to run in this state for 5 minutes (when all radiators are closed).
After cleaning the iron rod with a cloth and closing it in place, we disconnect the cleaning kit from the system. Then, after reconnecting the primary connections to the wall-mounted fan coil unit, we flush the system and put it in a ready-to-use state.
1- It is recommended to use the cleaning kit along with injecting G3 as a cleaner to achieve the most ideal and thorough cleaning of all deposits as it results in 100% cleaning efficiency. Since it is not possible to vibrate the pipes and heat exchangers, the trapped deposits in these two parts are separated by the separating solution.
2- After cleaning the system and returning the heating system to the state of the first installation day, it is recommended to use G1 as a heating system protector solution to prevent metal and lime deposits in the heating system.
3- Installing a magnetic filter on the package devices is strongly recommended to prevent damage to the components of the wall-mounted heating package.
