Sentinel X300 System Cleaner is specifically designed for new central heating systems.  It flushes out flux installation debris from new indirect central heating systems. X300 cleaner helps to maintain system efficiency and conserve fuel.

• Cleans new heating systems up to 6 months old
• Powerful, heavy duty cleaning action.
• Removes installation debris, swarf, flux residues & greases
• Eliminates corrosive flux residues which could give rise to rapid pin-holing corrosion of radiators.
• Prevents harmful copper deposits being left in the system.
• An ideal preparation for X100 inhibitor.

 Packaging

• 1 litre bottle
• 10 litre cubitainer
• 20 litre cubitainer
  

• Sentinel X300 has been formulated as a cleansing aid for new central heating systems and those up to 6 months old. It will effectively remove excess flux residues, greases, oily contaminants, sludge and installation debris.
• Sentinel X300 passivates the metal surfaces in the system and helps prevent copper deposition, which frequently causes severe pin-hole corrosion in radiators.
• Sentinel X300 is a neutral formulation which can be used in all types of indirect heating systems inlcuding those containing aluminium components.
  
  

  Dosage:

  1 litre of Sentinel X300 is sufficient to treat a typical domestic system of up to 10 radiators. If the system is new, this should be at the time it is first filled. Sentinel X300 should be circulated with all valves open for a minimum period of one hour. Warming the water will aid the process.
  
  Drain and flush the system before refilling and treating with Sentinel X100 inhibitor or Sentinel X500 inhibited antifreeze.
  
  

  Feeding:

  Open Systems: Dose vis F&E cistern, via a by-pass feeder or use a Sentinel Dosing Vessel.
  
  Sealed Systems: If the system is empty, add to any convenient point before filling. If full, use a Sentinel Dosing Vessel to inject via the filling loop or other access point.

What does Sentinel X300 actually do?

Designed to clean new or almost-new systems, it dissolves or disperses the flux, greases and copper debris which are invariably left in the system after installation.

How long do I need to leave Sentinel X300 in the system?

Sentinel X300 should be circulated for at least 1 hour at operating temperature, or up to 24 hours if circulated cold... but no longer, and the system should be flushed with clean water immediately after use.

Do I need really need to flush out the Sentinel X300?

Yes it MUST to be flushed out otherwise all the contamination will remain in the system.

Is Sentinel X300 safe to use in systems that have plastic piping?

It is fine to use with plastic components. In fact, all Sentinel products have been extensively tested for use with systems having common plastic components.
