In the case of the use of thermostatic valves, it is imperative not 9 0 8 to fit to all radiators, taking care to fit these valves in rooms with high input and never in rooms where the room thermostats are installed. - If it is an old installation, it is essential to rinse the radiator circuit before installing the new appliance and to add an anti- sludge filter. - If a component of the system is not to be installed immediately, protect the various connections so plaster and paint cannot compromise the seal on the subsequent connection. • Install the following components on the heating circuit return: 8 2 1 - a heating filter, - 2 quarter-turn shut-off valves (1 each side of the filter), - an air separator (if necessary), - an anti-sludge filter (if necessary). • In the case of a underfloor heating, install a security device to prevent overheating, with manual reset (55°C) on the heating circuit flow. Connect the overheating security device to the glycol pump of the heat pump. • Due to lower flow temperature of a heat pump system it is essential to flush the heating circuits with biocide to help prevent harmful bacteria building up and damaging the system.
