12. HYDRAULIC LINKS
When choosing and installing water pipes, you must consult and observe all current local standards,
regulations and instructions.
12.1. GENERAL RECOMMENDATIONS
You must design the pipe network with the minimum number of bends and keep the number of changes in
height to the strict minimum. This will reduce installation costs and ensure optimum system performance.
The pipe network must include:
²
A vibration elimination system (e.g.: link hoses available as an accessory) on all pipes connected to
the appliance in order to reduce vibrations and noise transmitted to the building fabric.
²
Stop cocks to isolate the hydraulic circuit during maintenance.
²
Manual or automatic bleed valves at the highest point on the water circuit.
²
A suitable system for maintaining water pressure in the circuit (expansion tank).
²
The installation of thermometers and pressure gauges on the heat exchanger inlet and outlet to
facilitate day-to-day controls and system maintenance.
12.1.1. ANTI-CLOGGING PROTECTION
When installing Aqu@ Scop HT appliances in existing water circuits,
a sludge trap and a removable mesh filter should be installed
upstream of the appliance.
To avoid any risk of foreign bodies entering the appliance and
to guarantee operating performance, WE STRONGLY RECOMMEND
THAT YOU INSTALL THE WATER FILTER ACCESSORY on the
Aqu@ Scop HT inlet pipe.
To ensure that the system operates correctly you must use suitably sized and properly routed pipes for the
hydraulic links between the Heat pump and the mains network.
The volume of water contained in the installation must be sufficient to avoid any possibility of the compressor
"short cycling", and to guarantee adequate compressor running times in order to provide optimum service
life and to ensure that de-icing cycles are performed properly.To ensure the Aqu@ Scop HT functions
efficiently, available installation water volume must be:
12.1.2. MINIMUM HEATED WATER VOLUME REQUIREMENTS – BUFFER TANK.
200l < available water volume < 250l
When water circulation through heat emitters can be interrupted (thermostatic radiator valves closed) or the
heating supply halted, you must ensure that:
²
The heat pump maintains its nominal water flow,
²
The heat pump operates in a loop with a minimum available volume of 200 litres.
The use of a 3-speed circulation pump enables water flow through the appliance to be adapted to pressure
losses in the system. (Pump supplied set on Max position).
