Installation, Use and Maintenance
CAUTION:
When choosing the size of the pipes, make sure that the maximum pressure
drop of the system as stated in the technical data in paragraph 2.4.1 is not
exceeded (see useful head).
Always connect the pipes to the connections using the wrench-to-wrench
system.
Make a suitable drain for the safety valve.
It is the installer’s responsibility to check that the expansion vessel is suitable
for the actual capacity of the system.
3.6.2.
General
The hydraulic connections must comply with the national or local regulations; the
pipes may be made or steel or galvanised steel. Flexible hoses may be used if their
diameter is larger. The dimensions of the pipes must be chosen carefully to suit the
nominal water flow rate of the appliance and the pressure drops in the hydraulic circuit.
All of the hydraulic connections must be insulated with closed-cell insulation of adequate
thickness. The refrigeration unit must be connected to the pipes using new flexible
hoses that have not been re-used. We recommend fitting the following components in
the hydraulic circuit:
• Thermometer with sensor for the reading the temperature in the circuit.
• Manual valves to isolate the unit from the hydraulic circuit.
• Y-shaped metal filter and filter-settler (installed on the system return pipe) with a
metal mesh not larger than 1mm.
• Loading unit and discharge valve if required
3.6. Hydraulic connections
3.6.1. The accessories to be connected to the AHP60 hydraulic station
-The hydraulic connections must comply with good engineering practices according to the
regulations in force.
-Before making the hydraulic connections, the supply pipes must be cleaned to avoid contami-
nating the tank with metal or other types of particles.
-The Plumbing British standards.
-Check when hot that the pressure does not exceed the service pressure.

Recommendations
: for regions where the water is hard, the use of a water softener does not
imply any change in our Guarantee, provided that the softener is adjusted in line with trade
standards, and is checked and maintained regularly.
-
The hardness of the water must remain above 10°f.
