INSTALLATION
HEATING CONNECTION
The HeatMaster
®
has two connections at the rear that can be used
to connect a central heating circuit. Connecting a heating system
may reduce the domestic hot water performance.
Expansion
The HeatMaster
®
200 models are equipped with 4 8-litre expansion
vessels. These expansion vessels are sized for hot water operation
only. If a heating system is connected to the primary circuit, calculate
the expansion capacity necessary for the total volume of the heating
system.
(Refer to the technical instructions from a relevant manufacturer of
expansion vessels)
.
Example of a single circuit connection
1. 4-way valve
2. Heating pump
3. Non-return valve
4. Isolating valves
5. Safety valve set to 3 bar with pressure gauge
6. Expansion vessel
7. Drain cock
8. Controller
(optional)
9. Surface-mounted sensor
(optional)
WARNING
The pimary safety valve is supplied with a plastic tube
connected to the discharge outlet - this is for test
purposes only and should be removed. The safety
valve should be connected to a drain using a metallic
pipe eg. copper.
BEWARE
In the case of heating at low temperature, the use of
the kit
(code: 10800099)
