RECOMMENDATIONS
The DHw tank (secondary) must be vented and pressurised
before filling and pressurising the heating circuit (primary).
- The whole central heating system must be thoroughly flushed with clean
water before being connected to the appliance.
- The central heating safety valve is integrated and located in the appliance.
It must be connected to the drain with an air gap (allowing an inspection).
- The HeatMaster® 25 C consists of a 12 litre primary expansion cylinder.
- A de-stratification pump is built into the appliance. This pump must
operate in DHW mode as well as in heating mode. The 3-way switch must
be set to speed 3.
- Fill the system with fresh tap water. Contact your ACV representative or
installer about the use of inhibitors.
- It is possible that the connections are capped due to the presence of
residual water from tests carried out on the appliance. Please ensure
that all the caps are removed before filling the appliance.
- There is a connection and valve for filling and/or draining the appliance at
the bottom of the unit behind the front panel.
Fill the appliance to the minimum pressure of one bar. Purge the entire
installation and refill the appliance to 1.5 bar.
- Ensure that the condensate trap is fitted and connect the hose to the
drain using a connection that can be inspected. If necessary fill the trap
with clean water. Take the necessary precautions to prevent any risk of the
condensate freezing.
The connection for draining condensate must comply with
current regulations.
If there is a risk of low pressure in the hot water circuit
(installation of HeatMaster® on the roof of a building), it is
essential to install a vacuum breaker device onto the cold water
supply.
