Safety devices

■

Thermal protector — The EKHBRD indoor unit is equipped with
a thermal protector. The thermal protector is activated when the
temperature becomes too high. When activated, the protector
has to be reset on the indoor unit by pressing the red button (for
access, remove the decoration panels like indicated in the
manual of the indoor unit).

■

Pressure relief valve — A pressure relief valve (field supply) in
accordance with relevant local and national regulations, and with
an opening pressure of maximum 10 bar must be connected to
the pressure relief valve connection.

■

If a discharge pipe is connected to the pressure relief device it
must be installed in a continuously downward direction and in a
frost-free environment. It must be left open to the atmosphere.

Outlook diagram

Outlook diagram, see figure 2.

The total system (indoor unit and outdoor unit) is designed
for combination with a Daikin domestic hot water tank. In
case another tank is being used in combination with the
Daikin indoor unit, Daikin cannot guarantee neither good
operation nor reliability of the system. For those reasons
Daikin cannot give warranty of the system in such case.
