Installation and maintenance manual

5 Decommissioning

WARNING!

Danger of scalding and flooding when opening the

solar return flow coupling or heating and hot water

pipes due to escaping hot water.

● Only drain the storage tank container or heating

system

– when they have been left to cool sufficiently,

– with a suitable device for the safe draining or

catching

of escaping water,

– wearing appropriate protective clothing.

5.1 Temporary shutdown

CAUTION!

A heating system which is shut down can freeze in the

event of frost and may suffer damage.

● If there is any risk of frost, drain any water from the

decommissioned heating system.

● If

the heating system is not drained and there is a

risk of frost, the power supplies must be secured

and the external main switch must remain switched

on.

If the Daikin Altherma EHS(X/H) is not required for a long time, it

n be temporarily decommissioned.

Daikin therefore recommends that you do not disconnect the

system from power supply, but rather only place it in "Stand-By

Mode" (consult the operating manual for the control system).

The system is then protected from frost. The pumps and valve

protection functions are active.

If it is not possible to guarantee the power supply when there is

danger of frost,

– completely discharge the Daikin

Altherma EHS(X/H) on the

water side, or

– suitable antifreeze measures must be

taken for the connected

heating system and hot water storage tank (e.g. draining).

If there is a danger of frost and the power supply cannot

be guaranteed for just a few days, the unit's excellent

heat insulation means that the Daikin Altherma

EHS(X/H) does not have to be drained, provided that

the storage tank temperature is monitored regularly and

does not fall below +3 °C.

However, this does not provide frost protection for the

connected heat dis

tribution system.

5.1.1 Draining the storage tank

● Disconnect the Daikin Altherma EHS(X/H) from the power

supply.

● C

onnect the outlet hose to the KFE filling connection

(accessory KFE BA) (fig. 5-1, item A) and run to a drainage

point that is at least soil deep.

If no KFE filling connection is available, the con-

nection piece (fig. 5-1, item C) can alternatively be

removed from the safety overflow (fig. 5-1, item B)

and used.

Once the drainage process is complete, this must

be replaced before

the heating system can be

started again.

from the storage tank con-

tainer.
