The total Daikin Altherma system is designed for
combination with a Daikin Altherma domestic hot
water tank. In case another tank or a spare part other
than native Daikin is being used in combination with
the Daikin Altherma 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.
The equipment is not intended for use in a potentially
explosive atmosphere.
For safety reasons, it is not allowed to add ethylene
glycol to the water circuit. Adding ethylene glycol
might lead to contamination of the domestic water if a
leakage would occur in the heat exchanger coil.
Only this tank can be used in combination with the
solar kit option.
Domestic water quality must be according to EN
directive 98/83 EC.
Wherever possible the main supply pipe should be in
22 mm. The minimum main water supply requirement
should be 1.5 bar working pressure and 20 litres per
minute flow rate. At these values outlet flow rates may
be poor if several outlets are used simultaneously, the
higher the available pressure and flow rate the better
the system performance will be.
It is important that the storage capacity of the
domestic water tank meets normal daily fluctuations in
consumption of hot water without any fall of the water
outlet temperature during use.
Immediately after installation, the domestic hot water
tank must be flushed with fresh water. This procedure
must be repeated at least once a day the first 5
consecutive days after installation.
If applicable legislation requires a chemical
disinfection in specific situations, involving the
Altherma domestic hot water tank, please be aware
that the domestic hot water tank is a stainless steel
cylinder containing an aluminium anode. We therefore
advise in these circumstances to use a non-chloride
based disinfectant approved for use with water
intended for human consumption.
Where the secondary return circuits are used an
additional expansion vessel may be required.
