NSTALLATION OF THE
HOT WATER TANK
The total AD system is designed for
combination with an AD domestic
hot water tank. In case another tank or a spare part
other than native Daikin is being used in combination
6
1x with the AD 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.
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.
