Installation Of The Rkhwe Domestic Hot Water Tank; Main Components - Rotex RKHWE300A3V3 Manual De Instalación

I
NSTALLATION OF THE
WATER TANK
The total Rotex system (indoor unit and outdoor unit)
is designed for combination with a Rotex domestic hot
water tank. In case another tank is being used in
combination with the Rotex indoor unit, Rotex cannot
guarantee neither good operation nor reliability of the
system. For those reasons Rotex cannot give
warranty of the system in such case.
The equipment is not intended for use in a potentially
explosive atmosphere.
Domestic hot water quality must be according to EN
directive 98/83 EC.
A drain device should be installed on the cold water
connection on the domestic hot water tank.
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.
It is important that the storage capacity of the
domestic hot water tank meets normal daily
fluctuations in consumption of domestic hot water
without any fall of the water outlet temperature during
use.
Take care that in the event of a leak, water cannot
cause any damage to the installation space and
surroundings.
The anode shall be inspected at least every 2 years
and, if required, replaced.
A pressure relief device of max. 10 bar should be
installed on the domestic hot water tank.
In case of limited consumption of domestic hot water, e.g. at holiday
residences or at houses that are occasionally not occupied, the
domestic hot water tank installation must be fitted with a shunt pump.
The shunt pump can be time-controlled,
the shunt pump must operate to circulate the complete volume
of the domestic hot water tank 1.5 times per hour,
and the shunt pump must operate, or be programmed for
operation, during 2 uninterrupted hours per day at least.

In case of very long field water piping between the domestic hot
water tank and the hot water end point (shower, bath, etc.) it can take
more time before the hot water from the domestic hot water tank
reaches the hot water end point.

If required connect a recirculation pump in between the hot water end
point and the recirculation hole in the domestic hot water tank.
