6.1 GENERAL NOTES

6.1.1 Components at receipt
Domestic hot water tank
?
N O T E
The unit controller (PC-ARFHE) is integrated in the DHW tank.

6.1.2 Selection of the installation location

The domestic hot water tank must be installed following these
basic requirements:
• The tank is intended to be installed in an indoor place.
• The tank is prepared to be integrated over the YUTAKI
S80 indoor unit, so make sure that selected floor is flat
and is made of a non-combustible surface, strong enough
for supporting the indoor weight and also the DHW tank's
weight completely water filled.
• The tank can be also floor mounted (Tank beside the indoor
unit both left or right sides). In this case, try to keep an
access point for the connection of the dedicated Flexible
Water Pipes Kit (ATW-FWP-02).
• Be sure to maintain the recommended servicing space for
future unit servicing (See "3.2 Service space" section).
• It is necessary to plan a fixing point between the wall and the
DHW tank.
• Take into account the space needed to install a necessary
pressure and temperature relief valve, which must be
installed at the DHW inlet connection of the tank (as close as
possible to the tank). 1 shut-off valve (field supplied) must be
also installed at the DHW outlet connection.
• Keep water draining provisions. The safety valve and the air
purge are provided with a drain pipe which are located at the
bottom side of the indoor unit.
• Protect the DHW tank unit against the entry of small animals
(like rats) which could making contact with the wires, the
drain pipe, electrical parts and may damage unprotected
parts, and at the worst, a fire will occur.
• Install it in a no-frost environment.

• To avoid fire or explosion, do not install the set in a
flammable environment.
• The tank must be installed by a service technician.
The installation must comply with local and European
regulations.
