Installation Of The Indoor Unit; Selecting An Installation Location; Dimensions And Service Space - EAS ELECTRIC ETHKH160 Manual De Instrucciones

NOTE
In normal condition, port A should be opened, while signal sent to
the 3-way valve (29), port A will be closed and port B will be
opened. When in cool mode, ON signal will sent from outdoor unit
to the 3-way valve (29), the cold water will flow through port inlet to
port B, and port B should connect to the fan coil units. While in
heating mode, the hot water will flow through port inlet to port A,
and port A should connect to the floor heating loops. In this way, all
the water from the unit will flow through the floor heating loops and
thus ensure better performance of the floor heating.
As the temperature sensor is used to detect the room temperature,
the user interface(3) should be placed in the room where floor
heating loops and fan coil units is installed. Correct configuration
should be applied in the user interface (refer to " Field settings/
TEMP. TYPE SETTING" ). The target room temperature can
be set on the main page of user interface, the target outlet water
temperature will be calculated from climate related curves, the unit
will turn off when the room temperature reaches the target
temperature.

5. INSTALLATION OF THE INDOOR UNIT

CAUTION
The indoor unit should be installed in a water proof place, or the
safety of the unit and the operator cannot be ensured.

5.1 Selecting an installation location

The indoor unit is to be wall mounted in an indoor location
that meets the following requirements:
The installation location is frost-free.
The space around the unit is adequate for serving, see figure
5-3.
The space around the unit allows for sufficient air circula-
tion.
There is a provision for condensate drain and pressure relief
valve blow-off.
CAUTION
When the unit running in the cooling mode, Condensate may drop
from the water inlet and water outlet pipes. Please make sure the
dropping condensate will not result in damage of your furniture and
other devices.
The installation surface is a flat and vertical non-combustible
wall, capable of supporting the operation weight of the unit.
There is no danger of fire due to leakage of inflammable gas.
All piping lengths and distance have been taken into consid-
eration.
Table 5-1
Requirement
Maximum allowable piping length between the
3-way valve SV1 and the indoor unit (only for
installations with domestic hot water tank)
Maximum allowable piping length between the
domestic hot water tank and the indoor unit
(only for installations with domestic hot water tank).
The temperature sensor cable supplied with the
indoor unit is 10 m in length.
Maximum allowable piping length between the T1B
and the indoor unit. The temperature sensor a
cable of T1B supplied with the indoor unit is 10m in
length.
The equipment is not intended for use in a potentially explo-
sive atmosphere.
If the installation is equipped with a domestic hot water tank
(optional), please refer to the domestic hot water installation
manual.
