Dhw Pipes Connection; To Insulate The Water Piping - Hisense Hi-Therma-Serie Bedienungsanleitung

PIPING WORK

8.3.3 DHW pipes connection

● The connection between the DHW installation and
the DHW connections of the indoor unit must be done
taking into account the following considerations:
(1) Install a pressure relief valve ( factory supplied) at the
DHW inlet connection (as close as possible to the DHW
tank) to provide the following functions.
● Pressure protection
● Non-return function
● Shut-down valve
● Filling
● Draining
If not, a specific device for each function should be installed.
(2) Install also a shut-off valve (field supplied) in the
DHW outlet connection, in order to make easier any
maintenance work.
For more details, refer to the section "9.1 ADDITIONAL HYDRAULIC
NECESSARY ELEMENTS".

8.3.4 To insulate the water piping

● The piping in the complete water circuit MUST be
insulated to prevent condensation during cooling
operation and reduction of the heating and cooling
capacity.
● If the temperature is higher than 30°C and the humidity
is higher than RH 80%, the thickness of the insulation
materials should be at least 20 mm to prevent
condensation on the surface of the insulation.
