5.2 Outdoor Unit Draining Operation
YUTAKI M / YUTAKI Hydrosplit has no drain port factory supplied. It is highly recommended to
install a drain port valve attached to the water outlet of the YUTAKI M / YUTAKI Hydrosplit unit in
order to ease the operation of draining. When the drain port is installed the draining procedure
for the YUTAKI M / YUTAKI Hydrosplit follows the next steps:
1 Switch OFF the main power of the unit.
2
Close the shut-off valve installed at the water inlet connection (field supplied).
3
Connect a pipe or a drain hose to the drain port (field supplied) placed in the water outlet
pipe of the unit.
4
Open manually the drain port of the shut-off valve (field supplied), and collect the water into a
bucket (or to a sewage system)
5
Once all the water has been drained, and all maintenance operations have been finished,
close again the drain port and open again the valve of the water inlet pipe to restart the
normal operation of the unit.
5.3 Indoor Unit Draining Operation
5.3.1 Draining operation for YUTAKI H
YUTAKI H models have no drain port factory supplied. It must be considered the installation of a
drain port after the shut-off valve (factory supplied) and before the water inlet of the unit when
proceeding to the installation of the unit.
