13. Check water circuit before test run
(A) Confirm all water pipes are constructed in
correct state before test run.
(B) Inject water into water module. Confirm
circulating water is fully injected into plate heat
exchanger. Open water pump and vent valve to
confirm air is discharged from the unit and
pipeline.
(C)Switch DSW3-2(details are seen below) to
ON position to forcibly operate water pump.
Check water pump is correctly mounted by
reading pressure gage and confirming water
switch action. After check, reset DSW3-2,
otherwise, water pump will keep running.
(D) After first test run, clean water filter and confirm
no dirt in filter net.
● The unit starts only when all check points are
cleared up.
● Pay attention when system is running:
(A) Do not touch any part in exhaust end, because
the housing of exhaust end in compressor and
pipeline has more than 90ºC temperature.
(B) Do not press AC contactor button, otherwise
serious accident may be caused.
● Do not touch any electrical component 3
minutes after main power supply is cut off.
14.2 Energize Water Module
After water module is energized, wired controller
icon will be shown in initial state, which lasts 10
seconds. Displaying contents refer to the
Fig.3.1 "wired remote controller".
● It is normal that after water module is energized,
it may directly enter anti-freezing running mode,
and water pump automatically runs if outdoor
temperature is very low.
14.3 On-site Setting
●
Installation person can set up selected
parameters based on installation environment
and user’s needs. Details refer to the section
5.1.7 in part I.
14.4 Test Run and Final Check
After installation finishes, the installation person
must check water module and outdoor unit are
correctly installed.

Test run of floor heating
Test run of floor heating is made according to
the section 5.1.3.3. After test lasts 2 hours or it
reaches set temperature, system will
automatically stop. Also it may be stopped by
pressing ON/OFF key. If there is error or
failure, the wired controller screen will show
error code. Error code refers to the table 14.2.
●
Test run of domestic hot water
Test run of domestic hot water is made according
to the section 5.1.3.4. In general, when water
temperature increase by 5 ºC, the water tank
heating will work normally.
When test run of floor heating is made, higher
temperature in water module (55 ºC) will damage
floors due to expansion and contraction.
Recommend it is within 30 minutes.
