Test Run; Check Beforetest Run - Hisense AFM-54EX4SA Operation Installation Maintenance Manual

Considering measured value of water
temperature sensor differs from actual water
temperature, system will automatically correct
tested water temperature. After set as "water
temperature sensor makes invalid correction",
system will not correct tested water
temperature.
When set as "goal Pd correction 1" and "goal
Pd correction 2", the high pressure in system
will increase if heating effect is undesired, and
the heating ability will improve. When set as
"increase opening ratio of water module electric
heating", water module electric heating will shut
off when outlet temperature reaches higher
level, so that the heating ability will improve.

14. Test Run

Commissioning and test run is made as required by
table 11.2 and make record in table 11.1.

14.1 Check BeforeTest Run

Power cut before wiring. After the unit is mounted,
Check before leakage protector starts:
1. On-site wiring
The wiring between outdoor unit and water
module, water module and electronic three-way
valve, water module and domestic water tank
(optional) are made according to the wiring
diagram and national regulations.
2. Fuse or protection device
Check the dimension and type of fuse or
protection device installed on site are conforming
to technical specification in table 10.1.. Confirm
that the fuse and protection device are not
bypassed.
3. Earth wire
ensure earth wire is connected and conforming
to requirements.
4. Inner wiring
Check no loose connector or damaged electrical
component inside electrical box.
5. Fixation
Check the unit is fixed, avoiding abnormal noise
and vibration when the unit is started.
6. Damaged parts
Check no damaged component or pressed tube
inside the unit.
7. Refrigerant leakage
Check no refrigerant leakage inside unit. If
occurs, contact local dealer.
8. Power voltage
Check on-site power voltage that must be
consistent with voltage value in unit name plate.
9. Vent valve
Ensure vent valve is opened and screwed by two
circles at least.
10.Safety valve
Check system is fully injected with water. When
safety valve is manually opened, water rather
than air is drained.
11. Ball valve
Ensure ball valve is correctly installed and fully
opened. Closing valve running system will
damage water pump.
12.Electronic three-way valve
Ensure wiring method of electronic three-way
valve and installation direction of valve body are
conforming to requirements.
