3. Heating commissioning
3.1 Commissioning flowchart
3.2 Indoor and outdoor unit running checking (refer to cooling
1.if any leakage on
one-way valve of
slave unit
2.if the expansion
valve is closed
completely after
slave unit is turned
off
3.if there is leakage
on solenoid valve
4.if there is
refrigerant leakage
on system, if
additional refrigerant
charging is standard
heating debugging is finished
system running confirmation, if the slave unit start
up frequently
problem is resoved, system running confirmation,
debugging in heating mode is finished
ystem runs stably, (accumulative total running at least an hour),
record the running data, see attached table 6
， data analyse see
attaced table 7
After troubleshooting, set indoor at heating mode
analyse the running data, see attached table 7
System runs stably, (accumulative total running at
least an hour), record the running data, see attached
table 6
For the first time being electrified, each slave
unit will run into oil equalization mode after it
accumulative total running for 30 minutes
To find out the reason according of
the failure code, resolve the problem
all outdoor unit start to run and four-way valve
change directions, master unit highest frequency
during the first 15 minutes of being electrified
for the first time is 60 HZ
check if there is any fault on
indoor unit
confirm outdoor unit
confirm indoor unit
system confirmation
if the master unit can not find all the indoor units, it can not start to run,
electrify outdoor unit 12 hours in advance before trial operation, set
temperature at 16
℃, when debugging in heating mode, outside environment
temperature should lower than 21
℃, all indoor units run in heating mode
and at high speed, set temp. at 30
℃（ start up the unit totally in heating
mode compulsorily. SW3/SW4/SW5 is 15/1/0
， press SW2<press SW1 to
cancel> for 5 seconds
