  Cooling system faults. 

  How to diagnose faults: 

It should take approximate 3 hours to reach the lowest setting temperature of 5

  for an empty  unit (assuming ambient 

temp of 32 degrees centigrade and continuous operation). If not, check the compressor, cooling fans, controller, and sensors. 

If all these are working normally, there is probably a cooling system

s fault.

 

 

  How to repair the defualt

 

1. Check the compressor 

Turn on the unit and check there is electricity current flowing to the compressor using a caliper type Amp meter, the 

current should be within 0.6 to  2 Amps.  If the readings are not in this range, turn off  and cut off the pipes 

(See Fig.8 

showing  G)

 and the seal pliers

 (See  Fig.8 showing E.) 

from the  compressor, then turn the  unit  on again (

in  this  case 

only  run  the  compressor  for  a  few  minuets,  so  as  to  avoid  the  compressor  absorb  moist  air

)  and  recheck  the 

current  and  if  there  is  pressure  at  the  outlet  pipe.  If  the  current  reading  is  still  out  of  range  specified  above  and  no 

pressure from the compressor outlet, replace the whole compressor. 

 

2.

 Check the cooling system pipe work: 

Carefully  check  the  cooling  system  after  verifying  the  compressor  is  working  normally.  Then  follow  the  procedure 

below. 

1>.

  Then  cut  off  process  pipe  and  check  the  refrigerant.  If  there  is  not  enough  refrigerant,  the  defualt  of  the  refrigerant 

system should be caused by the leaking. If the refrigerant is sufficient., it is probably jamed in the capillary.   

 

2>.If the default is concentrated on the cooling system, the checking procedure is as below. 

A. Cut off the vent pipe of the compressor, and infuse 0.8-1MP nitrogen by 

process pipe

, and please put the hand close 

to the cut kerf of the vent pipe. If there is a little gas leak form the terminal, it means normal, or it is jamed. 

B. Make sure the  capilary is working normally,  when  the drainpipe is connetced again, and infuse  0.8-1MP nitrogen 

then  test  the  leakage  if  the  cooling  system  of  the  soldering  point  with  the  soap  water.  Check  from  the  the  soldering 

point arround the compressor

(Fig.8 & Fig.9

Fig.9.1)

, and if everything is ok, remove the air-duct board and chech 

the soldering point around evaporator

(Fig.6 & Fig.7)

. please see the remove method and the procedure as below

.

 

(Fig.1, Fig.2 ,Fig.3,Fig.4 & Fig.5)

 

C. If all the soldering point in B is not leaking, there are two possibility, one is leakage in the inner condenser, another 

is the damage on the parts

such as evaporator,condenser and so on

  in the cooling system. If it is the inner damage, 

it can not be repaired, and if the damage on the parts, replace them. 

3>. Make sure that there is not leakage in the cooling system, refill the refrigerant. 

 

3. Refill the refrigerant: 

1>. Using the vacuum pump form a vacuum in the system, via the joint of the low-pressure process pipe on the compressor , 

the high-pressure pipeline is  on the process pipe of the filter. Apply the vacuum pump for approximately 20 minutes. Until 

the  vacuum  is  lower  than  100Pa.  Then  solder  the  compressor  process  pipe  of  the  filter.  Keep  the  vacuum  running  while 

soldering this joint 

2>.

Fill  Cooling  system  with  refrigerant  via  the  process  pipe.  (The  refrigerant  is  R134a.  Regarding  refrigerant  quantity 

Please  refer  to  the  instruction  at  back  label  of  wine  cellar).  Then  solder  the  compressor  process  pipe  after  the  system  is 

charged with refrigerant. 

 

4. Running test: 

 

Replace  all  the  components  after  the  procedures  above  and  turn  the  unit  on.  To  verify  the  effectiveness  of  the  repair, 

monitor
