REFRIGERATION SERVICE
General Information:
Work on the refrigeration system should only be done when it is certain that the system needs repair.
Refrain from checking refrigeration |
|
| |
pressures without reason. Visual inspection |
|
| |
of the water system, observation of the ice |
|
| |
formation, amp draw, voltage, and other |
|
| |
techniques will lead to proper diagnosis. |
|
| |
Scotsman also recommends that, at the time of |
|
| |
initial start up, gauges not be used. |
|
| |
If gauges must be used, don’t always check the |
|
| |
high side pressure. If the condenser is clean and |
| ||
seems to be operating correctly, it most likely is. |
| ||
The low side pressure is more important on an |
|
| |
ice machine than the high side. |
| Allen | |
If gauges must be used, use very short hoses to | |||
Wrench | |||
minimize refrigerant discharged into the air. |
|
| |
Refrigerant should not be added except as a |
|
| |
way to determine the proper operation of the |
|
| |
product. If the system was low on refrigerant, |
|
| |
there is a leak, and it must be found and |
| Torque Stem to | |
repaired. |
| ||
This system has a critical charge, it must be | Torque Stem Cap to | ||
recharged with the correct amount of refrigerant | |||
as listed on the nameplate of the ice machine, or |
| ||
performance will suffer. |
|
|
Anytime the refrigeration system has been opened, the dryer should be replaced. Note:
Only a HFC type dryer should be used.
When brazing the tubing connections to components such as the TXV, the component must be protected by heat sink material.
