Step 4: If there is any pressure drop in 30 minutes, or if any leakage is found, identify and fix the leakage. Then
conducts the full leak test again until there is no leakage and pressure remains constant in 30 minutes.
Note
The pressure for the leak test must not be over 10bar in both Thermopod panel and pipe connection.
Caution
Warranty requirement that the Nitrogen pressure test and vacuum processing test must be evidenced with a picture,
to show the pressure level injected or the vacuum level respectively.
Vacuum Processing
This is a critical process for the system to be completely vacuum before loading the refrigerant fluid. The purpose of
this process is to remove all the air and moisture inside the pipe work and Thermopod panel. If the system is not
completely vacuum, the system will be soon deteriorated.
Step 1: Start vacuum process by using a vacuum pump.
Step 2: Hold the system in vacuum for at least 30 minutes or less than 20pa shown by vacuum manometer.
Step 3: Make sure no change in the vacuum manometer for 15 minutes after stopping the vacuum pump.
Step 4: After the vacuum process, the two valves shall be opened for the refrigerant to circulate.
Note
If the system deterioration caused by a failure of this vacuum process, it is not included in the warranty period.
Thread sealant is recommended for all existing thread connections.
Caution
For vented system, please adjust the water pump mode from default I / S1 to III / S3. This action can enhance the
internal pressure to draw air inside the water pipe.
Standard for vacuum completion: After 10 minutes of system operation, No Unusual Sound from Compressor, and
difference of two temperatures on the screen not more than 5 degrees.
Additional Refrigerant Charge
The Thermopod is pre-charged with 1400g of refrigerant R134a, sufficient enough for up to 10M of physical
separation pipe length between Thermopod and Thermopod panel.
The pipe-run length can be extended up to 15 meters of physical separation between Thermopod and Thermopod
panel. 20g of refrigerant R134a shall be added for every extra 1 meter length of pipe.
It is important for connections between
Thermopod and Thermopod panel to have as
less bends as possible, in which the load loss
shall be minimized. Check the additional
refrigerant charge accordingly.
