How to troubleshoot an FTS RS Chiller that will not start?
If your FTS Chiller unit isn't starting, it could be due to a few reasons. First, ensure that the power is properly connected; it's best to have an electrician verify the connections. Another common cause is the breaker being in the "off" position, so make sure to switch it "on". Lastly, a blown fuse could also be the culprit; a qualified person should check and replace it if necessary.
Why is my FTS RS unit not cooling properly?
If your FTS Chiller isn't cooling properly, start by checking if the temperature setting is higher than the fluid temperature and adjust it accordingly. Also, the fluid's viscosity might be too high for the intended temperature range, consider changing the fluid. The ambient temperature could also be a factor; for optimal performance, it should be around 72°F/22°C. Make sure that plumbing is correctly connected, ensuring the "LIQUID OUT" port connects to the inlet and the "LIQUID IN" connects to the outlet of the system being cooled. Check that all lines have adequate insulation, and that there are no local sources of heat that may be contributing to the load. Finally, a refrigerant leak could be the issue, in this case you should enlist a qualified, certified refrigeration technician to c...
What to do if the pump on my FTS Chiller will not start?
If the pump on your FTS Chiller isn't starting, several factors could be responsible. Begin by verifying that the power is correctly connected; it's advisable to have an electrician inspect the connections. Ensure that the breaker is in the "on" position. Another possibility is that the pump needs priming, so prime the pump. Also, the impeller might be jammed, to resolve this, verify that the motor is getting voltage and that the voltage is correct. If the fluid freezes it will jam the pump impeller. The pump motor may have overheated, it will restart when the motor has cooled down. This is usually a result of the pump being overworked. Insure that the viscosity of the fluid being used remains
How to improve inadequate fluid flow in my FTS RS Chiller?
If the fluid flow in your FTS Chiller is inadequate, it could be due to several reasons. The viscosity of the fluid might be too high for the intended temperature range, so consider changing to a fluid with lower viscosity. If you're using a high-pressure pump like the HPP2, the pump screen might be blocked, you can access it by removing the insulation from the pump and removing the large nut on the pump housing. Ensure that the ball valve is open. Check the plumbing lines for any restrictions or breaks and repair as needed. Restrictions in the system may prevent needed flow with supplied pump, so use larger line sizes or replace pump with pump capable of supplying needed flow with the given plumbing restrictions. The impeller of the pump might be damaged, remove pump and check impeller. T...
