Why is the MTA Chiller water temperature too high?
- J
  johnsonwilliamAug 15, 2025
  The water temperature in your MTA Chiller might be higher than expected due to several reasons: the thermal load could be too high (restore it to the preset limits), the ambient temperature could be too high (restore it to the preset limits), the condenser fins may be dirty (clean them), the front surface of the condenser could be obstructed (free it), or there might not be enough refrigerant fluid in the plant (in this case, get a technician to check for and eliminate leaks, then refill the plant).

What causes the compressor protection to trip on my MTA Chiller?
- A
  Alexis PhillipsAug 22, 2025
  The compressor protection on your MTA Chiller might trip due to: a thermal load that is too high in conjunction with a high ambient temperature (stop the machine and restore the load within the preset limits, then wait a few minutes before restarting), a thermal load that is too high along with a lack of refrigerant in the circuit (get a technician to check for and eliminate leaks, then have the engineer refill the circuit), or the same issues that cause the high pressure switch to trip.

What to do if my MTA TAEevo M05 Chiller is obstructed and the water isn't flowing?
- A
  Andrew HawkinsAug 26, 2025
  If your MTA Chiller is obstructed and the water isn't flowing, it could be because the set point is too low, causing the water to freeze (raise the set point or add an appropriate percentage of ethylene glycol (antifreeze)), or the evaporator is obstructed by dirt carried by the water to be cooled (clean the evaporator by running a detergent solution which is not aggressive for steel, aluminium and copper, or run a high water flow against the stream and install a filter upstream from the chiller).

Why does the FC1 fuse trip on my MTA TAEevo M05 Chiller?
- D
  Dr. Amy LutzAug 28, 2025
  The FC1 fuse in your MTA Chiller might be tripping because of compressor motor overloading or a short circuit, or a short circuit in the compressor power line. To resolve this, use a tester to check the motor windings and the power cable. Replace the compressor or cable if necessary, and then change the fuse.

Why is the FF1 fuse tripping in my MTA TAEevo M05?
- N
  Nathan FreemanSep 1, 2025
  The FF1 fuse in your MTA Chiller may be tripping due to fan, pumps, and electronic power overload, or a short circuit in the power line. Check the components and wiring with a tester, replace any damaged components or wiring, and then change the fuse.

Why is the water pressure low at the pump outlet of my MTA TAEevo M05?
- M
  michelle95Sep 4, 2025
  Low water pressure at the pump outlet of your MTA Chiller could be due to excessive clearance between the impeller and the pump casing, indicating worn parts. You should verify and replace the pump impeller.

How to fix a faulty -BT1 probe on my MTA TAEevo M05?
- R
  Reginald HernandezSep 7, 2025
  A faulty -BT1 probe on your MTA Chiller, or parameters out of range, can be resolved by checking or renewing the probe.

What to do if MTA Chiller continues to operate with old values after parameter modification?
- M
  Mr. Brian Rodriguez MDSep 12, 2025
  If your MTA Chiller continues to operate with the old values after modifying a parameter, it may be because the instrument has not updated the old value or the parameter programming procedure was not concluded correctly. Turn the instrument off and on again or re-program the parameters correctly.

What to do if the high pressure switch (HP) trips on my MTA TAEevo M05 Chiller?
- T
  Thomas PerezNov 18, 2025
  If the high pressure switch (HP) trips on your MTA Chiller, it could be due to several reasons: the fan may not be working (repair or replace it, and check the thermal protection switch if fitted, then press the reset button on the cap of the pressure switch), the ambient air temperature may be too high (reduce ambient temperature within design limits by increasing local ventilation, then press the reset button on the cap of the pressure switch), there could be recirculation of warm air due to incorrect installation location (change the position of the unit or any adjacent obstructions to avoid recirculation, then press the reset button on the cap of the pressure switch), the condenser fins may be dirty (clean the condenser fins, then press the reset button on the cap of the pressure switc...
