How to Fix / Troubleshooting

Safety first: Turn off power before tightening hardware or adjusting the unit.

Level the unit: Use a level to check the AquaCal cabinet. Shim under the base as needed to achieve level support on all corners.
Install isolation pads: Place rubber or neoprene pads under the unit feet if not already present, per AquaCal recommendations.
Tighten hardware: Check and tighten fan motor, fan guard, and compressor mounting bolts.
Add flex connections: If rigid PVC is amplifying vibration, consult your installer about adding flexible couplings on the inlet and outlet.

Heater causes excessive vibration transmitted to pad or nearby structures.
