Troubleshooting

A properly sized system should be able to supply most of your normal hot water needs during sunny times. Some of the causes of insufficient heat are listed here, but if you have checked these and are still having problems please call us at (661)-7SOLAR7 (9am to 5pm pacific) or email support@heliatos.com for tech-support.

On direct water circulation systems:

Problem	Symptom	Solution
Insufficient insuation	Fittings at the end of panel array and at bottom feed connector and in tank all at similar temperatures but water in tank does not heat up much	Install insulation on all pipes in the solar loop, no matter how warm the climate.
Air In the Loop, no circulation	Fittings at the end of panel array get very hot, but fittings at bottom feed connector don't and water in tank does not heat up	Bleed air out of loop Check if pump is running (Slight vibration and sound) Check for kinked lines or other obstructions Are all valves in the correct position
Pump not running, no circulation	Cannot feel a slight vibration when touching the pump, no slight pump sound	Check pump polarity Check wiring and connections at PV panel and pump on TD5 check selector switch setting
Pump noisy	Pump makes screeching sound and stops running	Pump noises are due to air in the pump or incorrect orientation of the pump. Make sure pump is installed horizontally and all air is bled out of the system
Bottom Feed Connector “Short Circuit”	Fittings at the end of panel array and at bottom feed connector get very hot but water in tank does not heat up	Contact us for a replacement unit
