What To do
• See the Water Temperature Adjustment and Water Heater
• Wait for the water heater to recover.
• This is normal. The colder inlet water takes longer to heat.
• Consider increasing the set temperature as described in the
Water Temperature Adjustment section.
• Make sure all faucets are closed.
• Insulate piping.
• Correct piping connections.
• Check flow rate is not set too high.
• Insulate piping
• Correct installation to face south and minimize shading
• See the Water Temperature Adjustment section.
• Contact your local installer, plumbing contractor, or
previously agreed upon service agency.
• Tighten the loose connections. This should only be done by a
qualified service person.
• This is an unacceptable condition and must be corrected. See
outlet. Contact your local installer, plumbing contractor, or previously
agreed upon service agency to correct this.
Reduce system water pressure
Check all valves to ensure system can be filled with water
The combined non-return/safety valve has a check valve integrated.
If installed backwards, flow can be prevented from filling the water
heater.
