Start-up
Chlorine concentration less than 200 ppm
1. Do not fill the water heater or operate with water
containing chlorine in excess of 200 ppm.
2. Filling with chlorinated fresh water should be acceptable
since drinking water chlorine levels are much lower.
3. Do not use the water heater to directly heat swimming pool
or spa water.
4. At initial fill and during water heater startup and testing,
check system thoroughly for any leaks. Repair all leaks
before proceeding further.
