2.1 Water Chemistry
Check water chemistry regularly and maintain within recommended levels. Standards vary in different
residential and commercial applications. Follow all local applicable codes.
NOTICE
Do not allow water to flow through the heat pump when refinishing or acid washing a pool. Use an installed
l
bypass to route water away from the heat pump or deactivate the filter pump.
To avoid damage to equipment, monitor and maintain chemistry within recommended levels.
