1.4.d In-Line Chlorine Feeders
Place in-line chlorinators downstream from the heat pump and as low in elevation as possible.

If an erosion type feeder is used, it is recommended that a Hartford Loop be installed to protect internal heat
pump components.
l
A Hartford Loop is not necessary with a Salt Chlorine Generator.

1.4.e Water Flow Rates
Maintain water flow rates as indicated. Please note, these specifications relate to the heat pump only. Code-
specified whole system turnover rates must be satisfied.
NOTICE
Failure to heed the following may result in damage to equipment.
l
Water flow exceeding maximum flow rates will negatively affect the total pool filtration performance and may
damage the heat pump. This will not be covered under the equipment warranty.
