u Control Irrigation: In regions were wells are used for irrigation, water quality is sometimes less than
poor, and water spray can damage heater components. Regardless of water quality, it is
recommended that sprinklers be directed away from the heat pump.
u Prevent rain water run-off, from roofs, from pouring directly into the heater. The heater is designed
to withstand normal rainfall, but solid streams of water from roof drip-lines may eventually damage
heat pump components. If the heat pump resides beneath a roof edge, to promote heat pump
longevity, a rain leader (gutter) or rain shield will be necessary.
u Drainage: Your heat pump may produce abundant condensation under certain conditions; this is
considered normal operation. Accordingly, keep the drain holes at the base of the heat pump free
of grass, weeds, dirt, or other obstructions, allowing for free and complete drainage around the
heater.
u If the heat pump is located under trees, where leaves fall and accumulate in the bottom of the heat
pump, a qualified technician should periodically remove accumulated leaves.
Do not use a pressure cleaner to wash heat pump . . . . Damage to evaporator fins, as well as other
components, will result.
Failure to heed the following may result in damage to equipment.
CAUTION !
POSSIBLE ELECTRIC SHOCK HAZARD . . . Should you decide to wash the unit via water hose,
disconnect all power to the pool equipment pad- including, but not limited to: The heat pump, water pump,
and any and all other electrical equipment. Do NOT sprag water directly into electrical components. Do
NOT restore electrical power until such time as all water has dried completely.
Failure to heed the following may result in permanent injury or
death.
WARNING !
Maintaining Proper Water Flow
u It is important to operate and maintain the filter according to the manufacturer's specifications. As a
filter gets dirty, the water flow to the heat pump is reduced. The higher the pressure on the filter gauge,
the lower the flow rate.
u Similar to a dirty filter, large amounts of debris in the pump basket can reduce water flow. Keep
basket free of debris.
u Check for improper valve settings. A partially closed valve after the filter, or a full-open bypass around
the heater, will cause insufficient water flow through the heater.
u If the conditions listed above remain unresolved, the water flow through the heater may be reduced to a
point where internal safety devices shut the heater off. Before calling for service, always check the filter,
the pump basket, and water valve positions. If the problem persists, call AquaCal Customer Support
at: (800) 786-7751.
NOTE: During pool refinishing or acid washing, the water flow through the pool heater must be shut off
until the process is completed, and the pool chemistry is once again in balance.
