FibroPool FH135 Installation And User Instructions Manual page 7

Please install the drain adapters beneath the heater prior to installation.. You can attach 5/8" hose
to the adapters to direct the condensation water.
· On a typical installation on a pool with a small pump, such as ½, ¾ hp pump with 1 1/2"
PVC or flexible hoses, only the plumbing IN from the BOTTOM and OUT from the TOP pipe
connection is necessary.
· For stronger systems (those with 1.5 HP and larger pumps and 2 inch plumbing systems) a
bypass system should be installed.
· ** A BYPASS SYSTEM IS NOT NECESSARY FOR ABOVE GROUND POOLS****
· If the heat pump is connected to a filtration circuit with a by-pass valve: We suggest to open
the bypass 50% then adjust down to achieve the lowest flow rate into the heater without
triggering error messages (EE-3, PL, EE1). This will give enough water to the heater without
restricting the flow. The IN and OUT difference should be 1-5° Fahrenheit. If the difference
is too great, increase the water flow through the heater for optimal heating.
· The old system BYPASS path usually consists of 3 valves. The New FIBROPOOL BYPASS
VALVE is just 1 valve. This makes it possible to adjust water flow passing through the heat
pump.
