HYDRAULICS & REQUIRED FLOW RATES
This equipment must be installed and serviced by a qualified technician.
WARNING
!
Improper installation may result in property damage, serious injury or death.
Improper installation and/or operation will void the warranty.
• Water must flow from left to right (when facing the
digiHeat).
There are arrows marked on the housing to assist in
determining the correct direction.
• The digiHeat should be positioned upstream from
any chemical dosing or chlorinator and a check valve
should be installed to prevent corrosive water from
flowing back into the digiHeat.
NOTE: In the event of digiHeat being installed more than 1.8m below the pool water level
the adjustable pressure switch will not work. A flow switch (included on three phase
models) must be installed in place of the pressure switch.

REQUIRED FLOW RATES TABLE

• digiheat products require a constant water flow rate within the minimum and maximum
recommended as stated. Any filtration device and media on the hydraulic circuit with
the digiheat unit must be cleaned on a regular basis to prevent restrictions to water flow.
• Failure to observe the recommended water flow rates may void the product warranty.
• Ideally, the optimum flow rate is the midpoint between the minimum and maximum flow
rates.
