A. Installation of the heat pump
The heat pump must be installed by a pool professional. End users are not qualified
to install the heat pump. Damage may occur to the heat pump or threaten the safety
of the user.
The heat pump must be installed OUTSIDE in a well ventilated area to avoid air
re-circulation, and in a place with adequate room for both installation and
maintenance. Please refer to the following illustration: The unit requires a minimum of
59.1 inch (DR-650HP, DR-900HP)/39.4 inch (DR-1100HP) of clearance from walls,
shrubbery, equipment, etc. around the entire perimeter of the heat pump. This allows
for ample air intake. Ample clearance around the air outlet is required to prevent
re-circulation of air. We recommend not placing the unit underneath eaves, decks, or
porches, as this causes re-circulation of discharged air, thereby reducing the
efficiency of the heat pump, or even stopping it
1) Be sure to fix the bracket with bolts (M10) to install the machine. The machine can
be fixed on a concrete foundation or on a bracket. The concrete foundation should
be solid and sturdy, and the bracket should be strong enough and rust-proof.
2) Don’t stack anything that will block air flow near the inlet or outlet areas, or have
any barrier within 20 inch behind the main heat pump, or the efficiency of the
heat pump will be reduced;
3) The heat pump needs a pool pump (to be supplied by user). For recommended
pump flow rates, please refer to Technical Parameter, Max. lift ≥393.7 inch;
4) When the heat pump is running, there will be condensation water discharged at

11
the base. Place the drainage nozzle into the condensation outlet and attach it
securely, then contact a drainage pipe from it to the drain.
