Plumbing connection installation guide
2. Placing the unit and water connections
a. Placing the unit and fixing
• The frame must be fixed by bolts (M10) to a concrete foundation or brackets. The concrete
foundation must be solid and fastened; the bracket must be strong enough and anti-rust treated.
• Do not stack substances that will block air flow near the inlet or outlet area, and there should be
no obstruction within 50cm behind the machine. Suffocation of air reduces the efficiency of the
heater and could damage the unit.
• The machine may need an additional pump (not supplied). The recommended pump must
adhere to the specification-flux of the machine, please refer to the technical parameters.
b. Water connections
• The inlet and outlet water unions should not be installed with soft flexible pipes. The heat pump
must be connected with rigid pipes!
