• Unit subjects to floor installation must be placed on a concrete slab. The slab must have thickness of 100mm and 50mm
wider and longer than the footprint of the unit (Figure 5). Place the concrete slab a distant from building to prevent
vibration and noise.
• In the case of heatpump operation with an outdoor temperature below 0°C, the unit must be installed at least 300mm above
ground level. This is necessary to prevent ice from accumulating on the frame and to permit proper operation in the event
of heavy snowfalls.
• The unit must be leveled on both axes. (Tolerance is less than 2mm per meter.)

Note: For cooling nominal values are based on 12°C / 7°C entering / leaving evaporator water temperature, 35°C air ambient temperature.
• All water pipe must be adequately insulated to prevent capacity losses and condensation.
• Install a 40 to 60-mesh strainer to ensure good water quality.
• Water pipes recommended are black steel pipe and copper pipe.
• During installation, the piping of the unit should be clamped before rotating the installation pipe to reduce the moment
induce on the piping.
• Users are recommended to install the pipes and accessories as shown in Figure 7.
• An air vent must be installed at the highest position, while a drainage plug at the lowest position of the water circuit. After
the leak test (0.6MPa), open the air vent to release any air trapped in the water circuit.
• Run the clean water through the water inlet and operate the pump to drain out the dirty water. Clean the strainer after
running the pump for 30 minutes.
• Fill up the water circuit after connecting the pipes and equipment. Check water leakage at all connections and joints. Do
not start the unit when the system is leaking.
• To optimize the capacity of the system, ensure that the system is free of air bubbles. The air trapped in the system would
make the system unbalanced.
