If the installation requires a useful head higher than that obtained by installing a pump assembly and storage
tank, it is recommended that an additional pump is installed on the unit. Provided the additional pump
installed inside of unit, the pump must be connected close to plate heat exchanger. Provided the pump
installed outside of unit, the pump shall be connected at water pipe's outlet. The pump can be easily
installed in the unit by removing the pump connection pipe. Connect to terminal PL, PN on the electric panel.
Important
1) The chillers must be provided with a filling/top-up system connected to the return line and a drain cock in
the lowest part of the installation. Installations containing anti-freeze or covered by specific legislation must
be fitted with hydraulic disconnections.
2) The manufacturer is not liable for obstruction, breakage or noise resulting from the failure to install filters
or vibration dampers. Particular types of water used for filling or topping up must be treated with appropriate
treatment systems.
14.4 Design of the store tank in the system
kW is the unit for cooling capacity, L is the unit for (G) minimum water flow volume in the formula.

Comfortable type air conditioner
G= cooling capacity×2.6L
Process type cooling
G= cooling capacity×7.4L
In certain occasion (especially in manufacture cooling process), for conforming the system water

content requirement, it's necessary to mount a tank equipping with a cut-off baffle at the system to avoid
water short-circuit, Please see the following schemes:
14.5 Chilled water flow
Minimum chilled water flow
The minimum chilled water flow is shown in the below table.
If the system flow is less than the minimum unit flow rate, the evaporator flow can be recalculated, as shown
in the diagram.
