HYDRAULIC CONNECTION
4.1. Hydraulic Connection To The Exchanger
I M P O R T A N T
The water inlet must be installed where the connection is marked with the following plate:
I M P O R T A N T
The primary circuit should be set up in such a way as to guarantee a constant flow of water
to the exchanger in all operating conditions. If this is not the case, there is a risk of refrigerant
returning in the liquid state to the compressor input which could damage the compressor.
W A R N I N G !
Do not operate hydraulic connections with open flame near or inside the unit.
I M P O R T A N T
To ensure the correct operation of each pump on the machine:
• Before starting check that the pump shaft rotates freely, without mechanical impediments.
• Do NOT run the pump dry, unprimed and below the minimum nominal water flow rate.
• Do NOT operate the pump with closed shut-off valves, suction side and delivery side.
• It is forbidden to use the pump in case of cavitation.
• It is mandatory to fill and bleed the hydraulic circuit correctly before starting the pump.
4.2. Minimum Source Water Content In The Plant
For water source units or air source with cool recovery, it is important to maintain a minimum
water volume in the source loop to ensure sufficient compressor runtime. The compressors can
run intermittently; this is because the amount of heat power required by the system is not
generally the same as that provided by the machine
.
The formula below is for calculating the minimum water content on the source loop. If the actual
pipe volume is less than required, a buffer tank is required.

NOTE:
This formula is for the volume of storage for cold source water on W models or A
models equipped with cool recovery option.
Buffer tanks must be properly insulated to prevent condensation and to not have an adverse
effect on system performance.
