MTEC.3800.GB-B-1 Operation and maintenance WSA series English
WSA
Water chiller
Units are designed and manufactured to European safety and technical standards. The units have been designed
exclusively for heating and cooling. The units must be used for this specific purpose only.
The Company will not be liable for claims for damage caused to persons, animals or material goods or property
caused by improper installation, adjustment and maintenance or improper use. Any use not specified in this manual
is prohibited.
3.5 Operational limits
3.5.1 User heat exchanger water flow rate
The nominal water flow rate provided, relates to a ΔT of 5°C. The maximum flow rate allowed is one that provides a ΔT of 3°C. Higher
values may cause too high a pressure drop. The minimum water flow rate allowed is that which results in a ΔT of 8°C. Insufficient flow will
result in evaporating temperatures that are too low leading to the operation of safety devices that will prevent unit operation.
3.5.2 User hot water temperature (winter operation)
Once the system is on temperature, the minimum user water temperature should not be less than 30°C; Lower values could cause incorrect
working operation of the compressor and compressor failure may occur. The maximum user outlet water temperature cannot exceed 55°C.
higher values may call the action of safety devices which would stop the unit.
3.5.3 User cold water temperature (summer operation)
The minimum user outlet water temperature allowed is 5°C: To operates below this limit the unit should need some structural modifications.
In this case please contact our company. The maximum user outlet water temperature 18°C.
