30. It is not permitted to walk or rest other objects on the machines
31. The user is responsible for overall evaluation of the risk of fire in the place of installation (for example, calculation of
the fire load).
32. During transport, always secure the unit to the bed of the vehicle to prevent it from moving about and overturning.
33. The machine must be transported according to the regulations in force considering the characteristics of the fluids
in the machine and the description of these on the safety data sheet.
34. Inappropriate transport can cause damage to the machine and even leaking of the refrigerant fluid. Before starting
up, the machine must be checked for leaks and repaired accordingly.
35. The accidental discharge of refrigerant in a closed area can cause a lack of oxygen and, therefore, the risk of
asphyxiation: install the machinery in a well-ventilated environment according to EN 378-3 / ISO 5149-3 and the
local regulations in force.
36. The installation must comply with the requirements of EN 378-3 / ISO 5149-3 and the local regulations in force.
1.2 General description
All EWYT~CZ / EWAT~CZ machines are built in accordance with the main European Directives (Machinery Directive,
Low Voltage Directive, Electromagnetic Compatibility Directive, Pressure Equipment Directive.
The unit purchased is a Heat Pump, that is a machine designed to cool/heat the water (or a water-glycol mixture) within
certain limits which will be listed below. The unit operates based on the compression, condensation and evaporation of
the coolant gas as per the Carnot cycle and is composed mainly of the following parts depending on the Mode of
Operation.
Cooling or Conditioning Mode:
• One or more scroll compressors which increase the pressure of the refrigerant gas from evaporation pressure to
condensation pressure.
• A condenser where the refrigerant gas condenses under high pressure and transfers heat to the air.
• An expansion valve which allows the pressure of condensed liquid refrigerant to be reduced from condensation
pressure to evaporation pressure.
• An evaporator, where the low-pressure liquid refrigerant evaporates and chills the water.
Heating Mode or Heat Pump:
• One or more scroll compressors which increase the pressure of the refrigerant gas from evaporation pressure to
condensation pressure.
• A condenser where the refrigerant gas condenses under high pressure and transfers heat to the water.
• An expansion valve which allows the pressure of condensed liquid refrigerant to be reduced from condensation
pressure to evaporation pressure
• An evaporator, where the low-pressure liquid refrigerant evaporates.
• The operation of the heat exchangers can be inverted using the 4way valve, with which the use of the
heating/cooling unit can be seasonally inverted.
All units are fully assembled in the factory and tested before shipping. The EWYT~CZ / EWAT~CZ range consists of
models with a single cooling circuit and models with two cooling circuits.
The machine uses R32 refrigerant fluid suitable for the entire field of application of the machine.
The controller is prewired, set up and tested at the factory. Only normal field connections such as piping, electrical
connections and pump interlocks are required, simplifying installation and increasing reliability. All safety and operation
control systems are installed at the factory in the control panel.
The instructions in this manual are applicable to all models in this series unless otherwise specified.
1.3 Information about the refrigerant
This product contains R32 refrigerant that has a minimal environmental impact, thanks to its low value of Global Warming
Potential (GWP). According to ISO 817, R32 refrigerant is classified as A2L, which is slightly flammable, since the flame
propagation rate is low, and nontoxic.
R32 refrigerant can burn slowly when all the following conditions are present:
• The concentration is between the lower and upper flammability limit (LFL & UFL).
• Wind velocity<propagation of flame velocity
• Energy of the ignition source>Minimum ignition energy
But pose no risk under the normal usage conditions for air conditioning equipment and work environment.
