3 OPERATING LIMITS
3.1 Storage
If the unit needs to be stored before installation, it is necessary to follow some precautions:
- Do not remove the protective plastic.
- Protect the unit from dust, bad weather and any rodents.
- Do not expose the unit to direct sunlight.
- Do not use heat sources and / or open flames near the machine.
Although the unit is covered with a heat-shrink plastic sheet, it is not intended for long-term storage and must be removed
and replaced by tarpaulins or the like, more suitable for a longer period.
Environmental conditions must be within the following limits:
Table 9– Units environmental conditions
Minimum ambient temperature
-20°C
Maximum ambient temperature
+56°C
Maximum R.H.
95% not condensing
Storing below the minimum temperature may cause damage to components. Storing above the maximum temperature
results in safety valves opening, with subsequent refrigerant loss. Storing in a humid atmosphere may damage electronic
components.
3.2 Operation
TZD range of chillers is available with three refrigerants:
- R1234ze (EWAH)
- R134a (EWAD)
- R513a (EWAS)
The following mentioned values represent a guideline, please refer to the Chiller Selection Software for real operating
limits for the specific model. For free cooling units, the free cooling mode can be activated only when the ambient air
temperature is at least 0÷10 °C lower than the outlet water temperature.
As a general rule, the unit should be operated with an evaporator water flow rate between 50% and 120% of nominal flow
rate (at standard operating conditions), however check with the chiller selection software the correct minimum and
maximum allowed values for the specific model.
Operation out of the mentioned limits may damage the unit.
In case of any doubt, contact manufacturer representative.
EWAH-TZD

Outside ambient air temperature
ELWT
Evaporator leaving water temperature
Ref 1
Operation with ELWT < 4 °C requires Option 08 (brine) and glycol
Ref 2
Operation with ELWT > 18 °C requires Option 187 (high evaporator leaving water temperature)
Ref 3
Operation requires option 142 (High ambient temperature kit)
Ref 4
Operation at outside ambient air temperature < 5 °C requires option 229 (fan speed modulation) or option 42
(Speedroll)
The charts shown in these pages constitute a guideline on operating limits in the range.
Refer to the Chiller Selection Softwareselection software for the actual operating limits in the working
conditions for each model.
