- Electrical qualification (in accordance with regulations) for working near the unit or on the electrical components.
■ Technicians who install, commission, operate and service the unit must have received the necessary training and certification,
understand the instructions given in this manual and be familiar with the specific technical characteristics of the installation site.
■ All work on the refrigerating circuit must comply with directive EC No. 842/2006.
3.4 - Pressure and temperature
■ Maximum permissible pressures (OP):
- Water or glycol/water mix type heat exchanger: 8 bar.
- Superheated water type heat exchanger: 12 bar.
- Steam heat exchanger: 12 bar.
- Refrigeration heat exchangers: Group 2 refrigerants: 42 bar.
■ Test pressure (TP): In accordance with § 5.3.2.2 a and 6.3.3 iii of standard 378-2, the pressure test (PT) is performed on a model
representative of all assemblies in the range at 3 x PS.
■ Transport temperature: -40°C/+75°C.
■ Storage temperature: min.: -40°C, max.: +75°C.
■ Operating temperature outside the air stream:
- Normal operation: min. -20°C, max. +50°C.
- Specific operation: min. -30°C, max. +75°C (consult the manufacturer).
■ Operating temperature in the air stream:
- Normal operation: min. -20°C, max. +50°C.
- Specific operation: min. -30°C, max. +80°C (consult the manufacturer).
Our units are designed for altitudes of up to 1000 m. For higher altitudes, consult the manufacturer.
The altitude may significantly affect the unit's performance due to the air density.
