¶ SAFETY
When using the units, the instructions in this regulation must be followed.
• During installation, electrical connection, commissioning, repair, and maintenance of the units, applicable standards, safety regulations, and generally accepted technical rules must be observed!
• The installation of the units, including the connection of the electrical installation, commissioning, repairs, maintenance, and operation, may only be performed by an individual or legal entity with valid certification!
The following general instructions are considered essential. Additional recommended instructions are detailed in the installation, commissioning, and maintenance sections.
Before starting the unit, the following must be met:
• All service panels and doors of the unit must be securely closed.
• Ensure that no persons are inside the unit or in the dangerous area around the unit.
• Instructions for the first start-up and commissioning, as well as maintenance instructions, are provided in the relevant sections of this manual.
The unit must not be operated under the following conditions:
• The unit is located in an area with a risk of explosive atmospheres (does not apply to ATEX units).
• The unit is placed near magnetic fields.
• The air entering the unit contains aggressive gases or chemical particles, or the air temperature is below -30°C and above +50°C, or the humidity of the exhaust air is too high (not intended for removing humid air, such as in pool operations, etc.).
It is not possible to enter the unit or perform any work on it unless the following points are met:
• The unit must be disconnected from electrical power.
• All rotating parts (fans, rotary heat exchangers, etc.) must be at a standstill.
• For fans and electric motors equipped with frequency converters, a minimum waiting time of 15 minutes is required due to residual voltage.
• Protection against accidental unit start-up (e.g., lockable service switch) must be ensured.
• Heat exchangers and hydraulic system components must be cooled to ambient temperature, with a maximum surface temperature of +40°C.
• The pressure in pressurized systems must be equalized to atmospheric pressure.
• Personnel must be equipped with appropriate protective gear.
• There must be no explosive atmosphere inside the unit.
