If there is any damage or even a suspicion of damage, the recipient must indicate this on the consignment note and have it countersigned by the haulier. The recipient of the goods must notify WOLF of the relevant facts without delay. - Page 23 11 Delivery/Handling Transport external units Transport ropes with a minimum length equivalent to the eye bolt distance L must be used when transporting external CRL units with eye bolts. The same applies to the individual transport units of the CRL evo max units. External CRL evo max units may only be lifted as an entire unit with a lifting beam when pulling equally and vertically on all available eye bolts.

1000 V DIN VDE 0105-100 Operation of electrical systems Only original WOLF accessories may be used (electric coils, servomotors, etc.), otherwise WOLF cannot accept any liability. In addition, ÖVE regulations and the local building code apply to Austria. - Page 38 - Actuator, heating / cooling - Heating circuit pump / cooling circuit pump - As well as all other system-specific functions The WOLF warranty will be void if the function test is not carried out correctly. Fans Use tools to tightly seal the doors before commissioning (unit tightness), otherwise there is a risk of motor overload.
- Page 39 17 Commissioning Electric reheating coil (accessory) To prevent the electric heating coil from switching off, never operate the CRL below its minimum air flow rate. Follow the relevant safety regulations for electric heating coils. The electric heating coil must be protected from moisture and water. Type 1300 2500...
- Page 40 17 Commissioning Heat recovery function A rotating cylinder mass (rotor material corrosion-resistant aluminium alloy, with thermal wheel heat wound in corrugated and smooth layers) absorbs heat from the extract air flow exchanger and transfers it to the outdoor air. The rotor mass is sealed by a circumferential labyrinth seal.
- Page 41 17 Commissioning Flow rate calculation The flow rate is calculated using the effective pressure method. This involves comparing the static pressure upstream of the inlet nozzle with the static pressure in the inlet nozzle. √Dp The flow rate can be calculated from the effective pressure Δp (differential pressure of the two static pressures) using the following equation.
