Residual risks

WARNING:

Lift and transport the units packed in an upright position very carefully.

Handle high units very carefully. Never place them on an inclined or uneven plane.

Danger of falling. See section Transport and storage.

WARNING:

To avoid the falling of a wooden box (optional for Solar SR™):

  • Stack max 3 units on top of the other.
  • Place the packages in line.

Always store the packages on a level surface.

See Wooden box available only for AlfaSolar SR™.

WARNING:

Before lifting the unit, check its weight from the transport documents or from the product nameplate and make sure that the lifting device, crane or truck is appropriate.

  1. Only use lifting equipment that is equipped with appropriate labels.
  2. Ensure that the belts or slings with hooks used for lifting keep the equipment balanced.
  3. Do not lift the unit with a crane before removing the pallet from under the unit.

Do not stand under the unit when it is hanging.
WARNING:

Always install the units in a place with no entrance for outsiders.
WARNING:

Do not walk or step over unprotected heat transfer section, since besides being damaged it can generate an accident or a risky situation.
WARNING:

If you must step on the unit for maintenance purposes, always wear safety shoes.

Use proper safety devices that prevent falling.

Do not step over SM/SRM™ units.
WARNING:

Before switching on the unit, always ensure that everyone is at a safe distance from the unit.
WARNING:

Risk of slipping or falling down.

WARNING:

Each fan is equipped with a fan guard and a lockable service switch. The wire spacing in the fan guard and the safety distance of the blade correspond to the European safety standard. The safety guards are protections from contact only.

Do not remove the safety guard before the fan is shut down. The rotating impeller may catch in your clothes, cut you or pull you in.
WARNING:

Breaks in pressure pipes or components may cause injuries. Do not exceed the unit design pressure. Only perform maintenance work on pressurized parts when the unit is empty.
WARNING:

In operation, the heat transfer section and pipe temperatures exceed 45 °C. Contact may cause burns. Use hand protection.

Hot air over the unit when the unit is operating. Never work a long time over the unit when it is operating.
WARNING:

Only an authorized electrician may perform the electric connections.
WARNING:

Before starting the service operation, ensure that the electrical supply is reliably isolated; use the lockout/tag-out system. Always check with a voltmeter that the unit is electrically isolated and shut off.
WARNING:

Ensure free space in front of the electrical cabinet according to local regulations.
WARNING:

EC-fans: Electrical load (>50 μC) between mains wire and protective earth connection after switching of the supply when switching multiple devices in parallel.

Electric shock, risk of injury. Ensure that you have sufficient protection against accidental contact.

Before working on the electrical connection, short the connections to the mains supply and PE.

EC-fans: Terminals and connections have voltage even in a unit that is shut off.

Electric shock. Wait for five minutes after disconnecting the voltage at all poles before opening the device.
WARNING:

Fans with Inverter: Terminals and connections have voltage even in a unit that is shut off.

Electric shock. Wait for 15 minutes after disconnecting the voltage at all poles before opening the device.
WARNING:

EC-fans: High temperature at the electronics enclosure. Danger of burn injuries. Ensure that you have sufficient protection against accidental contact.

WARNING:

Cutting and crushing hazard when removing the spare parts from the packaging. Wear safety shoes, safety helmet and cut-resistant safety gloves.
WARNING:

Follow the recommendation of the working fluid supplier (Material Safety Data Sheet) strictly.

Prevent the accidental release of fluid and adopt the visual and acoustic alarms to minimize the consequences of insufficient amount of fluid. Plan the installation field for recovering or disposing of the fluid.
WARNING:

Before washing the heat transfer section, read the Material Safety Data Sheet of the detergent and follow the manufacturer´s instructions.

When vacuum-cleaning and washing the heat transfer section, use protection glasses, safety gloves, safety shoes and other personal protection.
WARNING:

Depending on the installation and operating conditions, a sound pressure level greater than 70 dB(A) may arise. Use appropriate ear protection.
WARNING:

Sharp edges. Use protection glasses, safety gloves, shoes and clothes.
WARNING:

Ensure that the unit is electrically isolated and dead before discarding and demolishing it.
WARNING:

Do not lift the unit before it is fully empty.
WARNING:

Before moving to the solution, ensure that the unit is in safe condition. See Residual risks.
  • The cables may carry voltage even when the unit is powered off.
  • The action service switch on/off restarts the machinery/fan. Take appropriate precautions.
  • All the main pressure bearing parts of the air heat exchanger (AHE) are designed according to PED 2014/68/EU and Harmonized standards only for internal pressure within the limits of maximum design pressure (PS) and maximum operation temperature (TS) pointed out in the nameplate (positive pressure).
  • The end user is responsible for adopting the suitable safety devices against overpressure and overheating (i.e. safety valves).
  • The stop/emergency stop device is not supplied by the manufacturer, because the total process risk may increase or a new risk would be introduced by the action of a localized stop/e-stop system.
  • S-models without service switches (and without SW or cabinet options): The end user is responsible for securing the equipment, that is, for switching off the installation/machine where the fan is installed and for securing it from being switched on again.
  • The end user is in charge of the periodic inspection of the safety devices installed on the air heat exchanger (AHE) according to the national regulations.
