INSTALLATION AND SAFETY

USE

 

• For an optimal indoor climate and to avoid moisture damage in the property, 

 

  there must be continuous and adequate air exchange. The unit 

must

 be run-

 

  ning continuously and only stopped for service. 

 

  The airflow is controlled via various settings on the control panel:

 

 

Reduced 

– Reduced airflow, can be used when no one is in the property.

 

 

-

 Normal

 – This is set by the installer and should not be changed by the user.

 

 

-

 Boost

 – Higher airflow than normal, medium/max can be selected. This 

 

    should be used when the load on the property is higher than what the 

 

    standard mode is set for, e.g. when there are more people than normal in 

 

    the property. 

 

• When installing HERU

®

, follow applicable regulatory requirements and 

 

  recommendations concerning location, access, duct insulation, etc. 

 

• The user may, in accordance with IEC 60335-2-40, independently perform 

 

  the service and maintenance on HERU

®

 that is described in this user manual. 

 

  However, the unit must be disconnected from any power supply before all 

 

  such work. With reservation according to IEC 60335-2-7.12 ”This appliance is 

 

  not intended for use by persons (including children) with reduced physical, 

 

  sensory or mental capabilities, or lack of experience and knowledge, unless 

 

  they have been given supervision or instruction concerning use of the appli-

 

  ance by a person responsible for their safety. Children should be supervised to 

 

  ensure that they do not play with the appliance.”

 • 

HERU

®

 should be kept in a sheltered and dry environment during storage 

  

before 

installation.

 

• Dimensioned airflow should not exceed 75% of the unit’s maximum capacity.

 

• Check regularly to ensure that supply air and extract air are functioning 

  

properly.

 • 

To avoid condensation in the unit in cold weather, the unit should not be 

 

  turned off for a prolonged period of time. 

If the unit is installed during cold 

 

  weather and not operated immediately, the ducts should be plugged to pre-

  

vent 

condensation.

SAFETY

 

• Maintenance and operation of the unit may only be performed by personnel 

 

  who have the requisite knowledge concerning maintenance of the ventilation 

 

  unit and who have read this manual.

 

• Consider the weight of the unit when installing. See technical specification for 

  

weight 

data.

 

• Bear in mind that HERU

®

 and the fan housing may have sharp corners and 

  

edges. 

 

• Before commissioning, make sure there are no foreign objects inside the unit 

 

  which could cause serious injury or damage to the unit.

 

• Always follow the electrical safety regulations concerning free clearance for 

 

  control cabinets and electric heaters.

 

• Make sure that the unit is always locked and that the keys are stored in a 

 

  location that is not accessible to unauthorized persons.

 

• Do not open the service doors while the unit is in operation. Overpressure 

 

  from the fans could cause the doors to swing open.

 

• The unit should be fitted with a locking safety switch placed nearby.

 

• Turn off the unit via the control panel and wait two (2) minutes before 

 

  opening the service doors 

 

• The safety switches must be switched off and locked before starting any 

  

service 

work. 

 

• Do not use the safety switches for normal start and stop of the unit. 

 

• Electrical installation, electrical and mechanical work and work inside the unit 

 

  and its peripheral equipment may only be performed by certified electricians 

 

  or personnel designated by H. Östberg AB.

 

• Note that the surfaces of the unit may be cold in winter conditions. 

 • 

HERU

®

 contains 

rotating parts that could cause serious injury in the event 

  

of 

contact

. The unit must therefore be connected to a duct, the doors closed 

 

  and locked and the key removed.

 • 

The heating coil in the unit could cause burns.

 The heating coil may still be 

 

  hot after the voltage has been switched off for service, maintenance and repair 

 

  work (approx. 60°C).
