BLAUBERG Ventilatoren GmbH Company is happy to offer your attention 

a new heat recovery air handling unit 

KOMFORT EC SKE270-1.5

 with 

integrated kitchen hood.

INTRODUCTION

The present operation manual contains a technical description, technical 

data sheets, operation and mounting guidelines, safety precautions and 

warnings for safe and correct operation of the unit.  

Read carefully and understand the operation manual, especially the safety 

requirements, before the unit mounting and start up.

Keep the operation manual available as long as you use the unit.

GENERAL

The heat recovery air handling unit KOMFORT EC SKE270-1.5 with integrated 

kitchen hood is designed for efficient and energy saving ventilation of 

domestic premises. 

The unit is not a ready to use product but a component part of central air 

conditioning and ventilation network. 

The unit is designed for wall mounting. 

The unit is available for round Ø125 mm air ducts.

The unit is rated for indoor application at ambient temperature from +1 °C 

up to +60 °C and relative humidity not exceeding 80%. The transported air 

temperature is allowed from -25 °C up to +60 °C.

Hazardous parts access and water ingress protection rating:

  Unit motors - IP 44;

  Assembled unit connected to air ducts - IP 22.

The unit design is regularly improved, so some models can slightly differ 

from those ones described in this service instruction.

SAFETY RULES

All operations related to the unit electrical connections, servicing and 

repair works are allowed only after the unit disconnection from power mains.  

The unit is rated as a Class I electrical appliance.

All mounting and servicing operations are allowed by duly qualified 

personnel. 

Please follow the safety regulations and working instructions (DIN EN 50 

110, IEC 364).

Make sure the impeller and the casing are not damaged before connecting 

the unit to power mains. The casing internals must be free of any foreign 

objects which can damage the impeller blades.

The unit maintenance and repair is allowed only after power cut-off and full 

stop of the rotating parts.

Misuse of the unit or any unauthorized modification are not allowed. 

The unit is designed for connection to ac single-phase power mains, see 

«Technical Data». 

The unit is rated for permanent operation.

Take steps to prevent ingress of smoke, carbon monoxide and other 

combustion products into the room through open chimney flues or other 

fire-protection devices. Sufficient air supply must be provided for proper 

combustion and exhaust of gases through the chimney of fuel burning 

equipment to prevent back drafting.  The maximum permitted pressure 

difference per living units is 4 Pa.

The transported air must not contain any dust or other solid impurities, 

sticky substances or fibrous materials.
