INSTALLATION AND OPERATING INSTRUCTIONS Model: KWL EC 200 Eco R KWL EC 200 Eco L with 4-level operation switch Controlled ventilation system with heat recovery.
TABLE OF CONTENTS Thank you that you have decided on Helios ventilation system with heat recovery. Read the information summarised in the operation and installation instruction before the Helios unit is put into operation. In addition, you will find information about the maintenance and care which serves the proper functioning and conservation of value of your Helios unit. INTRODUCTION General informations............................................................. Main parts and optional equipment.......
GENERAL INFORMATIONS m Importantß Important informations Operation: Important information about the ventilation system as well as settings at the controller are specified here. Maintenance: In the maintenance part important information about filter changes and necessary cleaning and maintenance activities are specified. The user usually accomplishes maintenance work.
GENERAL INFORMATIONS When screwing through the side panel, the fans, controler, heating element and electrical wiring must not be damaged or restricted in function. Sound and vibration transfer must be considered on site when installing the unit. It is necessary to connect the condensation spigot of the unit to a pipe connected to the drainage system of the house with a U bend trap in to prevent oders returning from the drains (see condensation run-off).

FUNCTIONS Models: KWL EC 200 Eco R / KWL EC 200 Eco L KWL EC 200 Eco removes contaminated air and replaces it with fresh filtered and heated outdoor air. Efficient filtering of outdoor air (G4 + F7) prevents harmful particles from entering the duct work and rooms via the unit. Good filtering of extract air (G4) diminishes the contamination of the unit and ensures proper operation of heat recovery and the extract air fans.
MOUNTING INSTRUCTIONS Mounting Location of KWL EC 200 Eco 2 1 The unit is mounted indoors, in a place where temperature does not fall below +5 °C. If installed within not heated areas (e.g. cock loft) a sufficient isolation on all sides is to be mounted outside at the unit. Otherwise condensate formation at the casing sides could occur. The condensate drainage must be laid frost protected.
FUNCTIONS 2. Function The differential pressure switch DDS monitors the pre-installed outside air filter G4 and the optional usable pollen filter F7 (intake air). It monitors the static pressure loss between out side air and intake air duct. If the air flow volume is reduced due to dirty. filters, the pressure loss decreases between the . two measuring points ( In the extreme case at V=0 Þ Dp=P1-P2=0 ). A filter signal, for example a signal lamp can be build on site. 3.

MAINTENANCE m ATTENTION: All work only in dead state! Before maintenance an isolator is required for with a minimum of 3 mm contact opening of each pole. Electrical connection should only be carried out by a qualified person. G Filter and heat recovery cell When the Maintenance reminder turns on the indicator lamp in the 4-level operation switch, check the filters. Outdoor air is filtered in the unit with two separate filters.
MAINTENANCE Other cleaning In connection with maintenance, also check the internal cleanliness of the unit: preheating and post-heating resistors, bottom reservoir and internal casing. Remove dirt with a vacuumcleaner, brush, damp cloth, etc. It is absolutely forbidden to run water into the electrical devices. Air entrance valves / air outlet valves Valves must be cleaned each year. Outdoor air vent Grills must be cleaned each year from leafs or other objects by in-coming air.
OPERATION FAILURES / ALARMS 1 CAUSE METHODE/DO THIS Outdoor air cool when entering the house. Air cools down in the attic ducts. The unit is deaf, the fans do not rotate, and none of the indicator lamps of the control panel is lit. The door switch may be broken or has not closed properly. The socket is dead; the fuse may have burned out, for instance. The heat recovery cell has frozen, and extract air cannot heat outdoor air. The extract air filter or the cell is clogged.
