3.1.2.2 Safety instructions – Installation

Comply with the general locally applicable building, fire, safety and installation
regulations of the relevant local authorities, the regulations of the water and electric
utilities and all other official regulations.

Pull the unit’s plug from the mains socket to separate the unit from the power supply.
If the unit does not have a plug, use a switch according to EN 60335-1 (with
separation of all three poles and 3 mm clearance, over-voltage category III).

Always disconnect the unit from the power supply prior to commencing maintenance
or repair activities. If the unit is operated while open, there is hazard of injury.

Make sure that the FOCUS unit cannot switch on unintentionally.

To eliminate the risk of coming into contact with the running fans, the air ducts must
be fastened to the unit before the power supply is connected, observing a minimum
length of 900 mm.

Therefore, always apply measures to prevent electrostatic discharges when working
on the electronics. Wear an antistatic wrist band, for example. Static energy can
cause damage to electronic components.

The entire installation must comply with the applicable (safety) regulations from the
following sources:
- local EU standard for safety features for low voltage systems;
- Mounting/installation manual of the manufacturer (see the back cover of the
instruction manual for the contact data of Zehnder).

A socket with grounding at a distance of 1 meter or no more than the length of the
included mains cable must be present.

For safety reasons do not use an extension cable.
Installation conditions
The following conditions must be considered when deciding whether a unit should be installed in a specific area to
ensure the correct installation of the unit.
•
Ensure that the temperatures in the installation area are in the permissible range year-round. The information
regarding the permissible temperature can be found in the “Technical specification” table.
• When choosing an installation location, it is recommended that you avoid areas with a high average level of
humidity (ambient conditions for indoor climate control system must not continuously exceed 70% RH at 22 °C).
•
The unit must not be installed in rooms subject to explosion hazards.
• Inside wet rooms, the unit may only be installed outside of protection zones 1 and 2 in accordance with DIN
57100/VDE 100 Part 701.
• Connect the unit to a power source with 230 V/50 Hz.
•
Check whether the electrical installation is suitable for the maximum output of the unit. The values for the
electrical input power can be found in the “Technical specification” chapter.
• Check that the installation area of the unit meets the requirements in the “Installation requirements” chapter.

Product description
The FOCUS unit is a ventilation unit with heat recovery for healthy, well-balanced and energy-saving comfort
ventilation. A comfort ventilation system extracts foul-smelling waste air from areas such as kitchens, bathrooms and
toilets and conveys an identical quantity of fresh air into living rooms, bedrooms and children's rooms. A highly
efficient cross-counterflow heat exchanger made from plastic is used for waste heat recovery. An optional summer
box module can be used instead of the heat exchanger for thermal separation of the two airflows. The housing is
made from sheet metal with an anthracite powder coating. The high-quality polypropylene inner lining ensures the
necessary thermal insulation and unit soundproofing.
The FOCUS unit has two maintenance-free 230 VAC centrifugal fans with an integrated power supply unit and
electronic commutation. The fans run at a steady volume flow to keep the air volume constant at any selected fan
speed. The air volume is not affected even if the filters become soiled.
The unit contains filters according to EN ISO 16890 of the filter class ISO Coarse for the outdoor air and the extract
air. These consist of a synthetic non-woven filter medium with a polypropylene frame. As an option, filters of filter
class ePM1 can be used for the outdoor air. The filters are accessed via the front panel.
