Product description
Because of their low construction height, EASYAIR®flat air handling units are intended for ceiling installation.
The unit design consists of functional modules (filter, fan, silencer, heater, cooler, heat recovery). The devices can be ordered optionally as combined supply and exhaust air systems including heat recovery or simply as air supply and exhaust
air systems.
The units with heat recovery achieve a high degree of heat recovery. Thus the units make a considerable contribution to
energy savings and a reduction of operation costs.
All units can be ordered with the appropriate control devices. This ensures trouble-free unit operation.
All field devices come ready assembled with the unit. The switch cabinet comes as a separate unit and can thus be
installed wherever best suits the client. The wiring installation between the unit and switch cabinet must be supplied by
the client.
Optional extras allow the units to be extended.
Optional components to extend use consist of: acoustically isolated unit connections, dampers, electrical or waterheated heater module, cooler module, silencer module, pressure sensors for pressure or constant volume regulation, air
quality sensor, room temperature sensor, etc.
When using the associated control system, filter replacements which become necessary are displayed by the pressuredifference filter monitoring device. All control functions are included in the control software and their parameters can be
set. By means of pre-configured bus systems, the control system can easily be integrated into higher-level systems: the
user can choose between Modbus, LON, BacNet/Ethernet.
Our products are subject to constant quality control and comply with the applicable regulations.

5.2.3 Duct connection
For PF- and GF units the duct system channels the outdoor air into the air handling unit and into the building as supply
air. The extract air is passed through the unit for heat recovery and channeled outside as exhaust air.
For EF units the duct system channels the outdoor or room air (recirculation) to the ahu and into the building / room as
supply air.
Equipotential bonding between the device and the drain must be established with the grounding strip supplied.
Duct connections (optional)
Sound-isolated duct connections are available for all EASYAIR®flat units, which use the entire available unit crosssection.
These duct connections must be fixed with enclosed drilling screws to the casing.
Connection of the ducts to the unit must be properly performed.
Requirements for the duct system
The ventilation system should be designed for slow air velocities and low pressure drop to boost efficiency, energy
consumption and air output.
Pulleys near the device should be avoided.
All connections between ducts and air handling unit are to be executed accurately and securely.
Condensation protection / thermal insulation
For PF- and GF units the outside and exhaust air ducts must always be well insulated to prevent condensation. It is
particularly important to carefully insulate all pipelines leading directly to the unit and to cold rooms/zones.
For EF units that are used for cooling issues the supply air duct must be insualted.
Generally speaking, all air ducts carrying cold air must be insulated.
5.2.4 Siphon connection
EASYAIR®flat heat recovery and cooler modules are provided with a condensate tray and a condensate pipe in the operating panel. This condensate pipe comes in the form of a snap-on coupling. This allows quick and easy connecting /
disconnecting of the condensate drainage pipe to the device.
It is possible to push-fit a 14 mm outside diameter drainage tube directly into this connector.
As delivered, a short length of plastic 14 mm outside diameter drainage tube is inserted in the connector, so that it is
possible to simply fit a commercial hose with 14 mm inside diameter onto this plastic hose using a hose clip.
Condensate outflow pipes must be connected to the waste-water system using an s-bend (supplied by client).
If this is not possible because of lack of space, a condensate pump (supplied by client) should be used.
In order to prevent an intake or outtake of air from the closed drainage system, the height of each siphon must
be designed for the negative or over pressure of the air handling unit.

Checking components
All installed components are to either be easily accessible for inspection or extractable after removing the maintenance
doors from the unit.
The objective of regular hygiene checks is to detect and eliminate hygiene issues early on through frequent visual inspections or random microbiological checks.
Regular hygiene control includes the following measures:
Visual inspection of the unit for hygiene issues such as bacterial growth or contamination, rust build-up, calcium
deposits and damage.
Components identified as dirty during the hygiene inspections must immediately be cleaned.
8.5.1 WWE / KWK
Attention!
The use of high-pressure washers with conventional jet nozzles is not permitted due to risk of damage!
Corrosion may occur in the heat exchangers after longer periods of downtime due to sulfate-reducing bacteria.
These sulfides aggressively corrode welded joints and copper-based material.
We recommend the following measures to reduce this type of copper corrosion:
„„ Using sulphate-free water in the entire circuit
„„ Ensuring there are no leaks in the system.
„„ Avoiding long periods of downtime for filled circuits.
„„ Avoiding frequent re-filling with fresh water.
„„ Using material-tolerant inhibitors or biocides.
8.5.2 Plate heat exchanger
The heat exchanger can be cleaned with a hot-water, high-pressure cleaner. The following parameters must be met:
Nozzle:
Flat jet nozzle
Pressure:
max. 20 bar
Amount of water:
max. 450 l/h
Water temperature:
max. 70 °C
Distance from the heat exchanger:
min. 30 cm

Attention!
The specified values must be met, otherwise the plate heat exchangers may be damaged.
Cleaning agents (i.e. all-purpose cleaners, biodegradable) may be used to remove stubborn dirt.
Plenty of fresh water must be used for rinsing afterwards!
Do not use any aluminum cleaners! They are acidic and corrode the surfaces of the plate heat exchanger.
8.5.3 Dampers
Regularly clean dampers.
Attention!
When the dampers close, do not reach inside the slats with your hand during operation or servicing. Danger
of crushing!
8.5.4 Drip separator
The drip separator can be pulled out for maintenance reasons.
8.5.5 Fans
Regularly clean ventilation rotors, the motor and the motor base.
8.6
Replacing components
8.6.1 Replacing filter bags
Filter bags are generally to be replaced once they have reached the permissible end pressure difference.
Do not wash out and reuse used air filters. They must always be replaced with new air filters. The hygienic
requirements will not be met otherwise!
„„ Open or unhook the operating panel; see "5.1 Opening / removing the operating panel"
„„ The filter can be pulled downwards out of the housing by pulling on the filter bag frame.
„„ Clean and inspect the filter seals. Replace any damaged seals.
„„ Insert new filter bags and hold them in place by spanning them across the filter frame.
Attention!
Only use original consumables and replacement parts.
Safe operation can only be ensured in this way. The warranty may be invalidated!
