3.
During insertion make sure that the identification plate of each cartridge faces towards you (i.e.
towards the door of the appliance) and the arrow indicating air flow through the cartridge always
points towards the heat exchanger!
4.
Make sure that each section (supply, exhaust) contains filter cartridges with the appropriate filtration
class as shown on the identification plate of the appliance.
5.
Record the date when the filters were replaced, e.g. in a book of unit´s operation.
Use only original filtration cartridges! If different cartridges are used, the manufacturer cannot
guarantee their proper functionality!

General rules
1.
The electrical wiring in the equipment observes valid standards for electrical connections to the
TN-
C, TN-S, TN-C, S networks. Only a qualified person possessing valid service certificate issued
by
A
irflow Developments Ltd.
may carry out the electrical wiring work. The equipment is fitted with
terminals for
external common grounding.
2.
Wiring diagram of the whole air-handling system is attached as an inseparable supplement of
documentation attached to the unit. Installation guides and wiring diagrams of optional
accessories
are included in the documentation of these accessories.
3.
A circuit-disconnecting device (a service switch) with the distance of disconnecting contacts of at
least 3 mm at all poles must be placed into the power supply to the equipment. This disconnecting
device must be located near the equipment. A standard circuit-braking device (supplied with the
equipment) may be used as such a device if the electrical panel is located is in reachable distance
from the equipment.
4.
The way of commissioning may differ depending on the regulation. Commissioning is performed
by
a trained technician based on separate documentation.
5.
You will find the description of the control in a separate documentation called „Regulation control“.
The unit shall be protected using a breaker with characteristics "C"
In case of using additional overcurrent protection against accidental direct or indirect contact, it is
necessary to use a special circuit breaker designed for frequency inverters and switching sources.
It is a protector being sensitive to alternating and pulse DC residual currents, resistant to current
surges 5 kA.

Safety rules
Ensure that the following is done prior to commissioning the equipment:
●
An initial electrical audit according to valid standards. A written report must exist about this audit.
●
Connecting ducts to equipment’s air inlet and outlet ports according to instructions stated in previous
paragraphs.
●
Filling water to condensate drain trap.
●
Fill the heating circuit including the hot water heater and regulatory coil (including external hot water
heaters in ducts equipped with regulatory coils) with heating fluid even when operating the unit out
of the normal heating period. When filling the circuit, closing fitting openings on the heater input and
output for heating fluid must be checked and air locks bled from the system
●
Checking rotation direction of each fan impeller. In case of opposite direction switch phases.
●
Checking current consumption of each fan at all speed steps. The current should not exceed the
max. value on the fan’s label. In case of exceeding the max. value properly decrease the air volume
flow in the ductwork.
●
Appliances with hot water heaters (including external hot water heaters in ducts equipped with
regulatory coils) must be permanently connected to the electricity supply to ensure antifreeze
protection of the hot water heater. In case of longer power cuts the heating fluid in both the heater
and the coil must be discharged. Discharging should be carried out using compressed air; do not
rely simply on gravity drainage!
