Check and initial
adjustment of the system
In order to achieve optimal operation of the system, an
initial adjustment must be performed using professional
equipment for measuring the atmosphere.
The following items must be checked, although the system
can be put into operation before the initial adjustment has
been performed:
1. Check that the system has been correctly installed, and that
all ducting has been insulated in accordance with directions.
2. Check that various hatches can be opened so that it is
possible to perform service and maintenance on the unit.
3.
Check that filters are clean (they can be dirty after
installation), and replace as necessary before running initial
adjustments.
4. Check that the condensation drainage is correctly installed
with an appropriate water trap, and that this is protected
against frost.
5. Pour 1 l of water into the condensation tray, and check that
it flows away without impediment via the condensation
drainage hose.
Default setting if the system is started up prior to initial
adjustment:
Adjust all Supply air valves so that the valve which is
closest to the unit is open at 3 turns from the closed
position, while the one furthest away is open at 8 turns
from the closed position.
The valves in between are to be open at 4-7 turns
depending on how close they are to the unit.
Optimal initial adjustment
of the system
Professional equipment for measuring the atmosphere
must be used. Check that all 5 items in the section above
have been performed before the initial adjustment is con-
ducted. Subsequently, the system can be put into opera-
tion.
The system should be adjusted initially for basic ventila-
tion which is speed 2. In order to reduce energy consump-
tion as much as possible, the overall atmospheric volume
should first be adjusted to the desired level by changing
the speed settings in the Service Menu.
Then the initial adjustment is performed on the Supply air
and exhaust valves using measuring equipment. (Remem-
ber to lock the valves when performing the initial adjust-
ment, and that the conducting plate on the Supply air
valves is turned so that air is blown in the right direction)
Finally, the overall atmospheric volume should be re-
checked and fine-tuned by adjusting the speeds for Step
2in the Service Menu. Step 1 and Step 3 should then be
adjusted to an appropriate interval in relation to Step 2.
Requirements for the hot
water circuit
For the hot water installation, the following materials may
be used:
• Copper
• Stainless steel
• Brass
• Synthetic materials
This is naturally dependent upon the materials which have
already been used in the water circuit (of the dwelling).
Incorrect combinations of materials may result in damage
from corrosion.
This requires special attention when galvanised
components and components containing
aluminium are used.
Using the water circuit
Fill the tank at the connector spigot and air out the tank
by letting one of the uppermost hot water spigots remain
open until no more air comes out.
Re-check the entire water circuit for any leaks. .
After start-up, it is necessary to check all connections for
leaks.
The cooling circuit
The unit has been delivered ready to run. No work needs
to be performed on the cooling circuit. The control unit will
automatically assume control of all functions and start up
the compressor, ventilator fan, etc. in order to maintain the
set water temperature.
