Electrical installation
The electrical connection must be carried out by an
authorised electrical engineer.
See accompaning electric diagram.
The cable between the unit and the control panel is a 4-
conductor cable for Optima 250, with a maximum length
of 50m and a 8-conductor cable for Optima 100 with a
maximum length of 10m.
Inspection and initial adjustment of appliance
To achieve optimum running of the unit it must be initially
adjusted with air measuring equipment.
To start up the unit before adjustment, do as follows:
Before starting up the unit:
1: Check that the Genvex unit is correctly mounted and
that all ducts are insulated as required.
2: Check that hatches can be opened so that service and
maintenance on the unit can be carried out.
3: Check that filters are clean (may be dirty from
installation work).
4: Check that the condensate drain is correctly mounted
with water trap and is protected from freezing. Pour 1
litre water into the condensate tray and make sure it
can run unhindered through the condensate drain pipe.
5: Set all supply valves such that the valve closest to the
unit is opened three turns from closed position, while
the furthest is open eight turns from closed position.
Open the intermediate valves by 4-7 turns depending
on how far they are from the unit.
6: If a reheating surface has been mounted on the unit,
set the supply temperature to 0-3°C below the room
temperature in the dwelling.
The unit can now be started up and be allowed to run until
initial adjustment with air measurement equipment has
taken place.
Optimum initial adjustment of plant
Air measuring equipment is used.
Before starting initial adjustment, check that the 6 points
in the inspection and initial adjustment section have been
carried out. Then start up the unit:
