Installation instructions for professionals
Installing model eWind W
Principal, control and wiring diagrams for each model can
be found at the end of this manual.
Check the principal charts for units with fluid coil. Install and
connect the water pipes according to these charts.
Installing:
1. Install the dampers and damper motors.
2. Install and connect the water pipes.
3. Install the valve and the valve actuator.
Valve and actuator open counter-clockwise and close
clockwise. Picture shows valve and actuator in the fully
open position. Also shown is the allowed direction of the
liquid flow.
Do not install the actuator so that the manual
control knob faces downwards.
NOTE
4. Connect the water.
•
Do not connect where the water circulation stops,
eg when hot water is produced.
5. Check the water coil and its connections for leaks
immediately after the system has been filled with
water.
•
The water heating coil needs a steady flow of
sufficiently warm water without large temperature
fluctuations. Be sure to check and adjust the water
flow in the heating coil according to the technical
features table at the end of this manual.
•
Do not connect to a point where the water
circulation ends for example during hot water
production. If the water is taken for instance from
a ground source heat pump, the heating coil
needs its own circulation pump.
•
If the installation is done in wintertime it is
recommended not to let water in the coil until
the ventilation is running. This in order to prevent
cold air from entering the ventilation system and
possibly freezing the coil.
6. Connect the external cables such as the cable
between the unit and the control panel holder,
external sensor(s), actuator and pump.
•
Do not connect Modbus until all installation and
commissioning work is done.
7. Install over voltage protection to the unit.
8. Open the unit’s maintenance hatch and make sure that
•
the unit is clean from the inside
•
there are no unwanted objects inside
•
the filters are in place and
•
the condensate drain works.
9. Close the hatch carefully.
10. Connect the unit to an appropriate electric supply.
The valve and actuator must be in the same
position when connected. When the valve is in
open position, the actuator is turned counter-
clockwise before connecting, and when the
valve is closed, the actuator is turned cw before
connecting.
