Commissioning by Orcon

 

Orcon is happy to assist you in commissioning the WTU. After the installation has been 
approved  by  Orcon,  you  will  receive  an  additional  one-year  warranty.  Prior  to 
commissioning and in the event of a malfunction, you should check the following points.

 

Check the installation for the following points:

 

The WTU and all external equipment have been installed in 
accordance with the installation instructions (see pages 10 to 12).

 

The cables of the WTU are correctly connected (see pages13to 15).

 

The WTU is powered and earthed.

 

The power cables have the correct diameter.

 

An isolating switch is fitted.

 

The outside air and exhaust air ducts are insulated.

 

The silencers are installed and the duct system is correctly 
connected to the WTU.

 

The diameter of the air ducts must be equal to or larger than the 
connection flanges of the WTU.

 

The air filters are clean and the air flow is not blocked.

 

The outside air intake is located at a sufficient distance from 
contaminated air (kitchen exhaust, boiler and fireplaces, etc.).

 

There is enough space to carry out servicing. Check that the heat 
exchanger, filters and motors (via the side and bottom hatches) are 
accessible and can be replaced if necessary.

 

Only for the TA series:

 

A condensate drain is connected to the unit and that it is not 
blocked. Make sure that the reinforced hose is placed at an 
angle.

 

A CBRF preheater is installed.

 

Check whether the following data are available (or possibly set):

 

A weekly schedule with the set normal and reduced fan 
speeds.

 

Any desired configurations, such as temperature control 
functions, fan control, external control functions, etc., can be
