22 Operation
4.4 Start up for daily operation
It is assumed that initial commissioning has been carried out properly by the service technician of your
Nortec representative.
If the Nortec ME Control has been out of operation for a prolonged period of time, a complete
system service has to be performed prior to the start up.
The following description outlines the start up procedure for daily operation. Proceed as follows to pre-
pare the Nortec ME Control for operation:
1. Switch off AHU.
2. Examine the Nortec ME Control for possible damage and faulty installation. Ensure tank is empty.
DANGER!
Damaged systems or systems with damaged components or faulty installations may present danger
to human life or cause severe damage to material assets.
Damaged systems and/or systems with damaged or faulty installation must not be operated.
3. Close doors of AHU if open, then switch on AHU if switched off.
4. Open shut-off valve in the water supply line.
5. Make sure the front panel of the control unit is mounted and fixed with the retaining screw.
6.
Switch on the electrical isolator in the mains supply line (mains supply to control unit).
7. Switch <Control unit On/Off> and <Humdification/Cooling On/Off> switch on the control unit to
“ On”, and activate control unit via the external enable switch if necessary. Check for any fault or
service message.
8. If Nortec ME Control has been disconnected from the mains for more than 48 hours the message
“Out of Commissioning” appears. If this is the case proceed as follows:
• Switch off control unit via the
<Control unit On/Off> switch.
• Risk assess the system and check the need for disinfection.
• Close shut-off valve in the water supply line.
• Disconnect water supply line from the connector on the hydraulic module.
Caution should be
taken to ensure no splashing is created.
• Connect hose to the open end of the water supply line and lead the hose into open tundish
outside the AHU.
• Open shut-off valve in the water supply line and flush water supply line an appropriate length of
time. Then, close shut-off valve again, remove hose and reconnect supply line to the connector
on the hydraulic module.
• Switch on control unit via the <Control unit On/Off> switch.
Note: After switching on the control unit the “Out of Commissioning” message appears again, how-
ever the message is reset automatically after 1 minute and the Nortec ME Control continues with
normal operation.
The Nortec ME Control is now in normal operating mode and the standard operating display is shown.
