If the Air Curtain is set-up for :-
Inlet Air Temperature Control
or
Room Air Temperature Control
(air curtain has been modified during commissioning)
with a PAR-31MAA Remote Controller, BMS or Centralised Controller :-
Switch the Mode Button on the PAR-31MAA Remote Controller to ‘HEAT’ and adjust
the target temperature to 28°C maximum setting using the
+ Temp.
Button. Check
that the air stream from the discharge grille warms up across the whole length of the
air curtain after approximately 15 minutes of operation and that the air stream reaches
right down across the doorway with the door open or closed.
If the end user is to operate the air curtain with a Remote Controller it can be set-up to
monitor room air temperature at the controller instead of return air temperature at the
air inlet of the air curtain. If this is required see the Mitsubishi Electric remote controller
instructions for details.
If it is intended that the air curtain is to ever operate in cooling mode* switch the Mode
Button on the PAR-31MAA remote controller to ‘COOL’ and adjust the target
temperature to 14°C minimum setting using the
- Temp.
Button. Wait for the air
curtain air stream to go cold. Check there is no debris in the outlet spout, there are no
kinks in condensate hoses and the condensate pump (if used) will operate. It is
unlikely that condensate will fill the drain tray straight away so it will be necessary to fill
the tray manually with water to see if the condensate removal system is working
satisfactorily. If an alarm sensor is fitted in the drain tray, check it operates to stop the
air curtain cooling if the drain tray becomes too full. Test the air curtain for a time in
cooling mode with all the panels and grilles fitted and if environmental conditions
permit check that condensate is being collected and pumped away by the condensate
pump. No condensate should leak out of the air curtain. At the end of the cooling test
remove the inlet grilles and the bottom access panel and check that the inside of the
air curtain has remained dry and that all condensate was collected by the removal
system.
*
For the air curtain to operate in cooling mode the plug must be removed from CNX5 on the PAC-IF010
Interface PCB (see Wiring Diagrams). There must also be a condensate disposal system fitted.
To conserve energy and carbon resources it is recommended to set up the PAR-
31MAA Remote Controller, BMS System or Centralised Controller so it operates in
HEAT Mode at a target temperature of 24°C. This is the normal mode of operation for
the heat pump air curtain and it should run in this set-up with no further adjustments,
automatically heating as required. If the target temperature is reached the air curtain
fans will still operate but the air stream is then not heated (ambient air curtain).
If the end user is to operate the air curtain with a PAR-31MAA Remote Controller, set
up the No.1 locking function on the controller so they can only switch the air curtain
ON or OFF, with no control of mode or target temperatures. See user instructions for
the Mitsubishi Electric PAR-31MAA Remote Controller.
If the air curtain is to be operated from a BMS System or Centralised Controller this
should be configured so that the air curtain can only operate in HEAT or FAN mode if it
