If the Air Curtain is set-up for :-

Inlet Air Temperature Control

Room Air Temperature Control

(air curtain has been modified during commissioning)

with a PAR-30MAA Remote Controller, BMS or Centralised Controller :-

Switch the Mode Button on the PAR-30MAA 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-30MAA 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 1 & 2 on Pages 16 and 17). There must also be a condensate

disposal system fitted.

To conserve energy and carbon resources it is recommended to set up the PAR-

30MAA 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-30MAA 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-30MAA Remote Controller.
