To access the Filter Indicator pcb to change jumper:-
Switch off the electrical power to the Heat Pump Air Curtain.
If the left-hand plastic end cap is already fitted, remove it
from the air curtain. Unfasten the two screws as indicated.
Gently lower the left-hand end of the outlet grille, supporting
it from below. The Filter Indicator pcb is now accessible to
change the jumper.
Once the filter indicator pcb ‘jumper’ has been re-positioned,
push the outlet grille back into place and fasten screws.
Hand-over to End-User
Before leaving site it is important that there is a 'Hand-Over Meeting' to hand-over the
heat pump system and air curtain installation to the end user or their representative.
This should include a full and clear explanation of how the system operates. Be sure to
explain the Filter Indicator Schedule, that the air inlet grilles must be regularly vacuum
cleaned and the unit serviced at regular intervals.
If the air curtain is to be operated under manual control, it is important that the end user
understands how the Mitsubishi Electric PAR-21MAA Remote Controller and 3-Speed
Fan Switch operate. That the PAR-21MAA Remote Controller has been locked so only
the ON/Off button functions and the air curtain operates in AUTO mode with a fixed
target temperature of 24°C. If a condensate pump and drain system has not been fitted
it is vital they understand that the air curtain must not be run in COOL or AUTO mode
and that the PAR-21MAA Remote Controller has been locked so only the ON/Off button
functions and the air curtain operates only in HEAT mode with a fixed target
temperature of 24°C.
If the air curtain is to be operated under the control of a BMS System or Centralised
Controller, explain all the settings and demonstrate the operation of the system. If a
condensate pump and drain system has not been fitted it is vital they understand that
the air curtain must not be run in COOL or AUTO mode, that it must only be operated in
HEAT or FAN mode.
If a condensate pump and drain system has been fitted and they are going to run the air
curtain in COOL mode (not just AUTO mode) explain that the target temperature should
be adjusted to a comfortable level of cooling, not necessarily to the lowest target
temperature possible as this uses a lot more energy and carbon resources.
Ensure that all instructions and manuals are handed to the end user or their
representative.
