Final Check of the Unit
Replace the bottom access panel, air inlet grilles (with filters) and plastic end caps (see ‘To gain
access inside the Air Curtain’).
Power-up both the Outdoor Unit and the Air Curtain and re-check the operation of the unit.
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 and a demonstration showing
the air curtain running. Be sure to explain the Filter Indicator Schedule, that the air inlet grilles
and air filters must be regularly vacuum cleaned and the unit serviced at regular intervals. See
“Servicing the Air Curtain”.
If the air curtain is to be operated with
Weather Compensation Control (HEATING ECO
mode)
or
Discharge Air Temperature Control (HEATING mode)
using a PAR-W21MAA
remote controller:-
Make sure the end user understands how to select HEATING ECO mode and HEATING mode
and how the system will operate in each mode. Show the end user that by selecting HEATING
mode with the lowest target temperature (20°C) the air curtain can operate in FAN only
(Ambient) mode. Leave the system set to HEATING ECO to promote energy saving and lock
all buttons on the PAR-W21MAA remote controller except the ON/OFF button before leaving
site (Locking Function No.1).
If the air curtain is to be operated with
Inlet Air Temperature Control
or
Room Air
Temperature Control
using a PAR-31MAA remote controller:-
Make sure the end user understands how the heat pump system works. That the air curtain
operates in FAN (Ambient) mode or in HEAT mode with a fixed target temperature of, say,
24°C. If a condensate drain system has been installed and it is intended that the unit is to
operate in cooling mode, show the end user how the COOL mode operates. Leave the system
set to HEAT and lock all buttons on the PAR-31MAA remote controller except the ON/OFF
button before leaving site (Locking Function No.1).
Explain how the fan speeds operate if there is a door operated fan speed switch, remote 3-
speed fan switch or if the fan speed has been fixed.
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. That the air curtain should
be operated in FAN (Ambient) mode or in HEAT mode with a fixed target temperature of, say,
24°C. It is vital they understand that the air curtain must not be run in COOL mode if a
condensate drain system has not been installed.
If a condensate pump and drain system has been fitted and the air curtain is to be operated in
COOL 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 increases the carbon footprint.
Explain to the end user that the doorway should be closed whenever possible but that
during times of high pedestrian use it will become effectively ‘open doorway’. The air
curtain serves an essential purpose by saving energy and providing comfort to the
occupants when compared to an open doorway with no air curtain fitted.
Ensure that all instructions and manuals are handed to the end user or their representative.
