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", Page 33.
If the air curtain is to be operated under manual control using a PAR-31MAA or PAR-
U02MEDA remote controller, it is important that 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.
Explain how the fan speeds operate, whether this is manual 3-speed fan control using a
PAR-31MAA or PAR-U02MEDA remote controller, or if there is a door operated switch
that switches fan speeds to High – Door open, or Low – Door closed.
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/AUTO mode operates.
Leave the system set to HEAT and lock all buttons on the remote controller except the
ON/OFF button before leaving site (Locking Function No.1).
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 or AUTO 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.
