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 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-30MAA 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-
30MAA 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.
