manufactured in accordance with the Pressure Equipment Directive and the installation
must be carried out to a good standard of workmanship. Remove the protective plastic
film on top of the air curtain before starting work. Use a heat sink on the copper pipes
when brazing to reduce the transfer of heat to the inside of the air curtain where
sensitive components are located.
To gain access inside the Air Curtain
To gain access for connection of the electrical supply, controls
wiring and to work on the unit during commissioning, remove the
air inlet grilles and the bottom access panel.
First remove the plastic end caps if already fitted by pulling off to
the side (see picture).
Then remove each inlet grille in turn with its filter by unfastening
the M4 Pozi Head screw at the bottom corner of the grille. Use a
Pozi No.1 screwdriver to access the screw via the elongated
hole at each bottom corner of the grille (see adjacent picture).
To remove the bottom access panel unfasten the access panel
securing screws, one at each end and two in the centre
(PHV1500 and PHV2000 units) and slide the panel out forwards.
Please note: All the panels of the air curtain are covered in a
protective plastic film which should be removed.
Electrical Supply to the Air Curtain
This must be carried out AFTER the connection of the refrigerant pipework. All
electrical wiring and connections MUST be carried out by a competent qualified
electrician in accordance with the latest edition of the IEE wiring regulations
and/or local statutory regulations. (see also Wiring Diagram on Page 10)

defrost electric heaters are required.
•
The appliance must be connected using cables having an appropriate temperature
rating (heat resistant).
•
Ensure that the supply cables, circuit breakers and other electrical installation
equipment are correctly sized for the air curtain being installed. See Table
