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 now 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 Diagrams on Pages 14 and 15) 

 

 

A local isolator having a contact separation of at least 3mm on all poles must be 
fitted in the electrical supply to the air curtain and located in an accessible position 
adjacent to the unit. 3 phase if defrost electric heaters are required. 1 phase if 
defrost electric heaters are not 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 below. 

 

A 20mm size cable gland or conduit connector should be used for the Electrical 
Supply into the air curtain. 

 

This appliance must be Earthed.
