3.5 Installation of the OPT IQ BNA
This section describes the two procedures to be followed for the safe installation of the
Crypto BNA terminal:
• Procedure for installation of the ground frame in the concrete floor (refer to section 3.5.1)
• Procedure for the lifting and placement of the BNA terminal (refer to section 3.5.2)
Important Installation Notes/Remarks
The Crypto BNA must be installed at least 20 cm from the dispenser.
The Crypto BNA must be installed at least 2 metres from the ground-tank air outlet.
Ensure that the base of the BNA is closed in order to prevent the ‘chimney’ effect i.e. when
vapour is sucked through an electrical wiring pipe into the BNA terminal causing a
potentially hazardous situation.
Weight of the complete Crypto BNA terminal is 225 kg. Refer to Figure 5 for the dimensions.
Part number of the lifting device is 907389.
3.5.1 GROUND FRAME INSTALLATION PROCEDURE
When working on the site, ensure that the general safety procedures are followed.
INSTRUCTIONS:
1) The ground frame is delivered together with the Crypto BNA housing (Fig 1).
2) Locate the ground frame in the concrete as shown in Fig 2.
3) Locate the pipe for the electrical wiring cables in the centre of the ground frame.
4) Ensure the ground frame is positioned completely horizontal.
5) Ensure the ground frame upper plate is positioned just above the concrete.
