Repressurizing Potterton Puma 100e - HELP

[ggggg1]

Hi,

I've got a Potterton Puma 100e boiler with a flexible hose filling loop.

My boiler has low pressure in the system.
I checked the online on how to do it and from this link: http://www.heateam.co.uk/docs/How-to-repressurise-your-boiler-using-a-Flexible-Hose-Filling-Loop.pdf it looks easy-peasy.

Only problem is that my boiler has no taps!

Here are two pics of my tapless boiler:

Do I need to turn the nut and screw up/downstream of the flexible hose?

Anyone have any idea on how to repressurize my boiler?

THANKS!!

G.

With a flat-headed screwdriver, carefully turn the slot in the valve in your 2nd picture. Slowly re-pressurise to 1 bar (system cold) and turn back to its original position.
