Preparation
5.1.
Assembling the PRV (Pressure Relief
Valve)
Step 1.
Ensure you have these three items and
lay them on a clear space.
Step 2.
Unscrew the lid completely and remove
from the valve. Note the small ring and
large ring (indent side on spring side)
positions.
Step 3.
Place the forceps between the small and
large plastic rings, use leverage to pry the
small ring off. Remove the large ring and
the cone shaped spring. Do not grasp the
plastic rings with the forceps as ring
damage can occur.
Step 4.
Place the small and large rings on a level
surface.
Step 5.
Remove and re-insert the cone shaped
spring, wide side at bottom.
Step 6.
Place the large (indented side on spring
side) and small rings back onto the stem.
Step 7.
Put on the marking collar with flat side at
bottom.
Step 8.
Screw on the lid (hand-tight) and place
the newly built PRV aside, ready to
assemble with the Ventilation Circuit.
