6.1 Unpacking the pressure balance
As soon as possible after delivery open the packaging of the system and check that
you have all the items detailed in the packing list (see chapter 4.2 “Scope of delivery”).
As you are unpacking the items, examine them for signs of damage or breakage during
transit.
If any items are missing get in touch immediately with DH-Budenberg/WIKA to inform us
of the shortage.
6.2 Environmental requirement
When siting the pressure balance if not in a temperature controlled laboratory look for
an area that satisfies the following criteria as much as possible:
■ A constant temperature area free from draughts and sources of heat or cold
■ An area free from noise and vibration, constantly used pathways
■ A clean dry area free from corrosive liquids or vapours
A strong, stable, level table or workbench with the capability of supporting the system
with sufficient space to operate is required.
6.3 Assembly of base units
Fastening base to bench
The base is to be mounted on a firm, level table or bench about 0.9 m high. The centre
line of the front adjustable feet of the unit should be about 40 mm from the front edge of
the bench to allow adequate clearance for the handwheel.
1. Mark the position of the adjustable feet of the unit on the top of the bench.
2. Position a level plate at the centre of each of the adjustable feet of the unit and screw
the plate to the bench to ensure that the pressure balance is rigid.
3. Fit the base unit on the bench with the adjustable feet on the level plates and the
handwheel shaft projecting over the front of the bench.
4. Screw in the four handwheel spokes into the hub.
5. Using the spirit level provided, level the unit in both the front/rear axis and the side
to side axis by adjusting the four knurled feet, by placing the spirit level on top of the
piston-cylinder unit.
