DOLLY – TANK ASSEMBLY
For compact drive unit model see Section S.
1.
The Dolly/Tank has a pre-cut hole over the drive port. Insert the drive/bag Interface
into this hole from below and apply the O-ring to secure as shown in Figure 5. It is not
necessary to remove or replace the Interface after installation (i.e. after mixing or
between batches).
2.
Position the plastic tank on the dolly. The bottom of the tank has two pre-cut holes: a
small hole for the bag drain and a larger hole for the drive head. Line up the larger hole
with the drive port on the dolly. The tank hole should fit loosely around the Interface.
3.
When using PALL standard containers and dollies, tanks up to and including 350L use a
centrally located impeller and therefore use the central port dolly configuration. PALL
standard 500L bags use off-center impeller and therefore use the off-center port dolly
configuration.
See procedure below for changing the dolly port configuration.
CHANGING DOLLY CONFIGURATION BETWEEN CENTER AND OFF-CENTER IMPELLER PORT
1.
Determine which port configuration is required: central 15” port or off-center 8” port.
Each rail of the dual port has an adjuster attached to the rail with two screws. The right
adjuster is marked with two dots and the left adjuster is marked with one dot. The right
and left rails of the port are also marked with two and one dot respectively,
see images
below
. Right adjuster should always be used with the right rail and the left adjuster with
the left rail.
