Application Examples
1) Vertical Multi-Zone Installation
The Tamas Z-Block can be installed in a vertical
Configuration. When installing multiple
Z-Block modules vertically, the optional Vent
Fitting (part # 025-0021) must be used for the
air vent or thermistor sensor. This fitting is a
1/8” MPT thread which can house any
manufacturers automatic or manual Air Vent.
When used for venting purposes, it is
required that the user drill a 5mm (0.2”)
hole in the bottom of the fitting. The user
must also drill a 5mm (0.2”) hole in the
bottom of the end cap that the fitting will
be installed in. (Refer to FIG 4. on page 5)
e.g. Vertical Installation with 180° End Connection (#025-0005), and
End Cap Vent Fitting.
180° End Connector
This component can be fitted
with a multitude of optional
accessories, such as Air Vents,
Thermistors and Purge Valves.
Drill 5mm (0.2”) hole
in bottom of fitting.

2) Injection Pump Installation
e.g. Horizontal Installation with Injection Pump and 180° End Connection
(#025-0005).
When using the Z-Block as an Injection Pump, connect the Z-Block
to the manifold in an inverted position. In this position, the Pump
Head (part #025-0010) will need to be inverted 180° as well. To
do this, remove the 4 pump bolts and turn the pump head to the
desired location. Replace the screws when finished. Do not spin
the pump base.
WARNING: Remove Sweat connections from Z-Block BEFORE
attempting to solder to them.
FIG 9.
Remove all 4 Pump
Bolts

Flip the Pump Head 180°, so that
the top faces away from the Au-
tovent. Bolt the Pump Head back
into place.
