TUBING CONNECTIONS AT
POWER UNIT
This section refers to Figures 53 and 54.
Your VX Series power units are capable of being
connected to the intake vacuum trunk line from either
side. Select the intake connection to be used. On some
installations, you may connect the vacuum air intake into
both intakes.
1. Using rubber coupling and hose clamp provided,
attach the utility valve assembly with the vacuum
trunk line feeding into the power unit. The utility valve
can be installed on the left or right hand side.
2. Cap off the unused intake tube with the red plastic
cap provided.
3. Attach exhaust tube to power unit using rubber
coupling and hose clamp provided (if vented to
the outside).
4. Make sure all tubing connections are air tight.
5. The exhaust should NOT be vented into a wall, ceiling
or concealed space in the house. It is recommended
to vent the vacuum exhaust air to the outside of the
house. Exterior vented exhaust lines should be
terminated using Model 393 wall caps or
CI330 wall caps.
