TUBING CONNECTIONS AT POWER UNIT
This section refers to Figure 29.
Your power unit is capable of being connected to the intake
vacuum trunk line from either side. Select the intake
connection to be used. Some installations may require the
connection into both intakes. The power unit has 4 intake
connections, which 2 of them are factory sealed.
1. Using provided coupling (part no. V127),
attach the utility valve assembly to 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 plastic cap provided.
3. If vented to the outside, attach exhaust tube to power unit
using provided coupling (part no. V127).
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 V142 wall caps.

Grounding Instructions – This appliance must be grounded.
If it should malfunction or break down, grounding provides a
path of least resistance for electric current, to reduce the risk
of electric shock. This appliance is equipped with a cord
having an equipment-grounding conductor and grounding
plug. The plug must be plugged into an appropriate outlet that
is properly installed and grounded in accordance with all local
codes and ordinances.
Broan VX3000C & VX6000C and NuTone VX475CC &
VX550CC are for use on a standard 120 VAC, dedicated
15-amp branch circuit with a NEMA 5-15R receptacle or a
dedicated 20-amp branch circuit with a NEMA 5-20R receptacle.
For Broan VX12000C and NuTone VX1040CC power units, a
nominal 240 VAC, dedicated 20-amp branch circuit with
NEMA 6-20R receptacle is required. Make sure that the appliance
is connected to an outlet and has a grounding attachment
plug that looks like the plug shown in either Figure 30 or 31
(on page 20) depending on model. No adapter should be
used with this appliance.
