The following two instruments should be used in conjunction with the
PANDA unit:
TA465-P Multi-
function Instrument
Refer to TA465 Operation and
Service Manual supplied with the
instrument for additional parts
supplied as standard.
PVM620
Micromanometer
Refer to PVM620 Operation and
Service Manual supplied with the
instrument for additional parts
supplied as standard.
IMPORTANT—
Read Before Using the PANDA for the First Time
It is IMPORTANT that the PANDA be connected to the power supply
using a 30 mA residual-current device (RCD) or Ground Fault Circuit
Interrupter (GFCI).
It is IMPORTANT that the 110V PANDA (yellow power socket) be
connected only to 110V to 120V supplies. Connecting it to a higher
voltage supply will permanently damage the inverter.
The 220V/240V PANDA (blue power socket) should only be
connected to 200V to 240V power supplies.
When storing the PANDA in a vertical position, please ensure that the
straps holding the instrument box are in place and tightened first.
The PANDA is designed so that the instrument box and duct carry
tube are removable to lighten the load when lifting.
DANGER
Turn the isolation switch to the OFF position and wait 10 minutes
prior to disconnecting power.

Chapter 2
Preparing PAN300 System for Air Duct Leak
Testing
The following procedure should be followed carefully so that safe and
accurate leakage testing can be achieved:
Successfully completing a duct leakage test requires certain
information be compiled prior to starting the test. Refer to
Appendix B for a discussion of standards relating to duct
leakage testing. The list below indicates the information
required:
•Type of leakage test to be performed (Positive or
negative).
•Leakage standard to be followed.
•Air tightness/leakage class to be achieved
•Amount of ductwork to be tested, such as the complete
system or a statistical sample.
1. Select the section of the ductwork to be tested.
2. Calculate the surface area of the ductwork of the section to
be tested.
3. Temporarily seal the all openings of the ductwork except one,
which will be connected to the PAN300 duct leakage tester.
4. Position the PAN300 unit as close to the remaining opening in the
ductwork as possible to minimize the flexible tubing needed.
Minimize bends in the flexible tubing to reduce the pressure loss,
giving the best performance.
5. Make sure the Fan Control Switch on the Fan Speed Controller is
in the OFF position and the multi-turn Fan Speed Control
potentiometer is fully turned counter-clockwise using the pictures
of the VFD in Figure 1 as a reference. Plug the cord into the
PANDA unit as shown in Figure 2 and Figure 3. Then connect the
other end of the cord to a suitable electrical supply.

6 Chapter 2
CAUTION
Remove the power cord from the PANDA duct leakage tester
before tilting it to the vertical position to avoid damaging the cord.

6. Fit the primary duct adapter
spigot (black sheet metal
with rubber bung) to one end
of the 4-in. (100-mm)
diameter flexi-tube. Make an
air-tight seal using one of the
over lock straps and lever-
locking cam provided as
shown in Figure 4. Adjust
the fit of the over lock strap
with a screwdriver.
7. Securely attach the black
primary duct adapter
spigot/flexi-tube assembly to
the opening on the ductwork
to be pressure tested.
Figure 4. Flex Ductwork

Spigot. Bung not shown.
8. If the static pressure tap on
the black Primary Duct
Adapter is open to the duct,
connect the 16-ft (5-m) long
blue silicone tube to it as
shown in Figure 5.
If the static pressure tap on
the black Primary Duct
Adapter is not open to the
duct, drill a 4-mm hole in the
duct and insert about 6
inches (10 mm) of the
silicone tube into the duct.
Seal around the hole
with putty.

the cam lock connector (grey cast aluminum without nozzle).
Make an airtight seal using the other over lock strap and lever-
locking cam provided. Adjust the fit of the over lock strap with
a screwdriver.
10. Determine if you are going to perform a high- or low-flow testing
and positive or negative testing. Set-up the duct leakage
tester by:

8 Chapter 2
a. For positive pressure,
high-flow testing,
remove the low flow
nozzle if it is installed.
Then, connect the grey
cast-aluminum cam
lock connector to the
outlet side of the
blower per Figure 6.
Close both cam lock
arms at the same time
to ensure proper fit.
Connect the free end of
the 16-ft (5-m) silicone
Figure 6. Positive Pressure,
High-Flow Set-Up
tube to the pressure tap marked DUCT PRESSURE P3 (+)
on the black square box.
Finally, verify that the FLOW GRID MODE pressure taps on
the inlet tubes are connected to the FLOW GRID pressure
taps, i.e., P1 (+) to P1 (+) and P2 (-) to P2 (-).
b. For positive pressure,
low-flow testing, add
the low-flow nozzle to
the blower inlet if it is
not installed per
Figure 7. Then,
connect the grey cast-
aluminum cam lock
connector to the outlet
side of the blower per
Figure 6. Close both
cam lock arms at the
same time to ensure
proper fit.

Chapter 3
Performing a Duct Leakage Test
The PAN300 duct leakage test system includes a Model PVM620
Micromanometer and a Model TA465-P Ventilation Meter. During duct
leakage testing, the Model PVM620 Micromanometer measures the
duct static pressure while the Model TA465-P Ventilation Meter
measures the airflow rate.
Refer to the Operation and Service Manuals for the Model PVM620
Micromanometer and the Model TA465-P Ventilation Meter to use
these instruments in other applications. If you do not have the
manuals, download them from TSI®Incorporated’s website
www.tsi.com.
Measuring Duct Static Pressure
1. Turn ON the Model PVM620.
2. Zero the Model PVM620 pressure sensor with both ports open to
the atmosphere.
3. Connect the (+) port on the Model PVM620 to P3 (+) to measure
the duct static pressure (see Figure 6).
4. Leave the (-) port on the Model PVM620 open to the atmosphere.
NOTE
Refer to the Model PVM620 Operation and Service Manual for
instructions on using data logging to automatically record the duct
static pressure.

Measuring Duct Leakage Flow
Turning on the PAN300 Duct Leakage Tester
1. Switch the PANDA unit on.
a. For 230V models position the Mains Power switch of the
inverter to the ON position to power the Inverter speed
controller. The Fan motor is not energized.
b. 110V models DO NOT include a separate power switch. The
PANDA unit is turned on when the power cord is plugged in.
2. Position the Fan Control switch to the RUN position to energize
the fan.
3. Increase the fan to the desired speed by turning the Fan Speed
Controller clockwise. To decrease the fan speed, turn the Fan
Speed controller counter-clockwise.
1. Turn ON Model TA465-P.
2. Zero the Model TA465-P
pressure sensor with both
ports open to the
atmosphere.
3. Connect the Model TA465-P
to the PAN300 by connecting
the (+) and (-) ports on the
Model TA465-P to the P1 (+)
and P2 (+) ports located
inside the black box of the
PAN300 as shown in
Figure 10.
