airflow. If a field-provided K-factor is to be used (see
below), the measured airflow for the system should be
divided by the number of active fans to get a single-fan
K-factor.
Field-obtained factors can provide maximum accuracy. To
obtain the factor in the field, measure the differential
pressure output from the transmitter while measuring the
airflow through the system. Once these two values have
been measured, simply solve for K using the following
equation:
K = ACFM/SQRT(DP)
Where:
K = Field-provided constant factor.
ACFM = Actual airflow (ft
the air density being measured.
DP = Differential pressure (inches w.g.) being
measured by the transmitter.

Maintenance

For a typical HVAC environment - especially with upstream
filtration - there should be little to no required
maintenance. In extreme cases or for mishaps (bearing
grease in the taps for example), the flow meter is easily
cleanable. The fan inlet airflow measuring system is
extremely simple: a few pressure taps, a few fittings, and
some tubing. Although unlikely, if any tap were to get
clogged, simply disconnect each side of the transmitter
and blast air in a reverse direction through the system.

Energy Wheel Startup

WARNING
Toxic Hazards with Exhaust Air!
Do not use an energy wheel in an application where the
exhaust air is contaminated with harmful toxins or
biohazards. Using an energy wheel could displace vast
quantity of contaminated air which could result in
asphyxiation and poisoning. Failure to follow this
instruction could result in death or serious injury.
WARNING
Hazardous Voltage w/Capacitors!
Disconnect all electric power, including remote
disconnects and discharge all motor start/run
capacitors before servicing. Follow proper lockout/
tagout procedures to ensure the power cannot be
inadvertently energized. Verify with an appropriate
voltmeter that all capacitors have discharged. Failure to
disconnect power and discharge capacitors before
servicing could result in death or serious injury.
For additional information regarding the safe discharge
of capacitors, see PROD-SVB06A-EN
CLCH-SVX010A-EN

NOTICE:
Equipment Damage!
Exceeding the recommended airflow can result in
damage to equipment. Trane is not responsible for
equipment damage resulting from exceeding
recommendations.
Do not exceed the maximum rated airflow for the wheel.
The pressure drop across the wheel is not to exceed 1.25
inches w.g.
1. Set diameter seals. See
Adjustment, " p. 76.
2. Turn the energy wheel clockwise (as viewed from the
pulley side) by hand to verify that the wheel turns
freely through its full rotation.
3. Confirm that all wheel segments are fully engaged in
the wheel frame and that segment retainers are
completely fastened.
.
Figure 68. Completely fasten segment retainers
4. With hands and objects away from moving parts,
activate the wheel and confirm the wheel rotation. The
correct rotation direction is clockwise as viewed from
the pulley side.
5. Start and stop the wheel several times to confirm seal
adjustment and proper belt tracking on the wheel rim.
The correct belt tracking is approximately a quarter
inch from the outer edge of the rim.
