Product Labelling

All Price SPV8000 units are tagged with

a control assembly label as shown on
the right. This label identifies the model
number, size, location, controller type,
application and controller setpoints for
the unit. The label can be found on the
control side of the terminal unit.

All controllers are tagged with a controller

label as shown. The label identifies the
required sensor velocity pressure for
both minimum and maximum flow
setpoints.

Actuator Mounting Instructions

The SPV 8000 has been designed to accommodate several manu-

facturers' actuators for both normally open or normally closed
fail-safe operation.

Figure 1 illustrates the standard actuator and linkage orientation

for normally open units. Figure 2 illustrates the orientation of a
normally closed unit.

If relocation of the actuator becomes necessary due to a change in

required damper fail-safe position from normally open to normally
closed or vice versa, the following procedure should be used: Figure 1
Normally Open configuration
1. Loosen the crank arm bolt (A) until the damper shaft rotates (Righthand Control only)
freely.

2. Remove the screws (B) securing the actuator mounting bracket

to the base.

3. Relocate the actuator to the proper mounting holes as per

Figure 3 and Table 1.

4. Insure the actuator linkage is in the proper orientation as

per Figure 1 or Figure 2. Install screws (B) securing actuator
mounting bracket to the terminal.

5. Rotate the damper shaft until the damper is in the fail-safe

posi­­tion (full open or full closed) and tighten bolt on the crank Figure 2

Troubleshooting Guide
General 1. Locate thermostat and cycle — direct acting stat will bleed on
heating.
2. Confirm box size and rating with drawing and box schedule
(check label on terminal). Check position of controller to ensure
it is installed level.
3. For CP101 controller, check the damper selector switch at the
face of the controller. Ensure that switch is set in the correct
mode.
4. Visually check piping and connections to box controls and
motor.
Blue — Main Air (M)
White — Thermostat (T)
Yellow — Actuator (B)
Red — High Port (X - CP100) (Y - CP200)
(H - CP101)
Green — Low Port (Y - CP100) (X - CP200)
(L - CP101)
5. Confirm caps are securely in place on the tees in the sensor
lines between the sensor and the controller.
6. Confirm that the "G" port cap on controller is in place.
7. Confirm main air pressure (15 psi minimum - 25 psi
maximum).
8. Confirm thermostat pressure. Cycle thermostat from full
cooling to full heating.
9. Confirm actuator pressure from controller by cycling
thermostat.
10. Confirm actuator operation by stroking actuator with a hand
pump noting at what pressure the actuator begins to stroke
and is fully stroked.

If Velocity Pressure is Below Specified Value 1. Connect a differential pressure gauge (0 - 1.0" w.g.) to the tees
and the Damper is Fully Open in the sensor lines between the sensor and the controller.
2. Check velocity pressure reading and compare with the value
indicated on the controller label.
3. If the velocity pressure is below the specified value and the
damper is fully open, this would indicate insufficient inlet duct
static pressure, starving.

If the Velocity Pressure Indicated by the 1. If the damper of the control assembly is partially closed, this
indicates the unit is under control.
Gauge Does Not Match the Specified Value.
2. If the velocity pressure indicated by the gauge does not match
the specified value, recalibrate the controller according to the
procedures outlined in this manual.
