Typical Dryer Boost Application

Dryer Boost Pressure

Sensing Kit (SDB110P)

for Installation Instructions

P/N 28131

Dryer Boost Pressure Sensing Kit includes:

• Air Pressure-Sensing Switch

• Probe

• Vinyl tubing

Dryer boosting involves adding an auxiliary fan (RB110) inline to a duct system to increase

airow and efciency of the system in installations having duct runs longer than specied

by the manufacturers of the primary heating, cooling or circulating device. Long duct runs

result in long drying times and excessive wear and tear on the dryer. Boosting is usually

required when the total duct length exceeds the following:

Using this Kit, the auxiliary fan is controlled

by an automatic pressure sensing switch as

shown in the drawing inset.

Dryer Boost Kit (SDP110P) Installation Instructions 5.0 Installation Troubleshooting If the auxillary fan fails to start when the device begins, check the following: Verify the AC voltage at the pressure switch. The pressure switch-point is approximately 0.1” WC. The device must generate this positive pressure to close the switch and start the auxillary fan. If not, check the probe and connecting tubing for blockage. You may blow gently into the tubing to check the switch operation.
