INTRODUCTION
The Model 091-150 Auto Pump Timer limits the duty cycle of the Auto Pump to 1
hour on and 1 hour off. This is important to the life of the pump when it is
operating on a vehicle with an abnormally high leak. The unit prevents the pump
from operating at higher temperatures, and thus preserves the long life
characteristics of the pump.
INSTALLATION
1. Mount the unit using the two holes provided for this (see Figure 2)...
2. Open the Pressure Switch assembly (mounted on the Auto Pump), and
move the red wire running to the motor from the pressure switch to the
N.O. terminal on the timer as shown in Figure 1.
3. Connect a 14AWG wire to the “Com” terminal of the relay on the timer.
Use an un-insulated ¼” female quick disconnect.
4. Connect the other end of this wire to the open terminal on the pressure
switch – see Figure 1.
5. Check all wiring before proceeding
6. Close the Pressure Switch assembly.
7. The yellow LED on the Model 091-150 Auto Pump Timer, when lit,
indicates that the pump is in the “rest” portion of its cycle and the motor is
not running.
