WP-35  35A Fan / Water Pump Control Kit

 

Installation

Setting the Jumpers

Temperature

The Delta controller is factory set to operate with a 180° thermostat, the unit temperature can be adjusted byway of jumpers. Jumpers (5,7) and (6,8) raise the temperature by 22° and 14° respectively. Jumpers (7,9) and (8,10) lower the temperature by 22° and 14° respectively. The chart in figure 2 shows jumper settings for various temperatures.

Underdrive

Connect the provided jumper(13,14) to render a 10 % minimum current to the fan and water pump whenever the ignition is on in order to provide a nominal flow. The ignition input wire must be connected to use this feature.

Mounting the control unit

Find a flat surface in the engine compartment, the preferred area being the radiator support sheet metal near the battery. Drill four 1/8" holes either by the dimensions shown in figure 2 or by using the control unit as a template. Drill two more 1/8" holes at about 8" centers as shown in figure 2. If installed in a detailed engine compartment, insert the four grommets in the mounting holes of the control unit to protect painted surfaces. Mount the control unit using four self tapping screws and flat washers.

 

Delta fast response temperature sensor

Mounting the temperature sensor

Figure 1a shows the Delta temperature probe. Figure 1b shows the typical mounting on the thermostat housing. Note that on engines with the thermostat on the engine coolant intake, the probe must be mounted near the outgoing engine (hot side) coolant.

Control unit wiring

High current wiring

  1. Plug the mounted sensor into pins 1, 2 of the control unit.

  2. Using the supplied wiring loom, secure one connectored end of the red wire on the output terminal of the controller using one star washer and a brass 6-32 hex nut. A snug fit is all that is needed (5-in-lb), Be careful not to overtighten. Route the wire to the positive fan terminal, cut and trim the wire and install the female fastconnect harness. If needed, install the male fastconnects to the fan and water pump input wires.

  3. Place one connectored end of the black wire on the GND terminal of the controller. Route the wire to the negative fan terminal, cut and trim the wire and install the female fastconnect harness. Connect the fan and water pump.

  4. Place the connectored end of the remaining black wire on the GND terminal of the controller and secure both wires with one star washer and 6-32 brass hex nut. Route the wire to the negative battery terminal. Attach the 5/16 ring terminal and connect to the negative battery terminal.

  5. Place the connectored end of the remaining red wire on the input terminal of the controller and secure the wire with one star washer and a brass 6-32 hex nut. Route the wire to the positive battery terminal. Attach the fusible link and connect to the positive battery terminal. Do not connect to the starter end of the battery cable or to the alternator. Use the supplied wire hold downs, along with two self tapping screws and flat washers to secure the wires.

CAUTION

INSERTING A JUMPER ACROSS PINS 11 and 12 WILL DAMAGE THE CONTROL UNIT

 

Auxiliary wiring
Ignition input
Connect the yellow ignition input wire of the harness to the unit and to any source that is higher than 6 V whenever the ignition is on.


AC input
If the vehicle has air conditioning and a factory installed electric fan, connect the blue AC input wire of the harness to the unit and to the positive terminal of the OEM fan wiring harness. If the vehicle has air conditioning and originally came with a mechanical fan, connect the blue AC input wire of the harness to the air conditioning compressor input.

Testing the unit

Start the car. If equipped with air conditioning, turn on the AC, the fan should run at 100%. Check the direction of air and coolant flow and reverse the fan and water pump input wires if necessary. Turn off the AC and let the engine warm up. The fan and water pump should run at the necessary speed to stabilize engine temperature.
