A two speed motor will typically be prefitted with four short wires which must be connected to the swamp cooler control circuit and the 120 volt circuit.

Two speed swamp cooler motor wiring.

6 position wall switch for 2 speed evaporative coolers to control high and low speeds a qualified electrician should check all wiring and circuit motor and pump voltage and amperage must not. Fix the connecting nuts with the wire pliers. Step 2 run romex cable. Both of these simply plug into the wall and utilize the provided switch on the front of the discharge grille.

Since a two speed motor relies on different coils to produce different speeds there are usually two input wires. Take the romex cable and guide it from the electric makeup box of the swamp cooler to the electric panel box with the breakers. When voltage is applied to the high side the windings in the motor will turn it faster. Solder all connections and use a shrink wrap insulation kit to seal the connections.

The durable steel motor can be used in a new cooler or as a replacement motor for an existing unit. In many instances the low and high speed coils share an external wire. It s built for reliable long life performance. If your swamp cooler only has one fan speed wire the fan to terminal 1 the black wire operates the motor s high speed.

When voltage is applied to the low side the windings in the motor it will turn the motor slower. Then plug the box connector in the hole. Hi on these evaporative water coolers you would have to take a look at you may have had a 1 2 h p. Motor on the old one and the new one.

Pmi s 3 4 hp 120 volt 2 speed evaporative cooler motor pmi s 3 4 hp 120 volt 2 speed evaporative cooler motor has such stringent performance requirements that it holds a strong 3 year warranty. Here is a swamp cooler blower motor with the leads for hi low and common labeled h l and c. The swamp cooler wiring pictured and explained here is unnecessary if you are installing a window mount cooler or a sidedraft style window cooler. A six position rotary switch has a position for off low speed fan high speed fan low speed fan with pump high speed fan with pump and pump only.

If there is a hole blank in the panel remove it with the screwdriver and or the pliers. 2 speed 3 4 hp evaporative cooler motor the dial 3 4 hp evaporative cooler motor the dial 3 4 hp evaporative cooler motor is built for reliable performance in 115 volt evaporative coolers.
