AQ4 Installation instructions

2.5 Vent piping

1.Install 5" to 4" reducer pipe on top of the water heater and then connect a 4" 90º elbow to begin the horizontal run. Use 4” vent pipe to connect from this elbow to the power vent motor inlet, avoiding elbows when possible. The maximum vent length from the water heater to the point of termination is 25 feet with one elbow. (Fig. 5) If using more than one 90° elbow, subtract 5 feet off the maximum vent length for each additional elbow used. A maximum of three elbows is allowed. The minimum straight vent length is 2 ft.

2.Support the vent pipe in accordance with vent pipe manufacturer’s instructions. Vent pipe is not supplied in the power vent kit, with the exception of the 5" to 4" reducer in the AQ4 kit. Observe the clearances associated with the class of vent pipe used. 4" single wall galvanized, 4" stainless steel or 4" B-vent pipe is required.

2.6 Linear safety spillage switch

The linear safety spillage switch provides a means for safety shut down of the water heater in the event of flue blockage or power vent failure. If hot flue gases spill from the draft hood diverter, the draft spillage sensing switch will open the pilot safety circuit and shut off all gas to the water heater. The switch is normally closed and opens at temperatures greater than 185º F. It has a manual reset button.

Mounting the linear safety spillage switch

1.Attach the spillage switch to the top left of the heater’s draft diverter using the existing hole and the included mounting screw. (Fig. 6)

2.Lay copper capillary sensing tube across top of the draft diverter. Allow excess tube to hang down right side of heater. Do not cut or crimp capillary tube.

3.Route the two wires from the spillage switch down the left side of heater to the ECO keeping the cables out of contact with hot surfaces. (Fig. 6)

Connecting linear safety spillage switch to pilot safety circuit

The ECO/temperature limiter is mounted on the lower left outlet water pipe. (Fig. 7)

1.Remove one wire lead connected to ECO terminal (it does not matter which one is disconnected).

2.Attach ¼" quick connect terminal end of linear spill switch cable to now exposed terminal of the ECO.

3.Connect the male spade connector to the removed lead wire from step 1. See the wiring diagram in Fig. 13 to confirm proper set up.

AQ4 specifications

AquaStar AQ4 is a cutting-edge water filtration system designed to provide clean and safe drinking water for households and businesses. This innovative product stands out in the market with its advanced technology and user-friendly features, making it a top choice for those seeking high-quality water purification.

One of the main features of the AquaStar AQ4 is its multi-stage filtration process. The system employs a series of filters that work together to remove a wide range of contaminants from water. This includes sediment, chlorine, heavy metals, and microorganisms. The first stage is a sediment filter that captures larger particles, while subsequent filters target smaller impurities. This comprehensive approach ensures that the water is not only clear but also free from harmful substances.

The AquaStar AQ4 utilizes activated carbon technology, which is renowned for its effectiveness in removing odors and improving taste. The activated carbon filter absorbs chemicals and volatile organic compounds (VOCs), resulting in crisp and refreshing drinking water. Additionally, the system features a reverse osmosis membrane, which acts as a barrier, allowing only pure water molecules to pass through while blocking contaminants.

Another impressive characteristic of the AquaStar AQ4 is its smart monitoring system. It is equipped with sensors that track filter performance and water quality in real time. Users receive alerts when it is time to replace filters, ensuring optimal performance at all times. This intelligent feature not only simplifies maintenance but also enhances the longevity of the system.

Installation and operation of the AquaStar AQ4 are straightforward, catering to both DIY enthusiasts and those who prefer professional assistance. The compact design allows it to fit seamlessly under most kitchen sinks, saving valuable space. Moreover, the system operates quietly, making it suitable for residential or commercial use without causing disturbances.

In addition, the AquaStar AQ4 is environmentally friendly. By reducing the reliance on bottled water, it contributes to decreasing plastic waste. The system’s durable filters are designed to provide long-lasting performance, reducing the frequency of replacements and promoting sustainability.

In conclusion, the AquaStar AQ4 is a robust water filtration solution that combines advanced technology with user-friendly features. Its multi-stage filtration process, activated carbon technology, smart monitoring system, and environmental benefits make it an excellent choice for anyone seeking quality water purification. With the AquaStar AQ4, users can enjoy peace of mind knowing that they have access to safe and great-tasting water at all times.
