AquaStar 125B LPL, 125B NGL Open loop potable water and combination space heating system

Page 4

If you are using the AquaStar for combined space heating and potable water heating (see schematic diagram below), all piping and other components connected to the system must be suitable for potable water, (b) toxic chemicals such as those commonly used for boiler treatment to prevent corrosion and freezing must not be introduced into the system, and

(c)if the space heating requires water temperatures higher than those required for do- mestic, potable water, a mixing valve or other similar device must be provided to reduce scald hazard potential, (d) maximum system water temperature must not exceed 140°F

(60°C). DO NOT CONVERT AN EXISTING, CLOSED HOT WATER HEATING SYSTEM TO A COMBINATION SPACE AND POTABLE WATER HEATING SYSTEM USING THE AQUASTAR OR ANY OTHER HEAT SOURCE.

3. System shown is electric storage tank with recirculating supply drawn from the tapping for the lower heating element.

4. If circulation flow to the Aquastar 125BL is restricted, it may be necessary to adjust the temperature slide control to prevent overheating.

5. Schematic is for illustration and example only and must not be used for actual installation without appropriate engineering and technical advice from a professional properly licensed in the locality where the installation is made.

*Pipe PRV to appropriate discharge

**Tempering valve is required when tank water temperature is over 130 F.

GENERAL RULES TO FOLLOW

FOR SAFE OPERATION

1.You should follow these instructions when you install your heater. In the United States: The installation must conform with local codes or, in the absence of local codes, the National Fuel Gas Code ANSI Z223.1/NFPA 54.

In Canada: The Installation should conform with CGA B149.(1,2) INSTALLATION CODES and/or local installation codes.

2.Carefully plan where you install the heater. Correct combustion air supply and flue pipe installation are very important. If not installed correctly, fatal accidents can be caused by lack of air, carbon monoxide poisoning or fire.

3.The place where you install the heater must have enough ventilation. The National Fire Codes do not allow gas fired water heater installation in bathrooms, bedrooms or any

occupied rooms normally kept closed. See the section below on locating the heater.

4.You must vent your heater. See section on VENTING, Page 6.

5.The appliance must be disconnected from the gas supply piping system during any pressure testing at pressures in excess of 1/2 Psig (3.5 kPa).

The appliance must be isolated from the gas supply piping system by closing its individual manual shutoff valve during any pressure testing of the gas supply piping system at test pressures equal to or more than 1/2 Psig (3.5kPa). The appliance and its gas connection must be leak tested before placing the appliance in operation.

6.Keep water heater area clear and free from combustibles and flammable liquids. Do not locate the heater over any material which might burn.

125B NGL, 125B LPL specifications

The AquaStar 125B LPL and 125B NGL are innovative products designed to meet the growing demands of modern aquaculture and water treatment facilities. Equipped with advanced features and technologies, these models are engineered for efficiency, performance, and sustainability, making them essential tools for aquaculture professionals and facility managers alike.

One of the standout characteristics of the AquaStar 125B series is its enhanced filtration system. Both the LPL (Low Pressure Liquid) and NGL (Natural Gas Liquid) models incorporate a high-capacity filter that effectively removes particulate matter and impurities from water. This ensures higher water quality and promotes healthier aquatic life. The filtration system is designed for easy maintenance, allowing operators to perform routine cleanings without downtime.

In addition to filtration, the AquaStar 125B series boasts a state-of-the-art aeration system. Efficient oxygenation is crucial for aquatic organisms, and these models utilize fine bubble diffusers to maximize oxygen transfer rates. This technology not only ensures that fish and other aquatic species thrive but also minimizes energy consumption, ultimately reducing operational costs.

Both models feature robust, corrosion-resistant materials, enhancing their durability in challenging environments. The casing is designed to withstand exposure to wet and humid conditions, ensuring longevity and reliability in various operational scenarios. Furthermore, the AquaStar 125B series incorporates energy-efficient motors, promoting reduced power consumption and minimizing the environmental impact.

Another innovative aspect is the intelligent monitoring system integrated into both models. The digital interface provides real-time data on water quality parameters, such as pH levels, temperature, and dissolved oxygen content. This allows for proactive management and immediate adjustments when necessary, ensuring optimal conditions for aquatic life.

Safety is also a key consideration with the AquaStar 125B series. Both models feature built-in safety protocols, including automatic shutoff mechanisms and alerts for abnormal readings, further reinforcing their reliability in managing aquatic environments.

In summary, the AquaStar 125B LPL and 125B NGL represent a leap forward in aquaculture technology, combining advanced filtration, aeration systems, and smart monitoring features. Their durable design and energy efficiency make them suitable for both commercial and non-commercial applications. These models not only improve water quality but also enhance the overall productivity of aquaculture operations while being mindful of environmental sustainability.
