odors and insects from entering the room even when there is no sealing water. And as our 30 years of experience shows, all of our products have excellent durability, easy maintenance, inspection, and cleaning, and look great.Odor Prevention The use of a check valve (Special floatball) and floating valve prevents backflow and bad odors.FRP does not rust. Therefore, you don’t need to worry about corrosion on the inside or outside. Also, condensation does not form easily on it. Main Unit Materials are FRP Due to the lightweight and floor installation type construction, it is easy to carry in, set, and install.Work efficiency Easy maintenance, inspec tion and cleaning through the top cap, trap cap, and float valve chest cap.Maintenance,Inspection, Cleaning A Trap types and selection flow There are basically 2 types of A Trap, the <Suction Type> and < Pressurized Type>, and you can select the type required according to the type of air conditioner (negative pressure/positive pressure) used. In particular, if you need to implement counter measures against condensation, we recommend you select the <heat insulation type>, which is the A trap unit that has been fittedwith insulating material. 3 different sizes of connecting diameter are available. There are further 3 additional custom made products available.Selection Conditions A Trap Variations Types of A Trap Suction Type <S Type> Suction Insulated Type <SW Type> Pressurized Type <P Type> Pressurized Insulated Type <PW Type> Air Conditioner Type Condensation Counter Measures Negative Pressure Positive Pressure Flow Inlet/Flow Outlet Socket Size Custom Products Not Required Required Not Required Required 3 Types of Connecting Pipe Size Transparent Cap Specifications Acrylic cap enabling you to see inside Heat Resistance Specifications (Max 80°C) Support for high temperature drainage water by changing the trap material Water Drainage Pipe Connector Specifications The main unit side is equipped with a connector for a water drainage pipe SUS Specifications Main unit constructed of stainless steel 32A 40A 50A This diagram is an example of installation when the main unit side is equipped with a chilled water coil drainage pipe/hot water coil drainage pipe connector (order made) The two checking functions of the non return valve (special floatball) and float valve operate to prevent odors and insects from entering the room, even if the sealing water has evaporated.Positive pressure in the air conditioner up to an equivalent of 1,470pa (150mmAq) is supported, preventing blow back. *When installing the suction type <S Type>, find the h dimension from the performance curve that corresponds to the internal static pressure of the air conditioner, and install it at a height greater than h.*1) When finding the h dimension for the suction insulated type <SW>, add 10mm to the value obtained from the graph. *2)When starting operation of the air conditioner, always fill the main unit to the flow outlet side section top with water.

A Trap External Dimensions Cautions for Installation and Handling of “A Trap”[Law for Maintenance of Sanitation in Buildings (Common name: Building Sanitation Law or Building Maintenance Law)] (Ministry of Health, Labour and Welfare)Points of Amendments and Counter Measures Both the A Trap and C trap are designed to effectively prevent infestations of mice, insects, and pathogens, bad odors, and the transmission of air borne infections via air conditioner drainage pipes, and are constructed for easy maintenance. The development and manufacture of all our products conform to Japanese laws, ordinances, and regulations.The importance of maintaining a sanitary environment for the drainage system of air conditioners was strengthened in the 2002 Ministry of Health, Labour and Welfare reforms of the “Law for Maintenance of Sani tation in Buildings (Common name: Building Sanitation Law or Building Maintenance Law)”. *For details, see the “Legal Guide” on page 6.Due to obligations outlined in the 2003 amendments to the Building Stan dards Act, in the background of the development of high performance air filters, awareness of the importance of the air quality is being improved.We believe the installation of the drain trap for air conditioning units is just one of continuing efforts to achieve better air quality.Floatball Drain Trap Series for Air Conditioning UnitsIn addition to the outstanding air backflow prevention performance of the logical floatball system, the drain traps are both easy to install, and easy to inspect and clean.The drainage pipes on an air conditioning unit are connected to the draining basin in order to drain condensation that occurs when running in cooling mode. However, dirty air in the atmosphere also flows through the drainage pipes from the breather inlet. In order to protect the quality of air inside the room, it is important to prevent odors and insects from entering the room from the drainage pipe. Drain trap for medium/large sized air conditioners.

Floatball type drain trap for small air conditioners Multi-use compact trap At present, there are many small type individual room air condi-tioners that are not equipped to prevent the backflow of air from the drainage pipes. You can prevent the backflow of air and therefore the inclusion of dirty air by installing the “C Trap” to each individual air conditioner. Additionally, you can also use the C Trap for many other purposes, such as a trap for the drainage water from automatic air extraction valves or expan-sion tanks for electric water heaters.Special floatball effectively prevents the backflow of dirty air even if the sealing water evapo-rates Outstanding odor prevention and insect prevention Super-compact design makes it perfect as a drainage trap for small air conditioners Internal parts can be installed and removed easily, making inspections and cleaning easy too Easy inspection of concealed sections thanks to reflective tape Horizontal Installation Type Main Applications Drain trap for air conditioners Fan coil units Building multiple air conditioners (indoor equipment)Small floor installed package air conditioners (indoor equipment) Other small air conditioners Expansion tank drainage water trap for electric water heaters, “Ecocute” etc. Drainage water trap for latent heat collection gas water heaters Drainage water trap for refrigerators and chilled showcases Drainage water trap for ice machine Drainage water trap for automatic air release valve You do not need to install a U trap or other such device at the end of the drainage pipe.Cautions for installation and handling of C Trap Make sure you fully read through the instruction manual included with the product before installation, and make sure you use the product correctly. When connecting this product, make sure that a double-trap is not formed. For medium and large sized air conditioners, use the A Trap. Be careful not to confuse similar products or products with similar names.Example of connection to a small air conditioner drain pipe The difference H is required depending on the internal static pressure of the connected air conditioner. H(mm)=X(Pa)÷9.8(Example) When the internal static pressure: -294Pa 294(Pa)÷9.8=30(mmAq) →Therefore, the difference H must be greater than 30mm.Scope of Use : Internal static pressure: 0~-500pa Connection method for connection to drain up mechanism air conditioner Correct Connection Method When connecting the C Trap to a drain up mechanism pipe, connect to the horizontal pipe when the reversed U shaped pipes are pointing downwards.
