Product and Safety Information Following terms are used throughout this manual to bring attention to the presence of potential hazards or to important information concerning the product. CAUTION DANGER Indicates a potentially hazardous situation which, if ignored, may result in minor injury or property damage. WARNING Indicates special instructions on installation, operation, or maintenance, which are important to equipment but not related to personal injury hazards.
general Product Information HIgH EffICIEnCy aPPlICaTIonS The design of the plates creates two separate channels for a true counter current flow movement. This complex channel system results in high turbulence and high heat transfer. TTP Braze Plate Heat Exchangers are suitable for a variety of single-phase fluid-to-fluid and two-phase refrigerant to fluid applications.
operation and Code restrictions ProduCT aPProvalS WaTEr / fluId QualITy rESTrICTIonS - • - Triangle Tube’s TTP Braze Plate Heat Exchangers are UL approved. • ASME is available as an option. • CodE CoMPlIanCE & rESTrICTIonS • • • All piping and installations must conform with the instructions listed in this manual and where applicable: - • Local, state, provincial and national codes.
general Installation MounTIng guIdElInES gEnEral InSTallaTIon rEQuIrEMEnTS - Ensure all plumbing / piping meets or exceeds all local, state or national codes. - Install unions for easy removal of the braze plate heat exchanger. It is recommended to use dielectric unions or couplings to protect fittings from corrosion when connecting dissimilar materials such as copper and galvanized iron pipe.

general Installation WARNING WARNING do not braze the heat exchanger in a horizontal or flat position. Solder material may fall into the heat exchanger or piping connection, creating a blockage within the distribution channels . direct the flame away from the heat exchanger do not heat the welding area higher than 1200ºf. damage to the heat exchanger brazing material could occur. fig. 5: Welded Connection THrEadEd ConnECTIonS fig. 4: Solder Connection General Guidelines • WEldIng ProCEdurES 1.
Maintenance and Cleaning WARNING gEnEral guIdElInES for ClEanIng • • • • To prevent damage to the heat exchanger and refrigerant components, do not chemically clean the refrigerant circuit of the heat exchanger. A 5% solution of Phosphoric Acid or Oxalic Acid is recommended as a cleaning solution. Other types of cleaning solutions such as ice making machine de-scaler are available and may be used, check the manufacturer’s instructions for compatability.
applicatons doMESTIC WaTEr aPPlICaTIonS • Typically the fluid circuit with the highest temperature and/or pressure should be connected to the left side connections as indicated with the colored label. • Primary Supply The circuit flows should be piped in a counterflow arrangement. • Domestic Inlet Primary Return On instantenous water heating applications (applications without any storage tank) a flow switch must be used to prevent overheating of the heat exchanger.
