NSF Product and Service Listings

[1] Product trade names may contain the suffix "-SKID Emergency Water Heating Skid". This
    denotes the use of a skid.
    
    The 'D' in the trade name indicates a digital control. VAC can be 380, 400, 415, 480,
    600 for the voltage designator.
    
    The 'X' in the model name indicates different construction options that do not impact
    certification due to not being part of the wetted surfaces. Models with the 'TE' or
    'TE2' designation are coated with Teflon. N4 = NEMA 4 Steel Enclosures, N4X = NEMA 4X
    Stainless Steel Enclosures, HLW = ASME HLW construction.
    
    The optional 'R' near the beginning of the model name indidcates a reverse construction.
    
    CNA/SNA model heat exchangers are manufactured in Standard models and ASME models (HLW).
    The “CNA” models are commercial/industrial series heat exchangers. The “SNA” models are
    Keltech’s safety series products and have control differences used for tepid water
    compliance for safety showers and eye-wash.
[LL] Product conforms with lead content requirements for “lead free” plumbing as defined by
     California, Vermont, Maryland, and Louisiana state laws and the U.S. Safe Drinking Water
     Act.

[2] The 'D' in the model name indicates a digital control. The numbers prior to the 'D'
    indicate the voltage on the C1N, C2N, and CLE series.
    
    The 'X' in the model name indicates different construction options that do not impact
    certification due to not being part of the wetted surfaces. Models with the 'TE' or
    'TE2' designation are coated with Teflon. N4 - NEMA 4 Steel Enclosures, N4X - NEMA 4X
    Stainless Steel Enclosures, HLW - ASME HLW construction.
    
    VAC can be 380, 400, 415, 480, 600 for the voltage designator.
    
    The C1N, CLE and C2N are water heaters. The C1N and CLE models contain identical wetted
    parts and only differ in non-wetted enclosures. The C2N models contain two heating
    elements versis the C1N/CLE models which contain only one.
[LL] Product conforms with lead content requirements for “lead free” plumbing as defined by
     California, Vermont, Maryland, and Louisiana state laws and the U.S. Safe Drinking Water
     Act.

[3] The 'D' in the model name indicates a digital control. The numbers prior to the 'D'
    indicate the voltage on the HL, H, and L series.
    
    The 'X' in the model name indicates different construction options that do not impact
    certification due to not being part of the wetted surfaces. Models with the 'TE' or
    'TE2' designation are coated with Teflon. 
    
    N4 - NEMA 4 Steel Enclosures
    
    N4X - NEMA 4X Stainless Steel Enclosures.
    
    VAC can be 208, 240, 277, 380, 400, 415, 480 for the voltage designator.
    
    The HL Series tankless water heaters have a 3/4" inlet and outlet. The L Series tankless
    water heaters have a 1/2" inlet and outlet.
