FOR PROFESSIONAL USE ONLY
JB manifolds are designed for use by technically trained
AC/R service engineers only. Due to the high pressures encoun-
tered in all systems that this manifold will be used on, plus the
dangers due to the physical and chemical nature of refrigerants
and oils present in all systems, misapplication could result in
injury or death.
LIMITED WARRANTY
Manifold bar has a lifetime warranty, while the components, i.e.
gauges, hoses, handles, hose holders, etc. are covered under
the limited warranty policy. Products are warranted for a period
of one year from date of shipment by JB and limited to repair,
replacement or credit, if in our opinion are defective due to
workmanship and/or materials. Defective components should be
returned to the wholesaler from which the product was pur-
chased for evaluation.
Manifolds are designed for use with all refrigerants except
ammonia (R-717). Working pressures are limited to gauge dial
range. Use of this manifold under any other conditions voids the
warranty.
