CONNECTING THE WATER SUPPLY
NOTE: Bollente recommends covering the unit with plastic or other impermeable sheeting until all water connections
have been installed and tested, to protect the internal parts from potential leaks. Leave the tubing manifold connections
uncovered for access.
The unit must be connected to the local potable water supply.
The MODEL TR/TC has two plumbing connections:
• 3/4˝ MNPT male (blue) cold water supply inlet (lemost when facing the unit)
• 3/4˝ MNPT male (red) hot water outlet

Cold Water Inlet Connection (Blue Arrow)
First, connect the inflowing Cold Water Supply to the INLET connection, indicated by the Blue “Inlet Water”
tag. This is accomplished by connecting the recommended ¾˝ x 12˝ stainless steel braided flex hose from the
potable cold water supply to the unit’s ¾˝ NPT inlet. Using a wrench, attach the stainless flex lines to the inlet
connection.
NOTE: Take care to NOT over-torque these connections (both cold and hot.) Doing so induces stress on the
heating manifold assembly. Manifolds damaged by over-tightening these connections are NOT covered by
warranty.
