WRAP SERVICE VALVES

To help protect service valve seals during brazing, wrap water-saturated cloths around service valve bodies and copper tube stubs. Use

additional water-saturated cloths underneath the valve body to protect the base paint.

FLOW NITROGEN

Flow regulated nitrogen (at 1 to 2 psig) through the refrigeration gauge set into the valve stem port connection on the liquid service valve and

out of the vapor valve stem port. See steps 3A, 3B and 3C on manifold gauge set connections.

BRAZE LINE SET

Wrap both service valves with water-saturated cloths as illustrated here and as mentioned in step 4, before brazing to line set.

Cloths must remain water-saturated throughout the brazing and cool-down process.

Allow braze joint to cool. Apply

IMPORTANT —

additional water-saturated cloths to help cool brazed

joint. Do not remove water-saturated cloths until

piping has cooled. Temperatures above 250ºF will

damage valve seals.

FIRE, PERSONAL INJURY, OR PROPERTY DAMAGE

may result if you do not wrap a water-saturated cloth around

both liquid and suction line service valve bodies and copper

tube stub while brazing the line set! The braze, when

complete, must be quenched with water to absorb any

residual heat.

Do not open service valves until refrigerant lines and

indoor coil have been leak-tested and evacuated. Refer

to Installation and Service Procedures manual.

After all connections have been brazed, disconnect manifold gauge set from service ports. Apply additional water-saturated cloths to both

services valves to cool piping. Once piping is cool, remove all water-saturated cloths.

WHEN BRAZING LINE SET TO

SERVICE VALVES, POINT FLAME

AWAY FROM SERVICE VALVE.
