Air-Cooled Connections

Follow these procedures to make a tight joint:
1. Silver solder or braze condenser tubing ends to the female Rota-lock connectors.
2. Remove dust caps if used, making sure that component plastic seals are intact.
3. Wipe off connector and spud threaded surfaces with a clean cloth to prevent the inclusion
of dirt or any foreign material in the system.
4. Connector coupling nut should be screwed onto Rota-lock spud using the proper amount
of torque.

Pressure Relief Valves

water cooled condenser. These valves are designed to vent in emergency conditions. This ensures
vessel internal pressure does not exceed maximum allowable pressures.
Vent the relief valve outlet to a safe outdoor location in the approved manner away from people and
building openings. Vent line piping must have drain line at low point to drain condensate from line
per ASME Boiler and Pressure Code, Section VIII, Division 1.
PRESSURE RELIEF VALVES MUST BE REPLACED AFTER 5 YEARS OF SERVICE.
BEFORE REPLACING RELIEF VALVE, REVIEW REQUIREMENTS PER CURRENT
VALVE REPLACEMENT SHOULD BE MADE BY PROPERLY TRAINED PERSONNEL ONLY.
NOTE: IF RELIEF VALVE DISCHARGES, VALVE MUST BE REPLACED AFTER DISCHARGING
