Warnings WARNING SKIN INJECTION HAZARD High-pressure fluid from gun, hose leaks, or ruptured components will pierce skin. This may look like just a cut, but it is a serious injury that can result in amputation. Get immediate surgical treatment. • Do not point gun at anyone or at any part of the body. • Do not put your hand over the spray tip. • Do not stop or deflect leaks with your hand, body, glove, or rag. • Do not spray without tip guard and trigger guard installed.
Installation Installation Fluid pressure regulators are used for accurate, positive control of the fluid pressure to spray guns, dispense valves, or atomizing heads. Regulators installed at circulating line take-offs or pumps are used to reduce main line pressure and maintain the desired fluid pressure to the spray gun, dispense valve, or atomizing head. Connect Electrical Cable 1. Wrap hose cable around hose one time.

Operation Ground the System Operation Pressure Relief Procedure The following grounding instructions are minimum requirements for a basic dispensing system. Your system may include other equipment or objects that must be grounded. Check your local electrical code for detailed grounding instructions for your area and type of equipment. Your system must be connected to a true earth ground. • Fluid regulator: ground by connecting to a properly grounded fluid hose and by a ground wire in the cable.
Maintenance Maintenance Flushing Trapped air can cause the pump to cycle unexpectedly, which could result in serious injury from splashing or moving parts. Cleaning When changing materials, the regulator should be disassembled and cleaned. Regular cleaning and inspection, and lubrication of the piston (7) and piston packing (12) are necessary to keep the fluid regulator working properly. 1. Relieve all the air and fluid pressure in the system.
Troubleshooting Troubleshooting Some solutions require disassembling fluid regulator. Always relieve system pressure and disconnect electrical cable before performing these procedures. Problem Regulator does not heat material Cause(s) Solution(s) Loose heater wires. Check and reconnect wire connections. Loose sensor wires. Check and reconnect wire connections. Heater cartridge failed. Replace failed heater. Sensor failed. Replace failed sensor. Temperature controller failed.
