G3 Max

Product catalog summary

Overview: This document provides installation instructions for the G3 Vent Valve Kit, intended for professional use only. The kit is available in different configurations based on voltage and thread type, with a maximum working pressure of 3500 psi (241 bar, 24 MPa).

Kit Components: The kit includes various parts such as vent valves, cables, grease fittings, plugs, socket screws, pressure gauges, and adapters. Each part is specified for different configurations (12 VDC, 24 VDC, NPT, BSPP).

Important Safety Instructions: Users must read all warnings and instructions in this manual and the G3 Pump instruction manual. It is crucial to use tubing rated for the same pressure to avoid equipment damage. High-pressure fluid can cause serious injuries, including skin injection hazards, requiring immediate surgical treatment.

Pressure Relief Valves: The pressure relief valve is designed to protect against unintended pressure increases. It is factory set to 3000 psi (207 bar, 20.7 MPa) and requires periodic adjustments. It should not be used for routine pressure relief during normal operations.

Installation Instructions:

Disconnect the power source and relieve pressure if the unit has been in service.
Mount the vent valve block near the G3 pump using the provided socket screws.
Connect the cable to the G3 and the solenoid valve.
For BSPP kits, install the adapter before the pump element fitting.
Connect the inlet tube to the pump element fitting and manifold port.
Connect the main tube to the manifold outlet and injector inlet.
Loosen the plug from the return location and apply thread sealant to the tube fitting.
Install and tighten the tube fitting, then connect the vent tube between the vent port and fitting.

Additional Parts: The kit includes optional parts like a Zerk grease fitting, plugs for open outlet ports, and a pressure gauge. Unused ports must be sealed with plugs.

Retrofitting Existing Installations: For retrofitting, disconnect the power source, relieve pressure, and remove existing plumbing. Follow the installation steps provided.

Notes: The document includes diagrams and figures to assist with installation. Graco reserves the right to make changes without notice, and the manual reflects the latest product information as of its publication date.

Instructions Pressure Relief Valves The pressure relief valve uses a pressure adjustment screw (a) to set the pressure release point. It is not intended as a way to relieve pressure during normal operation but as a protective measure in the event there is an unintended pressure increase in the system. Relieve pressure in system by using two wrenches working in opposite directions on pump element and pump element fitting to only loosen fitting. NOTE: When loosening pump element fitting, do NOT loosen pump element. Loosening pump element will change the output volume. NOTE: • Do not use this pressure...

3. Mount vent valve block (1) to a fixed surface near the G3 pump using mounting holes (b) and two socket screws (5). 1 NOTE: If using one of the BSPP Vent Valve Kits, install adapter (7) into pump element prior to installing pump element fitting (c) then continue installation, Step 6. 6. Connect inlet tube (c) to pump element fitting (d) and inlet fitting (e) to manifold port (stamped with an “I”) (FIG. 5). Wrench tighten only. FIG. 2: Mounting Dimension a = 3.25 inches (8.255 cm). Thread 1/4 - 20 UNC-2A 4. Connect end of cable (2) to the G3 (FIG. 3). FIG. 5 7. Connect main tube (f) to any manifold...

9. Apply thread sealant (user supplied) to threads (k) of a tube fitting (m). NOTE: Although the example shown in FIG. 8 shows a 90° elbow fitting, this is only shown for reference. The user may use what ever fitting best suits their installation. 10. Install tube fitting (m) in open port. Plugs (must be installed in any open outlet port) (5) Pressure Gauge (optional) (7) Install any of these parts in the remaining outlet ports on the manifold block. NOTE: Any port not used by a pressure gauge (7) or zerk grease fitting (4) MUST have a plug (5) installed in the opening. Retrofitting Existing...
