1. Product Overview
The Haws Model 8123 is an emergency drench shower designed for either horizontal or vertical installation. This unit is engineered to provide immediate and effective drenching in industrial and laboratory environments where hazardous materials may be present. It features an AXION MSR hydrodynamic design stainless steel showerhead, which ensures a consistent and even water flow pattern for optimal decontamination. The shower is activated by a chrome-plated brass stay-open ball valve, equipped with a stainless steel ball and stem, ensuring reliable operation. Activation is achieved via a stainless steel pull rod with a triangular handle, making it easy to locate and operate in an emergency. A universal sign is included for clear identification of the emergency station.

3.1 Site Preparation
- Select a location that is well-lit, easily accessible, and within 10 seconds travel time from potential hazards.
- Ensure adequate drainage is available to handle the water flow from the shower.
- Verify that the mounting surface (wall or ceiling) is structurally sound to support the unit and the dynamic load of water flow.
3.2 Mounting the Unit
- Determine whether the unit will be installed horizontally or vertically based on site requirements and available space.
- Securely attach the mounting bracket to the prepared surface using appropriate hardware (not supplied).
- Assemble the shower arm and showerhead according to the provided diagrams, ensuring all connections are tight.
- Attach the assembled shower unit to the mounting bracket.
3.3 Water Supply Connection
- Connect the 1 IPS (Iron Pipe Size) water supply line to the inlet of the shower valve.
- Use thread sealant on all pipe connections to prevent leaks.
- Ensure the water supply provides sufficient flow and pressure as specified by ANSI Z358.1 (minimum 20 GPM at 30 PSI for drench showers).
- Flush the water supply line thoroughly before connecting to the shower to remove any debris.
3.4 Final Assembly and Testing
- Attach the stainless steel pull rod with the triangular handle to the valve mechanism.
- Mount the universal emergency sign in a clearly visible location near the shower.
- Open the main water supply to the unit.
- Test Activation: Pull the triangular handle firmly to activate the shower. Verify that water flows immediately and continuously for at least 15 minutes, covering the area from 33 to 82 inches above the floor.
- Check all connections for leaks.
- Record the installation date and initial test results.
4. Operating Instructions
In case of chemical exposure or other hazardous material contact, immediate use of the drench shower is crucial to minimize injury.
- Locate the Shower: Immediately proceed to the nearest emergency drench shower.
- Activate the Shower: Firmly grasp the triangular pull handle and pull it down. The stay-open ball valve will activate, providing a continuous flow of water.
- Drench Thoroughly: Stand directly under the showerhead and allow the water to drench your entire body for a minimum of 15 minutes. Remove any contaminated clothing while under the shower to ensure complete decontamination.
- Seek Medical Attention: After drenching, always seek immediate medical attention, even if symptoms are not apparent.
5. Maintenance
Regular maintenance is essential to ensure the drench shower remains in proper working condition for emergencies.
- Weekly Activation Test: Activate the shower weekly to ensure proper operation and to flush the line, preventing sediment buildup. Allow water to flow for a few seconds to verify flow and clear stagnant water.
- Annual Inspection: Conduct a thorough annual inspection of all components. Check for corrosion, leaks, damaged parts, and proper water flow.
- Showerhead Cleaning: Periodically inspect and clean the AXION MSR showerhead to ensure nozzles are clear and water flow is unobstructed.
- Valve Inspection: Check the stay-open ball valve for smooth operation and ensure it remains open without manual assistance once activated.
- Signage: Ensure the universal emergency sign is clean, visible, and undamaged.
- Winterization (if applicable): For units installed in environments subject to freezing temperatures, follow proper winterization procedures to prevent damage to the unit and ensure functionality. This may involve draining the unit or using freeze-protected models.
6. Troubleshooting
Refer to the table below for common issues and their potential solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| No water flow or low flow | Closed supply valve, clogged line, insufficient water pressure, clogged showerhead. | Check main water supply valve. Flush supply line. Verify water pressure. Clean showerhead nozzles. |
| Water leaks from connections | Loose fittings, damaged thread sealant. | Tighten connections. Reapply thread sealant if necessary. |
| Shower does not stay open | Valve mechanism issue, debris in valve. | Inspect valve for obstructions. Contact qualified service personnel for repair or replacement. |
| Water discolored or rusty | Stagnant water in pipes, corrosion in supply lines. | Perform weekly flushing. Inspect supply lines for corrosion. |
