Setup and Installation
Proper installation is crucial for the safe and effective operation of your Delta Auto Purge Drain. It is recommended that installation be performed by a qualified professional.
Safety Precautions:
- Ensure all power to the steam generator is turned off at the circuit breaker before beginning installation.
- Verify that the voltage of the auto purge drain (240v) matches the voltage of your steam generator.
- Wear appropriate personal protective equipment (PPE), such as safety glasses and gloves.
- Follow all local plumbing and electrical codes.
Installation Steps:
- Locate the Terminal Block: Identify the factory-installed auto drain terminal block inside the steam generator cabinet. Refer to your steam generator's manual for its exact location.
- Connect Electrical Wiring: Connect the electrical wiring from the auto purge drain to the designated terminals on the steam generator's auto drain terminal block. Ensure connections are secure and follow the wiring diagram provided with your steam generator.
- Connect Plumbing:
- Connect the 1/2" NPT female brass connection of the auto purge drain to the appropriate drain line from the steam generator.
- Ensure all plumbing connections are watertight to prevent leaks.
- The drain operates by gravity, so ensure proper slope for drainage.
- Secure the Unit: Mount the auto purge drain securely in a location that allows for proper drainage and access for future maintenance.
- Test System: Once installation is complete, restore power to the steam generator and test the system according to the operating instructions.
For general steam shower installation guidelines, refer to the image below. While this image provides general system setup, specific connections for the auto drain are detailed above.
Figure 3: General Steam Shower Installation Guidelines. This image outlines general requirements for steam shower installation, including enclosure, materials, and generator placement. It emphasizes that the shower area must be enclosed, insulated, tiled, and waterproof, and generators can be installed up to 50 feet from the shower area.
Operating Instructions
The Delta Auto Purge Drain operates automatically in conjunction with your 240v Delta steam generator. No manual intervention is required for its primary function.
Automatic Operation:
- When the steam generator completes its cycle and the water inside cools down, the auto purge drain will automatically open.
- The cooled water and any accumulated sediment will be drained from the generator by gravity.
- Once the generator is empty, the drain will automatically close, preparing the system for the next use.
System Interaction:
The auto purge drain is an integral part of the Delta SimpleSteam™ system. Understanding how the overall system works can provide context for the drain's function.
Figure 4: How a SimpleSteam™ System Works. This image explains the three main components of a Delta SimpleSteam™ system: the Steam Control (adjusts temperature), the Steam Generator (boils water), and the Steam Head (distributes steam). The auto purge drain works in conjunction with the steam generator to maintain its efficiency.
Maintenance
The Delta Auto Purge Drain is designed for minimal maintenance due to its automatic operation. However, periodic checks of the overall steam system are recommended to ensure optimal performance.
General Maintenance Tips:
- Inspect Drain Line: Periodically check the drain line connected to the auto purge drain for any obstructions or blockages. Ensure water flows freely during the purge cycle.
- Check for Leaks: Visually inspect all connections around the auto purge drain and steam generator for any signs of leaks. Address any leaks promptly.
- Generator Descaling: While the auto purge drain helps reduce mineral buildup, consult your steam generator's manual for recommended descaling procedures. Regular descaling of the generator will further enhance the effectiveness of the auto drain.
- Clean Exterior: Keep the exterior of the auto purge drain unit clean with a soft, damp cloth. Avoid abrasive cleaners.
