4. Setup & Installation
4.1 Pre-Installation Checklist
- Verify power supply: 240V, 3 Phase, 88 Amps.
- Ensure adequate space for the unit (Length: 17 1/2 Inch, Width: 20 3/4 Inch, Height: 23 1/4 Inch) and access for servicing.
- Confirm water supply and drain connections are available.
- Review local electrical and plumbing codes.
4.2 Mounting the Unit
The boiler is designed for floor installation. Select a level, stable surface capable of supporting the unit's weight (approximately 140 lbs). Ensure sufficient clearance around the unit for ventilation and maintenance access. Refer to the installation diagram (not pictured) for recommended clearances and mounting points.
4.3 Plumbing Connections
- Connect the water supply line to the designated inlet on the boiler. An inline shut-off valve and backflow preventer are recommended.
- Connect the 3/4 Inch drain port to an approved drainage system. Ensure proper slope for gravity drainage.
- Install the two 3/4 Inch NPT steam heads in the steam room according to the steam room design specifications. Connect the steam lines from the boiler to these heads.
4.4 Electrical Connections
All electrical work must be performed by a licensed electrician.
- Ensure the main power supply is OFF at the circuit breaker.
- Connect the 240V, 3 Phase power supply to the boiler's electrical terminal block (Electrical Location: Side).
- Properly ground the unit as per local electrical codes.
- Connect the optional D24/7 digital time clock and ADI-D Auto drain system if applicable.
- Connect the alarm circuit panic button if required.
5. Operating Instructions
5.1 Initial Startup
- After installation, ensure all plumbing and electrical connections are secure and leak-free.
- Open the water supply valve to the boiler.
- Restore power to the unit at the circuit breaker.
- The boiler will begin to fill with water. The 3-level water sensing system will monitor the water level.
- Once the appropriate water level is reached, the heating elements will activate, and steam production will begin.
5.2 Normal Operation
The Amerec AI Series boiler is designed for automatic operation. Once powered on and filled, it will maintain steam production as needed. The electronic high-limit pressure control systems regulate the steam output.
- Steam Production: Steam will be delivered to the steam room via the steam heads.
- Temperature Control: The room high-limit temperature safety system monitors the steam room temperature.
- Water Level: The sight glass allows visual inspection of the water level. The low water cut-off system will automatically shut down the unit if water levels are critically low, requiring a manual reset.
5.3 Shutting Down the Unit
To shut down the unit, turn off the power at the main circuit breaker. If an optional D24/7 digital time clock is installed, it can be used to schedule on/off times.
6. Maintenance
WARNING: Disconnect all power to the unit before performing any maintenance.
6.1 Regular Cleaning
- Drain Port: Periodically open the 3/4 Inch drain port to flush out sediment and mineral buildup. The frequency depends on water quality and usage.
- Automatic Drain System (ADI-D): If equipped, ensure the automatic drain system is functioning correctly.
- Exterior: Clean the exterior of the unit with a damp cloth. Do not use abrasive cleaners.
6.2 Descaling
Mineral deposits can accumulate inside the boiler, affecting efficiency. Descaling should be performed by a qualified technician. The frequency of descaling depends on water hardness and usage.
6.3 Annual Inspection
An annual inspection by a qualified service technician is recommended to check all components, including heating elements, sensors, safety valves, and electrical connections, to ensure continued safe and efficient operation.
7. Troubleshooting
Before contacting customer support, review the following common issues and solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| No steam production | No power to unit | Check circuit breaker. Ensure unit is properly wired. |
| No steam production | Low water level / Low water cut-off activated | Ensure water supply is open. Manually reset low water cut-off if necessary after verifying water level. |
| No steam production | High-limit pressure control activated | Allow unit to cool. Check for obstructions in steam lines or steam heads. |
| Unit leaks water | Loose plumbing connections | Tighten all plumbing connections. Inspect for damaged seals or pipes. |
| Steam room not hot enough | Improper room size for boiler capacity | Verify steam room ACF is within the 550-900 range. Consult a professional if room is too large. |
For issues not listed or if troubleshooting steps do not resolve the problem, contact Amerec customer support or a qualified service technician.
