POWER LFG480 Series Lavatory Tempering Valve
Product Information
Product Name: Powers Series LFG480 & LFE480
Description: Designed for lavatory applications
where the temperature of the hot water must be controlled for safe, economic
use. An advanced thermal actuator quickly senses and compensates for outlet
temperature fluctuations induced by water temperature and pressure changes in
the supply line.
Specifications:
- LFG480 Flow Capacity: 0.25 gpm (1.0 lpm)
- LFE480 Flow Capacity: 0.50 gpm (1.9 lpm)
- Listing: ASSE 1070, IAPMO cUPC, and NSF 61-9 & 372
Product Usage Instructions
To Install
- Flush all piping thoroughly before installation.
- Locate a suitable place for the tempering valve. It should be accessible for service and adjustment and as close to the point-of-use as possible.
- Connect the hot and cold supplies to the valve and the outlet of the tempering valve to the fixture(s) using 1/2 or 3/8 compression connections.
- Turn on the hot and cold water supplies. If any leaks are observed, tighten connections as necessary to stop leaks before proceeding.
Temperature Adjustment
- Loosen the locknut.
- Turn on the fixture and run water for at least two minutes to allow the supply temperature to stabilize.
- Turn the temperature stem counter-clockwise for hotter or clockwise for colder outlet temperature.
- Tighten the locknut to prevent accidental or unauthorized temperature adjustment.
- Re-check the outlet temperature.

WARNING
- Read this Manual BEFORE using this equipment.
- Failure to read and follow all safety and use information can result in death, serious personal injury, property damage, or damage to the equipment.
- Keep this Manual for future reference.
WARNING
You are required to consult the local building and plumbing codes prior to
installation. If the information in this manual is not consistent with local
building or plumbing codes, the local codes should be followed. Inquire with
governing authorities for additional local requirements.
WARNING
FAILURE TO COMPLY WITH PROPER INSTALLATION AND MAINTENANCE INSTRUCTIONS COULD
CONTRIBUTE TO THE VALVE FAILURE, RESULTING IN INJURY AND/OR DEATH.
TO ENSURE THE ACCURATE AND RELIABLE OPERATION OF THIS PRODUCT, IT IS ESSENTIAL
TO:
- Properly design the system to minimize pressure and temperature variations.
- This valve is factory preset. However, it can be adjusted to deliver scalding temperatures. Check outlet tem-perature to ensure it does not exceed 105°F (41°C). Make sure temperature limit stop is properly re-set to maximum 105°F (41°C) following valve maintenance or repair. Tampering with limit stop in any way may result in scalding temperature causing serious bodily harm and/or death.
WARNING
Need for Periodic Inspection and Yearly Maintenance: Periodic inspection and yearly maintenance by a licensed con-tractor is required. Corrosive water conditions, inlet temperatures over 200°F (93°C), and/or unauthorized adjustments or repair could render the valve ineffective for service intended. Regular checking and cleaning of the valve’s internal components and check stops helps assure maximum life and proper product function. Frequency of cleaning and inspection depends upon local water conditions.
This product meets the reduced Q test statistic criteria of 0.5 ppb for lead per Section 9.5.1.1 of NSF/ANSI/CAN 61.

To Install
- Installation should be in accordance with acceptable plumb-ing practices. Flush all piping thoroughly before installation. Installation and field adjustment are the responsibility of the installer.
- Locate suitable place for the tempering valve. Valve should be accessible for service and adjustment and as close to the point-of-use as possible.
- Connect hot and cold supplies to valve and outlet of tem-pering valve to fixture (s) using 1/2″ or 3/8″ compression connections.
- Turn on hot and cold water supplies. If any leaks are observed, tighten connections as necessary to stop leaks before proceeding.
- Turn on fixture and allow water to flow for 2 minutes. Measure water temperature at the outlet. If water is not at desired temperature, adjust as necessary (see temperature adjustment section). Maximum outlet temperature of 105°F (41°C) is recommended.
Temperature Adjustment
- Loosen locknut.
- Turn on fixture and run water for at least two minutes to allow supply temperature to stabilize.
- Turn temperature stem counter-clockwise for hotter or clockwise for colder outlet temperature.
- Tighten locknut to prevent accidental or unauthorized temperature adjustment.
- Re-check outlet temperature.
