Description n
Powers Series LFG480 & LFE480 are designed for lavatory
applications where the temperature of the hot water must be
controlled for safe, economic use. An advanced thermal actua-
tor quickly senses and compensate for outlet temperature fluc-
tuations induced by water temperature and pressure changes in
the supply line.

WARNING
!
Read this Manual BEFORE using this equipment.
Failure to read and follow all safety and use infor-
mation can result in death, serious personal injury,
property damage, or damage to the equipment.
Keep this Manual for future reference.
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.

0.5 ppb for lead per Section 9.5.1.1 of NSF/ANSI/CAN 61.

Temperature Adjustment n
1. Loosen locknut.
2. Turn on fixture and run water for at least two minutes to allow
supply temperature to stabilize.
3. Turn temperature stem counter-clockwise for hotter or
clockwise for colder outlet temperature.
4. Tighten locknut to prevent accidental or unauthorized
temperature adjustment.
5. Re-check outlet temperature.
Repair Kit n
Motor Repair Kit: ................................................................ 480 270
To Install n
1. 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.
2. 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.
3. Connect hot and cold supplies to valve and outlet of tem-
pering valve to fixture (s) using 1/2" or 3/8" compression
connections.
4. Turn on hot and cold water supplies. If any leaks are
observed, tighten connections as necessary to stop leaks
before proceeding.
5. 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.
