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.
