Powers e480 Series Under-the-Counter Combination Tempering Valves for Low Flow Control - Manual

HydroGuard ® Series LFe480
Lavatory Tempering Valve
Installation Instructions
IS-P-e480
** With Equal Pressure
Description
n
Powers Series LFe480 are 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 compensate for outlet temperature fluctuations
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 adjust-
ed 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 !
WARNING !
Need for Periodic Inspection and Yearly Maintenance:
Periodic inspection and yearly maintenance by a licensed
contractor is required. Corrosive water conditions, inlet
temperatures over 200°F (93°C), and/or unauthorized adjust-
ments or repair could render the valve ineffective for ser-
vice intended. Regular checking and cleaning of the valve’s
internal components and check stops helps assure maxi-
mum life and proper product function. Frequency of clean-
ing and inspection depends upon local water conditions.
