Improper installation or maintenance of this equipment
can cause damage or personal injury.
1. When installing new equipment, check that it is suitable
for the fluid, pressures and temperatures in your system.
2. Make sure that all pressure has been vented from the
system before loosening or disassembling any part of the
piping system or valve.
3. Before pressurizing the system, make sure that all bolts
and gasket joints are tight.
4.
When starting up the system, open inlet and outlet stop
valves slowly to prevent fluid hammer and thermal shock.
5. Use genuine Leslie replacement parts. Other parts may
look the same but may have lower strength or
temperature limits.
If you have any questions about the installation, repair or
operation of your Leslie equipment, please call Leslie
Controls or your local representative.
NOTE:
Unit is shipped with jumper wire in position J5 for pressure applications.
For temperature applications, move jumper wire to position J6.
J1 CONNECTS “EXT SET” POINT VOLTAGE (0.4 TO 2 VOLTS) TO TB-2 TERMINAL 8
(MARKED AUX# ON PC BOARD)
J2 CONNECTS “PV” VOLTAGE (0.4 TO 2 VOLTS) TO TB-2 TERMINAL 9 (MARKED AUX
