Hydrolevel 270SV - Manual

WARNING: To prevent
electrical shock or equip-
ment damage, power must
be off during installation or servicing
of the control. To prevent serious
burns, the boiler should be thorough-
ly cooled before installing or servic-
ing control. Only qualified personnel
may install or service the control in
accordance with local codes and
ordinances. Read instructions com-
pletely before proceeding.
The 3/4" NPTprobe must be installed
at a location just below the highest
permissable water level. The probe may
be installed in any metal tank, boiler, or
equalizing line. When installed in an
equalizing line, a proper blowdown
valve should be installed for regular
maintenance.
IMPORTANT: To assure proper
drainage, pipe diameter should be no
less than 1" on installations in vertical
piping.
Remove the control cover and slide key-
hole slots over probe mounting screws
and tighten screws (with either a 1/4" hex
head driver or flat screwdriver). Connect the ring terminal wire lead to the probe termi-
nal stud and secure with the lock washer and wing nut
provided. With the power removed, proceed with
installation and wiring described on next page. Check to insure 1/4" clearance from the probe to
any surface inside the boiler, tank or tee. Apply
pipe sealing compound to threads.
Note: Use of Teflon tape is not recommended.
