condition.
2. Check the ratings given in the instructions and on the

WARNING
Explosion Hazard.
Can cause serious injury, death or property
damage. This product is intended for use only
in systems with a pressure relief valve.
WARNING
Electrical Shock Hazard.
Can cause serious injury or death. Disconnect
power supply before beginning installation to
prevent electrical shock or equipment dam-
age.
CAUTION
Equipment Damage Hazard.
Use of incorrect device or improper installa-
tion can damage the system.
1. Do not replace immersion-type Aquastat
Controller with strap-on Aquastat Controller.
2. Do not secure draw nut so tightly that
retainer clamp can collapse tubing.
IMPORTANT
1. Terminals on these Aquastat relays are approved for
copper wire only.
2. Controller may be used with or without immersion well. If
used, well must snugly fit sensing bulb for best thermal
response. Insert bulb until it rests against the bottom of
the well. Use well of correct length and bend the tubing,
if necessary, to provide enough force to hold the bulb
against the bottom of the well. Avoid making a sharp
bend in the tubing as it can produce a break in the
tubing and cause loss of fill. This condition causes the
High and Low Limit controls to be made continuously.
3. If well does not snugly fit on bulb, use the heatconductive
compound, included with Super Tradeline and Tradeline
models, as follows: Fold the plastic bag of compound
lengthwise and twist gently. Snip the end of the bag
and insert into the well. Slowly pull out the bag while
squeezing firmly to distribute compound evenly in the
well. Insert the bulb into the well. Bend the tubing, if
necessary, to provide force to hold the bulb against the
bottom of the well and to hold the outer end of the bulb
firmly in contact with the side of the well. Wipe off excess
compound

The manufacturer usually provides a tapping for insertion
of the controller sensing element. This tapping is located at
a point where typical water temperature can be measured.
Depending on the model, the element is inserted in an
immersion well, through a boiler fitting, or directly immersed.
Installation should be made by a qualified service technician.
Follow the instructions furnished by the system manufaturer,
if available. Otherwise, refer to appropriate procedure listed
below.
