CAUTION
Installation of an anchor weight
Using an anchor weight that is heavier than 6 kg (13.23 lb) may cause internal damage to
the temperature probe.
‣
Ensure that the anchor weight is stable at the bottom of the tank. When installing
NMT81 with a suspended anchor weight, use an anchor weight that weighs 6 kg
(13.23 lb) or less.
Anchor weight installation procedure
1. Tie the bottom hook of the temperature probe or the WB probe to the anchor
weight's ring using a tension wire.
2. Wrap the tension wire twice around the bottom hook. Pull it downwards and tie it
down, and then bundle it with the provided securing wire.
3. Using bolts, secure the flange of NMT81 to the nozzle at the top of the tank.
