SAFETY

INSTRUCTIONS

This safety alert symbol will be used in this manual and on the

pump Safety Instruction decal to draw attention to safety related

instructions. When used, the safety alert symbol means AT-

TENTION! BECOME ALERT! YOUR SAFETY IS INVOLVED!

FAILURE TO FOLLOW THE INSTRUCTIONS MAY RESULT IN

A SAFETY HAZARD.

APPLICATION

To increase the overall efficiency of a hot water recirculation

system, the TC-1 timer control kit and the AQS-

/2 and AQS-

aquastat kits can be installed for use on any B&G NRF, NBF or

Series PL circulator. The TC-1 timer control is programmable

to turn the circulator ON and OFF automatically at preset

times. The aquastat kits switch the pump OFF at 120°F

(48.9°C) and ON at 100°F (37.8°C). The timer and aquastat kits

can be used in combination or they can be used separately.

This permits the user to have the pump circulate hot water

only during those times when high usage can be expected

throughout the day. When the aquastat kit and timer are used

together, the pump will only circulate water when the ON time

conditions are met and when the water temperature is low

enough to cause the aquastat to switch ON.
