IMPORTANT:
To avoid damaging the float, ensure that the float is not subject to pressures exceeding these
limitations:
• 100 psig (690 kPa) for copper float
• 150 psig (1035 kPa) for polycarbonate float
!
WARNING: Risk of Electric Shock.
Disconnect the power supply before making electrical connections. The printed circuit
board and its components are at AC line voltage. Contact with components carrying
hazardous voltage can cause electric shock and may result in personal injury or death.
AVERTISSEMENT : Risque de décharge électrique.
Débrancher l'alimentation avant de réaliser tout raccordement électrique. Le circuit imprimé
et ses composants présentent une tension CA. Tout contact avec des composants porteurs
de tensions dangereuses risque d'entraîner une décharge électrique et de provoquer des
blessures graves, voire mortelles.
IMPORTANT:
Use copper conductors only. Make all wiring connections in accordance with local, national, and
regional regulations. Do not exceed the flow switch’s electrical ratings.
IMPORTANT:
Use the terminal screws provided
(8-32 x 1/4 in. binder head). Substitution of other screws voids the warranty and agency approvals.
