Description
Mini condensate pump specifically designed for air conditioning units with limited internal space.
• Reciprocating piston pump which first sucks in, then evacuates the condensation
water.
• Consisting of a pump unit and a remote detection unit fitted with a 3 level float (on /
off / alarm).
• Alarm contact normally closed that automatically cuts off the air conditioning
system compressor or a solenoid valve.
• Thermal protection 194°F (90°C) on the pump coil.
• Electrical connection by plug.
Kit contents
• Piston pump bloc 2.6 gph (10l/h)
• Detection unit with float (SI2958)
• Rubber mounting bracket
• Power cable : 5.0 ft with 5 wires. Electrical connection by plug. Conform to UL.
• Detector installation kit : blond rubber Ø 0.59”x1.38”, vent pipe Ø 0.16” x 0.24" x
2.95”, self-adhesive mounting rail
