a maximum lift of 4.9 m (16 ft). Dual floats are included with the unit. One float is used for
condensate pump control; the other is to generate condensate pan overflow alarms.
2. ACRC500/ACRP500 Series
a. The factory-installed condensate pump is piped internally to the condensate pan. It is capable
of pumping 31.8 l/h (8.45 GPH) liquid a maximum distance of 18 m (60 ft), which may include
a maximum lift of 3.5 m (11.5 ft). Dual floats are included with the unit. One float is used for
condensate pump control, the other to generate condensate pan overflow alarms.
M. DEW POINT CONTROL PUMP (ACRC301H ONLY)
1. The dew point control pump is piped internally to the cooling unit and recirculated water into the
