58 InRow™ Chilled Water Air Conditioners Technical Specifications 990-4618A-001
L. CONDENSATE PUMP
1. ACRC100 Series
a. The factory-installed condensate pump is piped internally to the condensate pan. It is capable
of pumping 5 L/h (1.3 GPH) liquid a maximum distance of 15.2 m (50 ft), which may include
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 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.
