INDOOR UNIT ACCESSORIES
Condensate Pump
A07892
Fig. 1 – Condensate Pump Accessory
On high wall fan coils, the condensate pump has a lift capability of
12 ft (3.6 m) on the discharge side with the pump mounted in the
fan coil or 6 ft (1.8 m) on the suction side if the pump is remote
mounted. The pump is recommended when adequate drain line
pitch cannot be provided, or when the condensate must move up to
exit.
Wired Remote Controller
For applications where the use of wireless remote control is not
desired, the MK units can be controlled by means of a wired
wall-- mounted control with an LCD display.
