5.1 Care to be taken while routing the condensate pump discharge line: (Refer to Fig. 6)
1. The outlet line size should be equal to or more than pump outlet flange size provided
with pump.
2. As far as possible, the discharge line should have minimum bends. Ideally the
condensate pump discharge line should be lifted immediately after the pump to the
maximum elevation in the circuit and then to be connected to feed water tank with a
downward slope. This ensures minimum back pressure on the pump .

5.2 In case more than one condensate pump is connected to a common Condensate
line: (Refer to Figure 7)
1. Make sure that NRV supplied with pump is installed with flow direction towards FWT.
The NRV size should be equal to the pump outlet line size.
2. If more than one-pump discharge lines are to be connected to a common condensate
line, please ensure that the individual line is connected from the top with a non-return
valve. The common condensate line should be sized to take care of connected
condensate load of all the pumps.
