Emerson YARWAY CONDENSAVER Series Installation, Operation And Maintenance Instructions

YARWAY CONDENSAVER™ SERIES STEAM CONDENSATE RETURN PUMPS
INSTALLATION, OPERATION AND MAINTENANCE INSTRUCTIONS
Before installation, these instructions must be carefully read and understood.

INSTALLATION

The unit should be installed in a level position.
Follow the piping arrangement of Figure 1 for
a vented receiver application or Figure 2 for a
pressurized receiver application.
Upstream piping must always be equal to or
larger than the check valve connection size
and block valves must be full ported to achieve
rated capacities. The pump should not be used
to support the weight of the piping.
To prevent water hammer and damage to
the pump's outlet check valve when lifting
condensate large heights, install a check valve
at the highest point of the return line.
Vented Receiver and Pressurized Receiver
To prevent upstream equipment flooding
while the pump is discharging, a condensate
receiving vessel should be installed directly
above the CondenSaver™ Series with the
necessary filling head distance between the
bottom of the receiver and the top of the pump.
