It is important to follow best pracces for mounng the system
pump to provide long life, serviceability, and the ability to purge
air out of the system. Following are two important ps for
ensuring a good installaon:
•  Pumping up is the best way to mount
the pump. If there is air in the system, it will have the best
chance of the air geng though the pump, to the air
separator, and out of the system. If the pump air locks, turn
the pump o and the air will go up out of the impeller and
will be replaced with water. Restart the pump and it will
start pumping. The air will ow to the air separator. In most
cases the air will go through the pump. Pumping
horizontally will work as long as there are small pockets of
air in the system. They will keep moving around the system
with the water to the air separator. If there are big pockets
of air in the system, this will create problems for horizontal
mounng. The pump will cavitate, lose water ow,
overheat, and fail. If the pump does get air locked, there will
need to be a purge port so that the air can be ushed out of
the pump and system. Pumping down is the poorest way to
mount a pump. If there is air in the system it will get
trapped in the pump, causing it to cavitate, loose water
ow, overheat, and fail. The air creates resistance in the
down owing water because the air wants to ow up. If the
pumps loses ow or stops, the air comes back up the pipe
into the impeller, amplifying the problem. If the pump gets
air locked, there will need to be a purge port so that the air
can be ushed out of the pump and system.
•  The pump is a wet rotor pump. The
motor sha must be horizontal to keep the bearings
properly lubricated. Do not put the pump on its back or
poinng down (vercal sha) because this orientaon can
cause premature pump failure. In most cases, the direcon
of the electrical box is important to keep any condensaon
out of the windings. Some pumps have a yellow scker that
is on the head of the pump, indicang the proper direcon.
Piping diagrams in  are schemacs. Not all
components are shown, such as union ngs, piping adapters/
reducers, and other components. Schemacs are designed for
illustrang the arrangement/funcon of the components.
Always use best pracces when considering the locaon of the
various components. For example, the expansion tank must
always be on the sucon side of the pump; check valves (if
applicable) must always be on discharge of the pump.
