INSTALLATION
Only a qualified plumbing professional should install the Sparus
"Pump Warning And Safety Instructions" on pages ii - iii for additional installation and safety information.
Location
Be sure the pump location meets the following
requirements:
•
Pump inlet as close as possible to water level.
•
Short, direct suction piping returns (reduces friction
loss).
•
Install pump in a sheltered, well ventilated area to
protect from excess moisture (i.e., rain, splashing
water, etc.) and flooding.
•
Install and secure pump on level concrete slab or
firm surface (reduces vibration noise).
•
Pump location should allow access for servicing and
maintenance.
Piping
1. Be sure all plumbing connections are clean and tight
to avoid possible air leaks and entrainment of air on
the suction side of the pump.
2. Gas supersaturation conditions resulting from air
entrainment can be harmful to aquatic animal health.
3. Use larger pipe sizes for improved plumbing. Pipe
diameter should be the same or larger as the return
line diameter.
4. Plumbing on the suction side of the pump should be
as short as possible.
5. Install piping as close to the water level as possible.
6. Run straight, horizontal piping for the suction side of
the pump. The length of the piping should be equal
to five (5) pipe diameters.
Example: If system is plumbed with 3 in. diameter
PVC pipe, than a straight section of pipe 15 in. long
should be used for suction side of the pump.
5 x PIPE DIAMETER
ELBOW
Fittings
1. Install fittings (valves, elbows, tees, etc.) in the suction
line no closer than five (5) times the pipe diameter to
the front of the pump (e.g. 3" pipe = 15 in).
2. Do not install 90° elbows directly into pump inlet.

Before operation, be sure to completely rinse
the pump volute with water.

Valves
1. Install gate valves on suction and discharge pipes for
maintenance of flooded suction systems- install no
closer than five (5) times the suction pipe diameter.
2. Use a check valve in the discharge line when using
this pump for any application where there is significant
height to the plumbing after the pump.
3. Be sure to install check valves when plumbing in
parallel with another pump. This helps prevent reverse
rotation of the impeller and motor.
Electrical
•
Install all equipment in accordance with the National
Electrical Code and all applicable local codes and
ordinances.
•
A means for disconnection must be incorporated in
the fixed wiring in accordance with the wiring rules.
•
If the supply cord is damaged, it must be replaced to
avoid a hazard. The supply cord can be purchased
separately from the manufacturer, its service agent
or a qualified electrician.
