WARNING
Pass electrical cable under water hoses to prevent tripping hazard.
(7)
Remove cover from RAW WATER PUMP NO. 2 receptacle on junction box. Connect raw water
pump No. 2 electrical cable to receptacle.
(8)
Remove cover from RAW WATER PUMP NO. 1 receptacle on junction box. Connect raw water
pump No. 1 electrical cable to receptacle.
(9)
Check security of all hose coupling connections.
o.1
Setup Raw Water System Using; Ocean Intake Structure Refer to Figure 2-36a. This procedure applies the
Ocean Intake Structure which is supplied with Models H-9518-1) H-9518-2 and H-9518-3 only. The Ocean
Intake Structure is used in place of the strainer and float.
WARNING
l
To prevent contamination of product water system, do not use hoses intended for
potable product water in the raw water system. Product water hoses are identified by
a blue stripe running the full length of the hose.
l
Position hoses so that a tripping hazard does not exist in front of control panel.
CAUTION
Ensure all gaskets are in place and quick disconnect couplings are locked. Raw water
pumps will not prime if suction hoses draw air.
NOTE
•
ROWPU should be positioned as close as possible to the water source.
If ROWPU
is less than 60 feet from water source, only raw water pump No. 2 is required for
operation.
•
Raw water pump No. 1 has a female coupling on the pump suction port and male on
the discharge port. Pump No. 2 has female couplings on both suction and discharge
port
•
Ensure all gaskets are in place and quick disconnect couplings are locked.
•
Use the minimum number of hoses required to connect raw water pump to No. 2 to
control panel.
(1)
Connect canvas discharge hoses between the RAW WATER coupling on the control panel and
discharge coupling of raw water pump No. 2.
(2)
Connect canvas discharge hose between suction coupling of raw water pump No. 2 and discharge
coupling of water pump No. 1.
NOTE
The installation of the Ocean Intake Structure should be performed at maximum low
tides. This should eliminate the need to move the wellpoints as tides change.
(3)
Install pump adapter fittings on the inlet and outlet of raw water pump No. 1.
(4)
Attach the 1 1/2 ” pipe nipple, 2” gate valve and adapter fitting to the outlet of raw water pump
No. 1.
