BATTERIES
Single Point Watering System (SPWS)
16
INITIAL MAINTENANCE OF THE SPWS
After six-weeks of operation, remove the valves from the batteries and manually check the battery water level to ensure
that the SPWS is not leaving any cells dry. This initial electrolyte level check on all the battery cells verifies that all the
valves in the SPWS are functioning correctly. If a valve fails to open, the cell will eventually dry out. The initial one-time
inspection of all cells will identify any occurrence of a valve that fails to open. If a valve fails to close, it will become
evident due to the cell overflowing during routine watering. Either failure scenario is rare, but should be monitored in the
initial inspection and during routine watering sessions. Replace malfunctioning valves to ensure maximum battery life.
After the initial six-week inspection, manually check the battery water levels at least once per year, particularly after
winter storage or any other period of vehicle inactivity.
See following NOTE.
NOTE:
For the longest battery life, be sure the mineral contents of the water meet the minimum requirements as
stated in the vehicle’s appropriate maintenance and service manual.
See Mineral Content on page 16-19.
WATERING BATTERIES WITH THE SPWS
Checking the Water Flow Rate
1.
Connect the water hose with the built-in screen filter (2) to the water faucet (1)
(Figure 16-11, Page 16-23)
.
See following CAUTION.
CAUTION
• Make sure the screen filter is clean.
• Do not use a longer garden hose than provided with the System (20 feet), as a decrease in water
pressure could overfill the batteries and damage the refill system.
2.
Before screwing the hose-end assembly (3) onto the opposite end of the water hose, check the screen filter (4)
inside the end of the assembly to make sure it is clean
(Figure 16-11, Page 16-23)
.
3.
Connect the purger (5) to the female coupler (8) on the hose-end assembly
(Figure 16-12, Page 16-23)

Checking the Water Flow Rate
4.
Completely open the water faucet until the water flows out of the hose-end assembly (3), and note the movement
of the red flow indicator balls (6).
See following NOTE.
NOTE:
The water flow rate must be at least two gallons-per-minute for the SPWS to function properly.
This step also eliminates any trapped air from the water hose.
