GENERAL INFORMATION

INTRODUCTION

The RNS-4-SS is a closed loop system to supply and recycle the water used in cleaning forklift batteries.

The main objective of the RNS-4-SS is to::

1.) Remove contaminants associated with lead/acid batteries.

2.) Monitor the pH level of the water for neutralization as needed.

3.) Deter the growth of algae and bacteria via ozone purification.

The basic mechanical operation includes: pumping water from the reservoir through the filters, into a battery wash unit, through the sump assembly, and back into the reservoir.

The system consists of the following major components and assemblies.

A.) Completely self contained cabinet with integral 200 gallon tank.

B.) Electrical component area.

C.) pH meter with in-line probe.

D.) Water control solenoid valves

E.) Filters

F.) Water Pump

G.) Sump pump and float switch (remote mounted to wash cabinet)

H.) Ozone generator / neutralizer pump module

WATER MONITORING GENERAL DESCRIPTION

The pH level of the water stored in the RNS-4-SS is monitored by a panel mounted pH meter / controller which is supplied data from an in-line pH probe. In the event the water reaches preset parameters, the pH metering system is designed to shut off the system until the problem can be rectified. The only active circuit will be the recirculation mode.

WATER NEUTRALIZATION SYSTEM

The unit is designed with an onboard, manually operated neutralizer injection system that, when activated, injects approximately 6-8 ounces of solution into the tank. Actuating the recirculation circuit allows the neutralizer to be circulated and dispersed into the water.

OZONE GENERATOR GENERAL DESCRIPTION

The ozone generator supplies ozone to the water in the storage tank of the RNS-4-SS. Its function is to aid in the neutralizing process and inhibit the growth of bacteria and algae in the tank. It is designed to operate only when the pressure switch is activated, either during the recirculation or battery wash cabinet demand for flow.

FIGURE 2-1

pH PROBE INSTALLATION AND TANK FILLING PROCEDURE

The pH probe has been shipped in a wet state. It must remain wet, either in the solution which it was shipped, or its mounted position on the RNS with the cavity purged with water. If allowed to become dry, irreparable damage to the probe will occur.

A.) Verify main water shut off valve in plumbing compartment is closed prior to filling tank.

B.) Fill tank with a minimum of approximately 14” of water.

C.) Locate pH probe in plumbing compartment and remove tie strap used in shipping. See Figure 2-2.

D.) Slowly turn the main water shut off valve to the “ON” position. See Figure 2-3. Allow the air to purge from the water circuit until water just starts to come from the pH probe mounting port. See Figure 2-2.

E.) Shut off water supply valve. Carefully remove the protective cap from the pH probe. Slide the probe into the port until it is fully seated and then screw the retaining nut down. HAND TIGHTEN ONLY!

F.) Proceed to fill the tank no higher than the high water sensing switch located about 6” from the top of the left front corner.

FIGURE 2-2

FIGURE 2-3

INITIAL START UP PROCEDURE

A.) Prior to final hook up of the 3/4” pressure line to the wash cabinet, take the end of the hose and route it to the inside of the wash cabinet or a drain.

B.) Plug the RNS in to a 120 volt receptacle that is GFCI protected. See Section 2-4.

C.) Move the power toggle switch to the “on” position. The unit should start pumping immediately.

D.) Run the unit until all air is purged from the water circuit then turn the power switch to the “off” position and disconnect the power cord from the receptacle.

E.) Proceed with the connection of the pressure line to the wash cabinet.

The RNS-4-SS is now ready for normal operation.

NOTE: If the RNS is being used with a manual wash unit, follow all the instructions above except the pressure line will have a spray wand attached. Air purging can be done by depressing the trigger of the wand while powering up the RNS as described above.

OPERATING INSTRUCTIONS

The RNS-4-SS is an automatic “ON DEMAND” water supply system. Once the unit has been set up and had the initial start up procedure completed, it is ready to operate with no further requirements.

Simply put the power switch in the “ON” position and when the pressure switch senses a drop in pressure or fl ow demand, it will start the pump system as needed and shut off automatically when the demand has ceased.

PLUMBING CIRCUIT THEORY OF OPERATION

REFERENCE FIGURE 3-3

Water is pulled from the bottom outlet port of water tank through the shut off valve and a 100 mesh strainer, past the pH probe, to the pump inlet.

The water from the pressure side (outlet side) of the pump flows through a reverse flow check valve, past the main system relief valve, pressure sensor, and gauge. The relief valve is activated if there is a failure in the pump or pressure switch that could cause over pressurization to occur.

Water is then pushed through the 5 micron filter assembly to the solenoid operated water valves.

Under normal operating conditions the solenoid operated valve to the wash cabinet/wand is open and the solenoid operated valve for the recirculate mode is closed. The recirculate valve is activated only when the recirculate function is actuated.

As demand/flow is required at the wash cabinet, the output water goes into the sump area of the wash cabinet base where a fl oat switch is located.

When the water in the sump reaches a depth adequate to energize the float switch, it then energizes the sump pump mounted on the back of the wash cabinet that pumps the spent water back to the RNS return inlet.

As the water passes through the inlet it is dumped into a 50 micron bag filter to remove any debris larger than 50 microns.

The water is held in storage for recycling through the system.

ELECTRICAL CIRCUIT THEORY OF OPERATION

REFERENCE FIGURE 3-4

When the power switch is activated, the pH meter, pump motor and 12 volt DC control circuit are energized. The green power indicator light (LT1) is also energized. When the pump reaches the maximum pressure preset at the pressure switch, the switch (PS) opens and disconnects the pump motor. As a pressure drop is sensed, PS closes and initiates pump start up. PS is preset at the factory for 55 - 70 psi.

When the water tank is being filled and the level gets to its maximum point, the fl oat switch (FS1) energizes the high water indicator light (LT3). When water in the tank has been depleted to its recommended refill level, float switch (FS2) energizes the add water indicator light (LT4). If the water level falls below the minimum level required for proper operation, fl oat switch (FS3) energizes the low water indicator light (LT5) as well as relay (CR1), which in turn closes the solenoid operated valve to the wash cabinet (CR1-2) and also opens (MS1-1) and (MS1-2), disconnecting the pump circuit. The same sequence takes place in the event of pH levels going beyond preset parameters (Below 4.0 or above 10.0). The exception is LT2 being illuminated instead of LT5. Low water condition must be resolved for unit reset to normal operating conditions.

In the event of pH error, the proper chemical must be added and the recirculate mode should be energized. Actuating the recirculate energizes relay (CR3) and a timer relay (TR1). (MS1-1) and (MS1-2), and the solenoid operated valve for water circulation to tank (via CR3-1) are energized. The timer relay (TR1) is preset for a 20 minute period. After the unit times out and if the pH error has been corrected, all circuits will resume their normal state, ready for operation.

OZONE GENERATOR/NEUTRALIZING SYSTEM OPERATION

REFERENCE FIGURES 3-5, 3-6, 3-7

• DO NOT inhale concentrated ozone directly from ozone generator. Respiratory problems and lung damage will occur.

• DO NOT expose eyes to the light emitted by the ultraviolet lamp or operate the lamp if removed from its canister. Damaged or loss of vision will occur.

The ozone generator supplies ozone to the water stored in the tank to aid in purification. Whenever the pressure pump of the RNS-4-SS is energized, the ozone generator will be operating. A small diaphragm type air pump pushes air through the ultraviolet light unit which converts the oxygen in the air to ozone. It then passes through a bulkhead fitting in the tank wall and is routed to the bottom of the tank and diffused through a 12” long air stone. The ozone oxidizes dissolved hydrocarbons, metals and organic matter and is then filtered out through the 5 micron filter.

The neutralizing system is a one-shot, timed injection of a solution designed to bring the pH up to a higher level. The system is actuated by a push button located on the control console. See Figure 3-1. By depressing and holding the button for approximately 5 seconds, the system will inject approximately 8 ounces of neutralizer. The neutralizer container is located inside the plumbing compartment door. After injecting neutralizing solution, the RNS should be put in the recirculation mode to disperse the solution.

MAINTENANCE

It is imperative all equipment be inspected and maintained on a regular basis to ensure a long dependable life from your investment. The following information is a rule of thumb only and should be adjusted based on; environment, amount of run time, condition of batteries to be cleaned, etc. As you first start a battery cleaning program, you may find it necessary to have increased inspection and maintenance requirements. But if a good regimen is followed and batteries are kept in a cleaner state, these increases should subside and you will be able to get a better feel for your own individual scheduling of maintenance.

PERIODIC INSPECTIONS

On the following page is an operator/maintenance spread sheet for daily and weekly inspections. The daily tasks are noted by a (D) and the weekly tasks are noted by a (W) in the task column. Copies should be made and stored in an area of your battery room or maintenance department for accessibility by authorized personnel. Some of the inspections noted may require the removal of a particular access panel to accomplish. Refer to the parts/component location figures further back in this manual.
