Detergent Selection

CAUTION

Using the correct detergent is critical to the performance and longevity of your parts washer.

The manufacturer does not warranty this spray wash cabinet against rust. Rust will occur if the proper detergent is not used, if start-up procedure is not followed, or if your machine is not used on a regular basis. If not regularly used oil should be used on the inside of the machine. Rust can also occur if you use D.I.water for rinsing.

A detergent formulated for mild steel

Meeting the following criteria should be met:

• The detergent must have rust inhibiting agents.
• The detergent should be strong enough to remove the contaminants, but not so strong that it attacks the metal substrate.
• The detergent should only leave an acceptable amount of residue on the parts. For new parts, you may need a detergent that is “free rinsing”.
• For use in spray wash cabinet, the detergent must be “low foaming”.

The manufacturer offers a line of detergents developed for use in spray wash cabinets. For information contact our sales department. If the parts are critical, it is the customer’s responsibility to perform any metallurgical tests.

Operation

The controls for the spray cabinet are as follows:

• CIRCUIT BREAKERS: These are located on the back of the unit inside the circuit box. The circuit breakers are used to power on/off the machine.
• CYCLE TIMER: located on the side of The cabinet above the door latch. Used

To control the wash cycle.

• OIL SKIMMER: Controlled by a toggle switch located on junction box behindthe skimmer wheel.
• THERMOSTAT: Located inside the back cover of the machine. Used to control the water temperature in the tank. This should be set to a temperature of 140-160 degrees F.
• SAFETY SWITCH: Prevents pump From operating when the door is open.

WARNING

Do not use the safety switch to purposely stop the wash cycle.

Check water level before starting the machine. The ideal water depth in the holding tank is 8″. Water should be even or just above the filter basket. Water level should be checked daily. To heat the solution in the tank, turn the heat breaker to the on position. Allow at least 1 hour for the solution to reach 140- 160 degrees F before first wash cycle. During daily operation the heating elements work automatically as needed. When solution has reached proper temperature, turn all other breakers to the on position. Place parts on the wash rack making sure parts are placed to allow rotation of the wash rack. Small parts can be placed in wash baskets provided with the machine. Close and latch the door and set the timer to start the wash cycle. Generally, most wash cycles should be 15-20 minutes.

WARNING

• Make sure door is latched before starting the wash cycle.
• Wear proper protective equipment when removing parts from wash cabinet.

The oil skimmer is not designed for constant use. When floating oil is 1/4″to 1/2″ deep, or When oil starts to impede cleaning, operate the skimmer. Before operating oil skimmer place a collection container at the oil Skimmer to collect material skimmed. Follow all regulations for disposal of skimmed material. At the end of daily operations turn off all power to the spray wash cabinet.

DANGER

Do not use the spray wash cabinet if the door safety switch does not stop the spray pump when the door is open.

Solution Disposal

Protect your environment an protect your business from fines by handling your cleaning solution according to federal, state, and local codes. According to federal regulations, which states have to adopt asminimum standards, the dirty cleaning solution in a spray wash cabinet is generally not “hazardous waste”. The two characteristics that you have to be most concerned about are corrosivity and Ep toxicity. Ask your detergent supplier is the PH of your solution is greater than 12.5 and if so, how it can be neutralized. lo check for Ep toxicity, you would need to have a sample tested by a laboratory. Assuming that your solution is not hazardous, or that with minor treatment (e.g. adding acid) the solution can be made non- hazardous, the EPA does not require special storage, documentation, transportation, and processing. Since your solution will have oils, however, you will probably not be able to dump the solution in the sewage line (call your sewage treatment facility) and you certainly can’t dump the solution on the ground or in a storm drain. You can separate the oil and solid contaminants from the solution so that the cleaning solution can last for an indefinite period.

Maintenance

Do not allow the sludge accumulation in the tank to exceed a 1″ depth. Otherwise, the sludge build-up could damage the heating elements) and pump. Depending on the application, some businesses have to clean out the sludge weekly, while others can go months before cleaning out the tank. Since you can’t see the sludge, clean out the tank within the first week of operation and develop an appropriate clean out schedule.

The following procedure should be followed for sludge removal:

• Disconnect all power to the machine or make sure all breakers are in the off position.
• Remove the wash rack and filter basket from the machine.
• Using the drain, remove the solution from the tank. You can save the solution for reuse.
• Scrape out the sludge through the filter basket opening being careful to not hit the heating element.
• Close the drain and install the filter Basket and wash rack.
• Fill tank with solution to proper level. If spray nozzles become clogged you may need to flush the spray tubes. Remove all pipe caps and bottom spray nozzles and run a maximum of 60-second wash cycle.

CAUTION

When flushing the spray tubes, running a wash cycle longer than 60 seconds could damage the pump motor.

Follow daily and monthly maintenance guidelines included in this manual.
