Requirements for Detergents and Sanitizers Detergents Remember, improper detergents may damage equipment! Use of the correct detergent in your Power Soak system is critical to its washing performance. If you are having problems with cleaning results, please contact the factory. Your new system requires a low-foaming, metal/aluminum-safe detergent that is safe for the hands. The detergent should have good grease cutting abilities but not have an excessively high pH level.
Operating Instructions 7
Preparing the System Filling the System At the beginning of each day or shift, fill the sinks with water that is metered to approximately the correct operating temperatures: • • • Wash sink (115°F / 48°C) Rinse sink (75°F / 24°C) Sanitizer sink (75°F / 24°C) All sinks should be filled to, but not above, the “waterline” marks. Fill the wash sink (the sink with the water jets) with water that is approximately 115°F / 48°C.
Adding Detergents & Sanitizers Manual Chemical Dispensing After the sinks have been filled with water, add the proper amount of detergent and sanitizer. The detergent goes into the wash sink (the sink with the water jets) and the sanitizer goes into the sanitizer sink (the last sink). Be sure to add the proper amount of chemicals to each sink. The amount to be used should be provided by your chemical supplier. Do not add the detergent or sanitizer to the sink prior to or during filling.

Controls and Features Start Button (green) Starts the washing action and starts the timer. Your Power Soak sink will run for four hours after this button is pressed. Stop Button (red) Stops the washing action and resets the timer. Heat Switch (black on/off switch) Not on all models. Turns on power to the heat control. The heat control measures the water temperature and decides whether to heat the water more. Digital Display (heat control) Not visible on all models.
Controls and Features - Continued Starting and stopping the wash action To start the wash action, press the green “START” button. A strong “rolling” wash action should be present. To stop the wash action, press the red “STOP” button. Introducing Pots and Pans to the PowerSoak Dirty pots and pans should be brought to the Power Soak in a timely manner. Do not allow items to sit and air dry.
Controls and Features - Continued Loading and Using the Wash Sink The Power Soak is a “random loading” system. This means that Power Soak items are not racked for washing. Instead, they are randomly loaded one at a time. As items are brought to the system and scrapped, they should be immediately dropped into the wash sink. If there is no movement of items in the wash sink, or if items are stationary above the waterline, the system has been overloaded and some items must be removed.
13 Controls & Features - Continued Loading and Washing Utensils Each Power Soak system comes with a utensil basket that hangs in the wash sink. All utensils and other small wares should be loaded into and washed inside this basket. Do not wash knives or other sharp objects in the Power Soak. Doing so may cause bodily injury. Unloading the Wash Sink The employee responsible for pot washing should routinely pass by the Power Soak and remove clean items from the wash sink.
14 Controls & Features - Continued Rinsing Pots and Pans Clean items that have been removed from the wash sink should be thoroughly rinsed. This is achieved by spraying them off or dipping them in the rinse sink (center). It is important that any remaining detergent residue is removed from the items prior to sanitizing. If items are rinsed by the "dipping" method, it is important to keep the water "fresh" by frequently draining and filling the rinse sink.
15 Controls & Features - Continued Deep Cleaning and "Night Washing" Extremely soiled items and pieces of cooking equipment that require regular, intensive cleaning can be washed in the Power Soak system overnight. Load the items to be deep cleaned into the Power Soak' s wash sink, turn the system on and leave it running overnight.
Preventive Maintenance Your system requires minimal, routine preventive maintenance. As such, the following should be done on a routine basis to ensure that your system remains reliable: Daily Clean the liquid level sensors. These sensors are located on the side walls of the wash and sanitizer tanks. They are the white plastic discs with metal centers. Clean the sensor faces thoroughly. If cleaned regularly, a washcloth and soapy water are all that is required.

Component Operation and Checks The following checks should only be performed by qualified technicians using extreme caution. Electrical hazard to untrained personnel may result in electrical shock, burns, or death. Heater Contactor If there is 208v-230v across the coil and the contactor does not pull in, the contactor is defective. If there is 208v-230v across terminals L1 and L2 and the contactor is pulled in, but no voltage across terminals T1 and T2, the contactor is defective.
Component Operation and Checks Liquid Level Control and Sensor The liquid level control sends a trickle current (1/1000 amp) out terminal 5 to the liquid level sensor. If there is water in the wash sink, the current passes through it to the wash sink wall and back to the liquid level sensor to terminal 6. On some machines, the wire from terminal 6 is hooked up to a second probe instead of the wash sink wall. Reversing these 2 wires will not affect the operation.
Component Operation and Checks Timer The timer controls how long the pump will run after the "start" push button is pushed in. Two different timers have been used. They function the same but the settings differ. The timer settings should be as follows: MODE RANGE FACE NUMBERS DIAL SETTING OS HRS 0 through 5 4 When the "start" push button is pushed, the timer is activated and sends L1 power to terminal A1 on the motor starter/overload. The timer can be checked as follows: 1.
Component Operation and Checks Pump Contactor The thermal overload can be checked as follows: 1. If there is 208-230v across the coil (terminals A1 and A2) and the contactor does not pull in, the contactor is defective. 2. TURN POWER OFF AT BREAKER PANEL. 3. Remove the wires from terminals T1 and T3 on the thermal overload. 4. Push the contactor closed manually and check for continuity across pump contactor terminals L1 and T1, L2 and T2, L3 and T3.
