The WAREFORCE UH30-FND/UL30 is an undercounter dishmachine series, designed for commercial use. This manual provides comprehensive installation, operation, and service instructions for both high-temperature (UH30-FND) and low-temperature (UL30) models.
Function Description:
The WAREFORCE UH30-FND is a high-temperature, hot-water sanitizing undercounter dishmachine equipped with a booster tank and chemical feeder pumps for detergent and rinse-aid. It is designed to efficiently clean and sanitize dishes using high temperatures.
The WAREFORCE UL30 is a low-temperature, chemical-sanitizing undercounter dishmachine featuring a wash tank heater and chemical feeder pumps for detergent, rinse-aid, and sanitizer. This model focuses on chemical sanitization at lower temperatures.

Usage Features:
- Chemical Feeder Pumps: Both models come with chemical feeder pumps. The UH30-FND includes detergent and rinse-aid pumps, while the UL30 adds a sanitizer pump.
- Priming Chemical Feeder Pumps: Instructions are provided for priming the chemical feeder pumps during initial installation or after chemical line removal. The UH30-FND priming cycle defaults to 70 seconds for detergent and 180 seconds for rinse-aid. UL30 requires holding prime switches until chemicals are visible in the wash tank.
- Programming Chemical Feeder Pumps (UL30): The UL30 model allows for programming chemical amounts using a universal timer on the control panel. This feature enables adjustment of detergent, rinse-aid, and sanitizer dispensing times.
- Operational Modes: The machines offer various cycle options, including Normal, Extra Heavy, Heavy, and Delime.
- Easy-to-Use Controls: The UH30-FND features a digital display with cycle buttons for selecting modes and adjusting setpoints. The UL30 has a control panel with switches and a thermometer.
- Initial Fill Procedure: Specific instructions are provided for the initial filling of the wash tub, including waiting for the wash temperature to reach the minimum required level before operation.
- Ware Preparation Guidance: Emphasizes the importance of properly preparing ware (removing scraps, placing cups upside-down) for optimal cleaning and sanitization.
Maintenance Features:
- Preventative Maintenance: The manual stresses the importance of regular preventative maintenance by qualified service personnel to ensure efficient operation and extend machine lifespan.
- Strainer Inspection and Cleaning: Operators are instructed to regularly inspect and clean the strainer to prevent clogging, which can reduce washing capability.
- Wash and Rinse Arm Maintenance: Detailed steps are provided for unscrewing, flushing, and cleaning wash and rinse arms, including removing end-caps and using a brush or toothpick for nozzles.
- Deliming Procedure: Comprehensive instructions for deliming both UH30-FND and UL30 models are included. This involves removing rinse arms, adding deliming solution, and running a delime cycle, followed by normal cycles to remove residual solution.
- Water Hardness Test: A water hardness test is required during installation. If hardness exceeds 3 GPG, a water softener or optional Scale Prevention System (SPS) is recommended.
- Troubleshooting Guide: A detailed troubleshooting section helps identify and resolve common issues, including fault codes (F1-F17 for UH30-FND) and general observations like water overflow, wash motor malfunctions, and temperature problems.
- Adjustable Setpoints (UH30-FND): The UH30-FND allows adjustment of rinse temperature, drain time, detergent time, rinse-aid time, detergent priming time, rinse-aid priming time, and temperature scale through a programming mode.
- Thermostat Settings: Thermostats are factory-set and should only be adjusted by an authorized service agent.
- Technical Support: The manufacturer provides technical support via a toll-free number for service personnel.
