The Micro Matic Pro-Line E-Series Refrigeration unit is a commercial-grade refrigeration system designed for dispensing beverages, primarily beer, and for back bar storage. This user manual and setup guide provides comprehensive information for safe and proper handling, installation, operation, and maintenance of the equipment.

Function Description:

The Pro-Line E-Series Refrigeration units are engineered to maintain keg temperatures within an optimal range of 34°F to 38°F (1.1°C to 3.3°C). They come in two primary configurations: Direct Draw Models and Back Bar Models. Direct Draw models are equipped with draft towers and faucets for dispensing beverages directly from kegs, while Back Bar models are designed for refrigerated storage, often featuring shelves and rails for various keg sizes or bottled beverages. The units integrate a refrigeration system that includes a compressor, condenser coil, and evaporator fan to ensure consistent cooling. Some models feature an air channel and draft tower system to deliver cold air directly to the beer towers, ensuring the beer remains cold from the keg to the faucet.

Horsepower (HP): Compressor horsepower ranges from 1/6 HP to 1/3 HP.
Amperage (AMP): Amperage draw varies from 2.5 to 6.5 AMP.
Refrigerant: All units use R-134 A refrigerant, with charge amounts ranging from 5.3 oz to 9.8 oz.
Voltage: All models operate on 115V 60Hz.
BTU: Cooling capacity ranges from 850 BTU to 2400 BTU.
Dimensions: Lengths vary from 17.5" to 95.5", widths are consistently 29.5", and heights are either 38" or 40.5".
Crated Weight: Weights range from 138 lbs to 406 lbs.
Temperature Control: Units feature either a mechanical (analog) or electronic (digital) temperature control system.

Usage Features:

The Pro-Line E-Series units are designed for ease of use and optimal beverage quality.

Installation: The manual provides detailed instructions for uncrating, sealing the base to the floor (if required by sanitation codes), and proper placement to ensure good air circulation. It emphasizes allowing the unit to stand upright for 24 hours if laid down during transport before plugging it in.
Tapping Instructions: Specific steps are provided for tapping D-Style valve kegs, including connecting gas and beer lines, aligning the coupler, and setting recommended pressure (12-14 lbs for domestic ales and lagers).
Temperature Control:
- Mechanical (Analog): Users can adjust the temperature using a knob located inside the cabinet. The factory recommends a specific setting (pointing to a yellow arrow) for optimal performance, with settings from "one" (warmest) to "seven" (coldest).
- Electronic (Digital): Models with digital controllers allow for precise temperature setting. Users can view and change the set point, with a minimum of 32°F (0°C) and a maximum of 40°F (4.4°C). The digital display also shows operational status and error codes.
Defrost: Mechanical thermostat models may require manual defrost by unplugging the unit for 15 minutes and leaving the door open. Electronic controller models feature an automatic defrost cycle every 6 hours, with an option for manual defrost by holding the defrost button for 5 seconds.
Shelving Installation: Instructions are provided for installing shelf rails and wire shelves, ensuring they are level and properly seated.
Draft Tower and Air Supply Hose Installation (DD Models): Detailed steps guide users through installing draft towers, including securing gaskets and bolts, and connecting the "COLD AIR HOSE" to ensure cold air circulation to the towers.

Maintenance Features:

Regular maintenance is crucial for the longevity and efficient operation of the Pro-Line E-Series units.

Stainless Steel Care and Cleaning: Recommendations include using soft cloths and alkaline or non-chloride cleaners to prevent damage to the protective film of the stainless steel. Routine cleaning with soap and water is advised, with non-abrasive cleaners for tougher stains. Acid-based cleaning solutions and certain food products should be avoided.
Condenser Coil Cleaning: This is a critical maintenance task, recommended every 30-60 days. The manual warns that neglecting this will void the compressor warranty. Cleaning methods include brushing for light dust, vacuuming or compressed air for heavier buildup, and de-greasing agents for heavy grease. It explicitly states not to use high-pressure water washes on electrical components.
Drain Maintenance: Each unit has an internal drain that removes condensation to an external evaporator pan. Users are advised to check the drain tube for disconnections or obstructions if excessive water accumulates inside or underneath the unit. Proper leveling of the unit is also important for effective drainage.
Troubleshooting Guide: A comprehensive troubleshooting section helps users diagnose and resolve common issues such as the unit not working, not reaching temperature, or water accumulation. This guide covers checks for power supply, thermostat settings, defrost cycles, door seals, fan operation, and drain pipe positioning.

The manual emphasizes safety first, with clear warnings about potential hazards and the importance of reading all instructions completely. It also provides contact information for customer service and warranty details, including a one-year parts and labor warranty and an additional four-year compressor part warranty.
