Electric Hook-up

Installation (cont.)

The brewer is designed to operate at the specified voltage on the nameplate with a tolerance of ± 10% for voltage deviation. It is very important that the power line to the brewer be checked to make sure that the voltage is within 10% of the brewer’s rated voltage. Failure to provide adequate voltage, as defined above, will cause problems with your brewer. If the power is too low, the solenoid valves may or may not work or longer recovery time will be experienced. The brewer may be permanently damaged if the voltage is too high.

1)The electric ratings for your brewer are printed on its nameplate.

2)The brewer should be connected to its own circuit with a fused disconnect switch or a circuit breaker near the brewer.

Important: For CE units, means shall be provided to endure all pole disconnection from the supply. Such means shall be

one of the following: a supply cord fitted with plug, or a switch that is directly connected to the supply terminals and has a contact separation of at least 3mm in each pole.

3)Attach the appropriately sized cord to the brewer with a cord grip for the 1 1/2” (3.8 cm) electric input opening. The cord may enter through the rear or bottom on the left side of the brewer. Use an oil resistant cord such as type SO, SOO, SAO, STOO, SEO, SJO, SJOO, SJTO, SJTOO, SJEO, HSO, HSOO, HSJO, or HSJOO.

Alternatively, flexible conduit and type THHN wires may be used. Use only copper conductors.

4)Standard connection is 1 phase 3 wire. Connect the two lines to L1 and L2 on the terminal block. If the brewer is wired for three phase, a lug, L3, is provided on the terminal block. Neutral line should be connected to the N terminal. Alternately, if no neutral is available, the brewer can be wired accordingly by connecting L1 to position marked “L1” and L2 to position marked “L2”. This will require the installer to change the connection to the transformer primary from the white wire (120V) to the blue (208V) or orange (230,240V) connection. See below.

NOTE: This “no neutral” conversion is only applicable to units marked as 208V, 230V, or 240V. It is NOT applicable to units marked 120/208V or 120/240V.

Note: The brewer utilizes a multiple tap primary transformer to convert line voltage to 24 volts for use by the controller and some operating controls. The transformer has taps for 120V (white wire), 208V (blue wire), and 240V (orange wire) line voltage. Be sure to connect the white wire from the terminal block to the proper tap for the supplied voltage.

See diagram below.

5) The body of the brewer must be grounded. A ground lug is provided for this purpose.

Note: If supply cord is damaged, it must be replaced by a special cord or assembly from the manufacturer, or it’s service agent.

Note: This appliance is IP10 rated, and shall not be cleaned with a water jet.

WARNING

Never use the ground conductor as a neutral. This could cause electrocution.

APB-430V2E230, APBIC-330V2E230, APB-430V2, APBIC-330V2, APBVSA-430V2E230 specifications

Grindmaster’s lineup of commercial coffee brewing systems, including the APBVSA-330V2, APBIC-330V2, APBIC-430V2, APBVSA-430V2, and APB-430V2, is designed to meet the demands of high-volume coffee setups, offering a blend of efficiency, precision, and technology. These models are tailored for establishments such as cafes, restaurants, and convenience stores, where quality coffee is essential.

A prominent feature across these models is the advanced digital control system that ensures precise brewing temperatures and times. This technology is crucial for extracting the optimal flavor from coffee grounds. User-friendly touchscreen interfaces allow baristas to easily adjust settings, making these machines accessible even for less experienced staff.

The APBVSA (Auto Programmable Batching Variable Speed Appliances) series includes the APBVSA-330V2 and APBVSA-430V2, both known for their high-capacity brewing capabilities. They are equipped with variable speed pumps that enhance coffee extraction consistency. This feature is vital for operations that demand a steady volume of brew while maintaining high-quality standards. These models also incorporate brewing profiles that can be programmed to suit different types of coffee, allowing for customization based on customer preferences.

In contrast, the APBIC (Auto Programmable Batch Instant Coffee) versions, such as the APBIC-330V2 and APBIC-430V2, focus on instant coffee solutions. These machines provide an equally efficient service but are optimized for businesses that may not require the full range of brewing capacities. They offer quick brewing cycles and maintain a compact design, making them ideal for establishments with limited space.

The APB-430V2 represents a balance between capacity and versatility. This model features a dual brewing system allowing for simultaneous brewing of different coffee types, catering to diverse customer preferences effectively. The innovative thermal carafes that are often included with these models help maintain ideal serving temperatures without the risk of overbrewing.

All models feature robust construction and durable materials, ensuring longevity even in the busiest environments. Additionally, their energy-efficient systems are designed to reduce power consumption, appealing to environmentally conscious businesses.

In summary, the Grindmaster APB series combines technology with user-friendly operation, catering to the growing demand for high-quality, batch-brewed coffee in commercial settings. With their advanced features, each model serves a unique purpose, allowing businesses flexibility in meeting customer demands while optimizing their brewing operations.
