This document provides installation and start-up instructions for the Vogt HE S Series Tube-Ice Machine, a device designed to produce tube ice.

Function Description:

The Vogt HE S Series Tube-Ice Machine is an industrial appliance that produces tube ice. The machine operates by circulating water through a system where it freezes into tubes, which are then harvested. It is designed for commercial and industrial applications requiring a continuous supply of tube ice. The machine's operation involves a refrigeration cycle, water circulation, and an ice harvesting mechanism. It can be configured for air-cooled or water-cooled condenser systems, and also offers options for single or dual ice production (cylinder or crushed ice).

Important Technical Specifications:

Usage Features:

Bin Installation: The machine is designed to be set on a solid, level bin top. Minor leveling adjustments can be made using leveling screws. The ice storage bin dimensions are critical for proper installation, with specific minimum and maximum chute opening measurements.
Lifting Methods: The manual outlines two methods for lifting and setting the machine onto an ice storage bin: the Forklift-&-Blocks Method and the Forklift-&-Rope or Lifting Straps Method. Both methods require adequate load-carrying capacity and specific equipment (forklift, wooden blocks, ropes/straps).
Condenser Options: The machine can be connected to air-cooled or water-cooled condensers. Air-cooled condensers can be installed vertically or horizontally.
Ice Bin Thermostat Sensor: The machine is equipped with an electronic ice bin thermostat to ensure proper protection. The sensor determines when the bin is full and stops the machine. It can be configured for cylinder ice, crushed ice, or dual ice machines.
Programming the Electronic Bin Thermostat: The thermostat has an LCD readout and can be programmed to shut down the machine at 38°F and restart at 40°F. The lockout switch is located inside the control panel.
Automatic Blowdown/Petcock: This feature helps maintain water quality by periodically flushing the water tank. It is designed to reduce the necessity for frequent flushing or cleaning.
Adjustable Blowdown: This feature allows for manual adjustment of the blowdown frequency and duration, which helps in managing water quality and reducing mineral buildup.
Dual Pumpdown Mode: This mode is initiated by setting the selector switch to "Clean" position. It is used to clear the refrigerant from the freezer and condenser.
Adding Refrigerant: Specific instructions are provided for adding refrigerant, including connecting to the charging valve and monitoring the sight glass.
Casing Installation: Detailed steps are provided for installing the stainless steel casings, ensuring proper fit and alignment.

Maintenance Features:

Regular Checks: The manual emphasizes regular checks for leaks, electrical supply, water supply, and drain connections.
Compressor Maintenance: The scroll compressor is phase sensitive, and its rotation must be checked. Failure to do so may affect compressor warranty. The crankcase heater must be energized for a minimum of 2 hours before attempting to operate the compressor.
Water Quality: The automatic blowdown/petcock feature helps maintain water quality and reduce mineral buildup, which is crucial for the machine's longevity and ice quality.
Refrigerant Management: Instructions for adding refrigerant and ensuring proper charge are provided. It is critical to follow all local and federal regulations regarding the handling of refrigerants.
Troubleshooting: The manual includes a section on troubleshooting, with a table of PLC inputs, outputs, and fault codes to help diagnose common issues. It also outlines Copelend Performance Alert (CPA) system conditions and their descriptions.
Warranty Registration/Start-Up Form: An important notice states that the warranty registration/start-up form must be completed and returned to Vogt Tube-Ice® to initiate and assure a full warranty. This form also serves as a checklist for initial setup and verification of proper installation.
Freezer Pressure Switch (FPS2) Adjustment: The pressure switch can be adjusted to set the differential for recommended ice weights, which is important for controlling the ice production process.
Cleaning Cycle: The "Clean" position on the selector switch initiates a dual pumpdown mode, which helps in maintaining the system.
