This document is an installation manual for True Manufacturing Co., Inc.'s Open Air Merchandiser, providing comprehensive instructions for setup, operation, and maintenance.
The True Open Air Merchandiser is a commercial refrigerator designed for displaying products in an open-air environment, allowing easy access for customers. It is built to provide reliable and trouble-free operation for many years, maintaining optimal temperatures for stored goods. The manual emphasizes proper installation and maintenance to ensure efficient and successful operation, highlighting that the unit is manufactured under strict quality controls using high-quality materials.
The manual provides a detailed wire gauge chart for both 115 Volts and 230 Volts, indicating recommended wire gauges based on amperage and distance from the center load. For 115 Volts, wire gauges range from 14 AWG for short distances and low amps to 1 AWG for longer distances and higher amps. For 230 Volts, wire gauges range from 14 AWG to 1 AWG, similarly varying with distance and amperage.
Cabinet specifications include clearances: a 3" (77 mm) clearance is required at the rear of the cabinet and 8" (204 mm) clearance above the cabinet for proper ventilation. The recommended maximum ambient conditions are 75°F (24°C) and 55% relative humidity, or as indicated on the serial label. The IEC Shelf Weight Capacity is 47 lb/ft² (230 kg/m²).
Electrical connections are critical. The manual specifies NEMA plug configurations for 60 Hz use only: NEMA-5-15R (115/60/1), NEMA-14-20R (115/208-230/1), NEMA-5-20R (115/60/1), and NEMA-6-15R (208-230/60/1). It strictly prohibits the use of adapter plugs or extension cords, as these can void the warranty and pose safety hazards. Incoming voltage should be checked with a voltmeter to ensure it is within +/-5% of the rated voltage. The unit must be plugged into a dedicated electrical circuit.
Refrigerant safety information is provided, noting that units may use Hydrocarbon Refrigeration (R290). Warnings include risks of fire or explosion due to flammable refrigerants and insulation. Servicing should only be performed by trained personnel, and refrigerant tubing should not be punctured. Proper disposal of the cabinet is emphasized, requiring removal of doors and leaving shelves in place to prevent child entrapment.
The Open Air Merchandiser is designed for ease of use and product display. Shelving is adjustable to accommodate various customer applications. The manual provides detailed instructions for installing shelf brackets and shelves, ensuring proper air flow is not blocked by products. Products should not extend over the front edge of the shelves.
A night cover operation feature is included to conserve energy during overnight or extended off-peak business times. Users can pull the night cover toward the top of the product opening and secure its handle on a hook. To lower it, the handle is lifted off the hook, and the cover is gently guided down to retract into the product floor. A warning advises against releasing the handle until the cover is fully retracted.
The unit features an electronic temperature control and a light switch, with their approximate locations indicated in the manual. The light switch is typically in front of the top air flow honeycomb, and the electronic temperature control is behind or accessible through the front grill. The compressor is ready to operate upon purchase; users simply need to plug in the cooler. A 5-minute waiting period is recommended before restarting if the unit is disconnected or shut off. It is recommended to run the unit empty for 24 hours to verify proper operation before loading product.
Good airflow within the cabinet is critical, so products should not press against the sides or back wall, or come within 4" (101.6 mm) of the evaporator housing. Refrigerated air from the evaporator coil must circulate throughout the cabinet for even product temperatures.
Regular maintenance is crucial for the longevity and efficient operation of the unit. The manual provides detailed instructions for cleaning the condenser coil, which should be done every 30 days or as needed. Tools required include nut drivers (1/4" and 3/8"), a stiff bristle brush, compressed air, a vacuum cleaner, a flashlight, and eye protection. The process involves disconnecting power, removing the louvered grill, cleaning accumulated dirt from the condenser fins with a brush, and verifying cleanliness with a flashlight. If dirt remains, further steps involve removing condenser base bolts, rotating the condensing unit to access the drain hose fitting, gently blowing compressed air or CO2 through the coil, vacuuming the surrounding area, and then reassembling. The manual explicitly states that condenser cleaning is NOT covered by warranty.
Stainless steel care and cleaning instructions are provided, with warnings against using steel wool, abrasive, or chlorine-based products. It advises against cleaners with chlorides or phosphates. Recommended cleaning agents include white vinegar, ammonia, or commercial detergents with a soft cloth or sponge for routine cleaning. Stainless steel polishes and olive oil can help prevent fingerprints and smears. Degreasers are recommended for heavy grease or burnt-on foods. The manual also lists 8 tips to prevent rust on stainless steel, including maintaining cleanliness, using correct non-abrasive cleaning tools, cleaning along polishing lines, using alkaline/non-chloride cleaners, rinsing thoroughly, never using hydrochloric acid, treating hard water, and regularly restoring/passivating stainless steel.
Cabinet adjustments, servicing, and component replacement information are also included. Any adjustments should be made after the cabinet is level and properly supported. If condensate drain pans overfill, connecting them to a floor drain or installing optional electric heated condensate pans may be necessary. Instructions are given for routing excess condensation to a floor drain, which involves accessing the rear of the cabinet, removing the wire grill, connecting a vinyl hose to the 45° fitting on the condensate pan, routing the hose to the floor drain, and then reassembling.
For servicing and replacement, it is recommended to use OEM components and have a licensed service provider perform repairs to minimize risks. The unit should be unplugged before any cleaning or repairs. Setting temperature controls to "0" or powering off an electronic control may not remove power from all components (e.g., light circuits, perimeter heaters, evaporator fans).
The manual also provides contact information for True Manufacturing Service Departments in North America, Mexico, Latin America, UK/Ireland/Middle East/Africa/India, European Union/CIS, and Australia for warranty inquiries and technical support. Warranty information specifies a three-year parts and labor warranty, with an additional two-year HFC compressor warranty and four-year hydrocarbon compressor warranty, subject to specific conditions and exclusions. The warranty does not cover consequential damages, is not transferable, and does not cover issues arising from improper usage, installation, lack of maintenance, or use of non-OEM parts.
