Coupling Connection Instructions

Coupling Assembly Details

1.Remove the protector caps and plugs. Wipe the seats and threaded surfaces with a clean cloth to remove any possible foreign matter.

2.Thoroughly lubricate the threads, o-rings, diaphragms and all internal coupling surfaces with polyolester refrigerant oil. Failure to lubricate could cause a false sense of tightness and a leak will result from the incomplete assembly.

Note: Scotsman line sets include lubricant packets.

3. Position the fittings on the correct connections on the condenser and ice machine.

4a. Begin to tighten the couplings together by hand. Continue to turn the swivel nuts by hand until it is certain that the threads are properly engaged.

4b. Using two wrenches, one to rotate the swivel nut and one to hold the tubing in place, tighten each coupling.

It is CRITICAL that ONLY the NUT on the pre-charged tube be turned, or the diaphragms will be torn by the piercing knives and become loose in the refrigeration system causing severe operational problems.

Note: As the coupling is tightened, the diaphragms in the quick connect couplings will begin to be pierced. As that happens, there will be increased resistance to tightening the swivel nut.

4c. Continue tightening the swivel nut until it bottoms out or a very definite increase in resistance is felt (no threads should be showing). Do NOT overtighten.

5.Use a marker or pen to mark a line on the coupling nut and unit panel. Then tighten the coupling nut an additional one-quarter turn. The line will show the amount that the nut turns.

Note: The final 1/4 turn forces two shoulders on the swivel nut end into the beveled surface of the male end, resulting in a sealed brass-to-brass connection.

6.After all connections have been made check the couplings for leaks.

Flaked ice, on the other hand, is popular in seafood displays and salad bars because of its ability to conform to the shape of the items being displayed, ensuring optimum presentation and longevity of freshness. Gourmet ice, known for its clarity and slow melting rate, is often used in high-end establishments to enhance the overall drink experience.

Scotsman's commitment to energy efficiency is another significant characteristic of their products. Many of Scotsman's ice machines are designed with eco-friendly features, such as heavy insulation and high-efficiency compressors. This not only reduces energy consumption and operating costs but also helps businesses contribute to environmental sustainability.

The innovative technology utilized in Scotsman machines includes advanced water and air filtration systems, which ensure the production of clean, clear ice while minimizing maintenance requirements. Moreover, the use of a unique ice production system allows for faster ice-making cycles, enabling establishments to keep up with high-demand periods seamlessly.

Scotsman also prioritizes user-friendliness in their design. Many models come with intuitive controls, allowing for easy operation and monitoring. Additionally, robust construction and durable materials ensure longevity, minimizing downtime and repair costs for users.
