Installation

Selection of installation location

Put the portable air conditioner in a flat location where the air outlets cannot be covered up, place the unit no less than 20 in. (50cm) away from a wall or other obstacle.

Mounting the exhaust hose

1)Fix the square end of the exhaust hose to the exhaust terminal of the unit as shown.

2)Put the other end (discharge) to the nearest window.

Note: The length of the air exhaust hose is between 24" - 72". Try to keep the hose as straight and horizontal as possible.

Instructions to install hose

If the hose becomes disconnected from the hose fitting it must be reinserted. Fit the hose to the hose fitting then rotate it 2 - 3 revo- lutions to tighten the hose into the fitting. See figure below:

Correct mounting shown below

(If mounting in the wall, the height of the hole should be 16" - 51")

P-12 specifications

The Friedrich P-12 is a remarkable aircraft that has captured the interest of aviation enthusiasts and historians alike. Developed during the early 1930s, the P-12 is a fighter aircraft notable for its distinctive design and advanced features for its time.

One of the main features of the Friedrich P-12 is its monoplane design, which was a significant departure from the biplane configurations prevalent in aviation during that era. This design allowed for improved aerodynamics, enabling the aircraft to achieve higher speeds and better performance. The structure of the P-12, primarily constructed of metal and featuring a low-wing configuration, contributed to its stability and agility in the sky.

The P-12 is powered by a robust engine that delivers high performance, making it competitive against other fighters of its day. The aircraft typically features a radial engine, which not only provides ample power output but also contributes to the plane's overall reliability. Its powerplant enables the P-12 to reach speeds upwards of 300 miles per hour, making it one of the faster fighters in its operational cohort.

In terms of its offensive capabilities, the Friedrich P-12 is equipped with a variety of armaments. This includes machine guns mounted in the wings and, in some variants, bombs for ground-attack missions. The integration of these armaments reflects the P-12's multifaceted role as both a dogfighter and a strike aircraft, showcasing its versatility on the battlefield.

Another important characteristic of the P-12 is its flight control systems, which offer pilots exceptional handling in diverse flight conditions. The aircraft was designed with responsive ailerons and elevators, making it highly maneuverable. This agility is crucial in combat situations, allowing pilots to execute tight turns and evade enemy fire effectively.

Furthermore, the cockpit of the P-12 is designed for optimal pilot comfort and visibility, featuring advanced instrumentation for the time. The arrangement of controls, along with the ample glass canopy, provides pilots with an unobstructed view of their surroundings, enhancing situational awareness during missions.

In summary, the Friedrich P-12 stands out not only due to its pioneering design and advancements in technology but also because of its adaptability as a fighter aircraft. Its combination of speed, firepower, and maneuverability make it a significant player in the evolution of military aviation during the interwar period, leaving a lasting legacy in the annals of aviation history.
