Sanyo CL2472 Manual Do Utilizador

This air conditioning system meets strict safety and operating 

standards. As the installer or service person, it is an 

important part of your job to install or service the system so it 

operates safely and efficiently.

Carefully read this instruction booklet before beginning.

Follow each installation or repair step exactly as shown.

Observe all local, state, and national electrical codes.

Pay close attention to all warning and caution notices given 

in this manual.

These instructions are all you need for most installation 

sites and maintenance conditions. If you require help for 

a special problem, contact our sales/service outlet or 

your certified dealer for additional instructions.

The manufacturer shall in no way be responsible for 

improper installation or maintenance service, including 

failure to follow the instructions in this document. 

Do not supply power to the unit until all wiring and tubing 

are completed or reconnected and checked.

Highly dangerous electrical voltages are used in this 

system. Carefully refer to the wiring diagram and these 

instructions when wiring. Improper connections and 

inadequate grounding can cause accidental injury or death.

Ground the unit following local electrical codes.

Connect all wiring tightly. Loose wiring may cause 

overheating at connection points and a possible fire 

hazard.

Be careful when picking up and moving the indoor and 

outdoor units. Get a partner to help, and bend your knees 

when lifting to reduce strain on your back. Sharp edges or thin 

aluminum fins on the air conditioner can cut your fingers. 

Make sure the ceiling/wall is strong enough to hold the unit’s 

weight. It may be necessary to construct a strong wood or 

metal frame to provide added support.

Properly insulate any tubing run inside a room to prevent 

"sweating" that can cause dripping and water damage to walls 

and floors.

Use a raised concrete pad or concrete blocks to provide a 

solid, level foundation for the outdoor unit. This prevents water 

damage and abnormal vibration.

Securely anchor the outdoor unit down with bolts and a metal 

frame. Provide a suitable air baffle. 

Install the outdoor unit on a raised platform that is higher than 

drifting snow. Provide snow vents.

Use the flare method for connecting tubing.

Apply refrigerant lubricant to the matching surfaces of the 

flare and union tubes before connecting them, then tighten 

the nut with a torque wrench for a leak-free connection.

Check carefully for leaks before starting the test run.

Turn the power off at the main power box (mains) before 

opening the unit to check or repair electrical parts and 

wiring.

Keep your fingers and clothing away from any moving parts.

Clean up the site after you finish, remembering to check 

that no metal scraps or bits of wiring have been left inside 

the unit being serviced.

Ventilate any enclosed areas when installing or testing the 

refrigeration system. Escaped refrigerant gas, on contact 

with fire or heat, can produce dangerously toxic gas. 

Confirm upon completing installation that no refrigerant gas 

is leaking. If escaped gas comes in contact with a stove, 

gas water heater, electric room heater or other heat source, 

it can produce dangerously toxic gas.
