Sanyo SAP-KRV94EHDX 用户手册

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.
