Install the indoor unit more than 3.3' (1 m) away from any antenna or power lines or connecting wires used for tele- vision, radio, telephone, security system, or intercom.

Electrical noise from any of these sources may affect operation.

*If total tubing length becomes 150 to 200 ft. (Max.) or 150 to 230 ft. (Max.), charge additional refrigerant (R410A) by 0.22 oz./ft. No additional charge of compressor oil is necessary.

2-2. Embedding the Tubing and Wiring

Before beginning embedding installation work, consult fully with agencies or offices related to the building’s foundation, construction, electricity, and water.

Wait to make connections to the embedded portion. Each connection step is described later in this manual.

Securely cover the end of the embedded tubing to prevent intrusion of dirt or moisture.

If an embedded tube is to be left for a long time, fill the tube with nitrogen and seal both ends securely.

If a tube is left open for an extended time, moisture in the air inside the tubing may condense into water droplets, and lead to water contamination of the refrig- erant circuit.

In order to prevent insulation breakdown and ground faults, do not allow wiring ends to come in contact with rainwater, or be subjected to condensation or dew.

Apply sufficient thermal insulation to the refrigerant tubing and drain pipes.

The KMHS2472, known for its larger capacity, is designed to accommodate family-sized meals with ease. It boasts a spacious interior that allows for larger dishes, making it ideal for Sunday roasts or holiday gatherings. Its sensor cooking options automatically adjust cooking times and power levels based on the moisture released from the food, optimizing results every time.

On the other hand, the KMHS1272 is the mid-range model, striking a perfect balance between size and functionality. It features multiple cooking presets, which streamline meal preparation by allowing users to select one-touch options for commonly microwaved items. This makes it an excellent choice for busy households looking for convenience without compromising quality.

The KMHS1872, while still maintaining a good capacity, focuses on energy efficiency, making it suitable for eco-conscious consumers. This model includes an eco mode that reduces energy consumption during standby, contributing to lower utility bills while still providing the high performance expected from the Sanyo brand.

All models are equipped with advanced safety features, such as a child lock, preventing accidental operation and ensuring peace of mind in households with young children. The stainless steel finish adds a modern touch to any kitchen, while the easy-to-clean interior enhances usability.

In summary, the Sanyo KMHS2472, KMHS1272, and KMHS1872 are not just standard microwaves; they are an investment in convenience and quality cooking.
