Cautions and Warnings

 Be sure to read the following safety cautions before conducting repair work. 

The caution items are classified into “ are especially important since they can lead to death or serious injury if they are not followed closely. The “ followed. Therefore, be sure to observe all the safety caution items described below.

About the pictograms

This symbol indicates an item for which caution must be exercised.

The pictogram shows the item to which attention must be paid.

This symbol indicates a prohibited action.

The prohibited item or action is shown inside or near the symbol.

This symbol indicates an action that must be taken, or an instruction.

Introduction SiE71-202

1.1.1 Cautions in Operation and Maintenance

WARNING

Never inspect or service the unit by yourself. Ask a qualified service person to perform this work. (The qualified service person) WARNING: Before obtaining access to terminal devices ( ), all power supply circuit must be interrupted.

OFF

Electric shock may result. Before servicing the unit, always shut off power.

WARNING

Do not change operations suddenly. It can result not only in malfunction but also failure of switches or relays in the body.

WARNING

Always use the air filter. If the air fitter is not used, heat exchange elements will be clogged, possibly causing poor performance and subsequent failure.

SiE71-202 Introduction

WARNING

• Place such as machinery plant and chemical plant where gas, which contains noxious gas or corrosive components of mate rials such as acid, alkali, orga nic solvent and paint, is generated. Place where combustible gas leakage is likely.

Such gas can cause fire.

Do not use a HRV or an air suction/discharge grille in the following places.

• Place subjected to high temperature or direct flame.

Avoid a place where the temperature near the HRV unit and the air suction/discharge air grille exceeds 50°C If the unit is used at high temperature, deformed air filter and heat exchange element or burned motor result.

50°C

• Place such as bathroom subjected to moisture.

Electric leak or electric shock and other failure can be caused.

• Place subjected to much carbon black.

Carbon black attaches to air filter and heat exchange element, marking them unable to use.

5. Indication of operation control method: When the operation of HRVs are linked with the air conditioners, this indication may be shown. While the indication is shown, the ON/OFF of HRVs cannot be operated by the HRV remote controller.

6. Indication of operation standby: It indicates the precooling/preheating operation. This unit is at stop and will start operation after the precooling/preheating operation is over. Precooling/preheating operation means the operation of HRVs is delayed during the startup operation of linked air conditioners such as before the office hours. During this period the cooling or heating load is reduced to bring the room temperature to the set temperature in a short time.

7. Indication of centralized control: When a remote controller for air conditioners or devices for centralized control are connected to the HRVs, this indication may show.
