Safety Precautions

Installation Manual 3

ENGLISH

■ Installation

Safety Precautions

To prevent injury to the user or other people and property damage, the following instructions must be followed.

■ Incorrect operation due to ignoring instruction will cause harm or damage. The seriousness is classified by the following indications.

WARNING

CAUTION

This symbol indicates the possibility of death or serious injury.

This symbol indicates the possibility of injury or damage.

Be sure not to do.

Be sure to follow the instruction.

WARNING

Do not use the existing manifold gauge for R22 refrigerant.

• To charge the refrigerant stably, always

use the manifold gauge for high pressure (R410A).

Install the air conditioner at a designated location using the designated material.

• Heat exchanger inlet/outlet pipe location.

Do not store or use flammable gas or volatile substance near the air conditioner.

• It can cause a fire or problem

to the product.

Do not mix existing R22 pipe and installation products for the installation.

• When you mix the mineral oil of R22 and R410A oil (PVE), it can decompose with water to cause problems to the product.

Do not mix other refrigerant with the designated refrigerant (R410A) during the installation or moving the air conditioner.

• When other refrigerant is mixed with the original refrigerant, it can cause a problem in the refrigerant cycle and damage the product.

System air conditioner can only be installed by specialized service provider with air condition installation certifications.

• Inappropriate installation can cause leakage, fire and electric shock.

When moving or reinstalling the air conditioner, please contact the

MULTI VTM AHU

installation service provider.

• Inappropriate installation can cause leakage, fire and electric shock.

Do not disassemble, repair or reconfigure the product arbitrarily.

• It can cause a fire and electric shock.

Safety Precautions

4 AHU CONTROL KIT

■ Operation

■ Installation

Do not install the air conditioner outdoors.

• If installed outdoor inevitably, consult Multi

VTM

AHU installation service provider.

Do not let any worker or user climb on top of the product.

• The person can get seriously injured.

Make sure that water does not get inside the product (Controller). Especially, do not clean the product with water.

• It can cause electric shock and problems.

When the air conditioner is submersed in water, always consult

MULTI VTM AHU

installation service provider.

• It can cause a fire and electric shock.

Do not keep any heating devices near the product.

• It can cause a fire.

After the product installation and repair, always check for gas leakage.

• It can cause problems in the product.

When installing the product, always make sure to level to the product.

• It can cause vibration and leakage.

Do not install the product where flammable gas leaks.

• It can cause a fire and problems to the product.

■ Operation

If the refrigerant leaked while installing the product, always ventilate the room.

• The refrigerant gas can react with the fire to turn into hazardous gas to cause an accident.
