• HRV • VKM-GA(M)V1 10 Outdoor Air Processing of Ceiling Mounted Duct Connection Type The structure of VKM-GAMV1 model is different from other ventilation models. Points you need to note are summarized below, which please use for your reference when selecting the model. 10.1 Stand-alone Operation is Possible as an Independent System Because no function to control the room temperature is equipped, only the operation mode (cooling, heating, automatic, ventilation) is displayed on the remote controller.
Page 250: Central Control System
• HRV • VKM-GA(M)V1 [Points to be noted for VKM-GA(M)] There are following restrictions with VKM-GA(M) model due to its own controlling structure. 1. Stand alone system: No address setting is required because of its automatic addressing function (corresponding multiple type for building P-board : Master). Because it is under a group control, it is always required to connect to a remote controller.
Page 251: Restrictions To Control System
• HRV • VKM-GA(M)V1 • Structure without a remote controller cannot be accepted because the remote controller group is controlled within a VKM-GA(M) model.

• HRV • VKM-GA(M)V1 11 Appendix 11.1 Purpose of Ventilation Living environment, and working environment as well, can be polluted for various reasons, which in turn will lead to hygienic problems and/or lower productivity. To avoid this, the polluted air must be replaced with fresh air.
Page 254 • HRV • VKM-GA(M)V1 Tobacco Only one cigarette can soon pollute the air in the enclosed room. And both the smoker and other non- smokers staying here are affected. Especially the “secondhand” smoke from the tip of cigarette contains 2~3 times larger amount of harmful substances (nicotine and tar) than the “main smoke” exhaled by the smoker, so that the non-smokers around the smoker can be affected by tobacco smoke.

Page 260 • HRV • VKM-GA(M)V1 11.2.3 Mechanical Fan Types and their Characteristics Axial fan and centrifugal fan Ventilation fan are roughly classified into two types: axial fans and centrifugal fans. These two types of ventilation fans are selected depending on the operating conditions and/or application. Axial fan is normally a propeller fan available for applications for larger flow but at smaller pressure rating ranging between 0 and 30 Pa.
Page 261 • HRV • VKM-GA(M)V1 11.2.4 Operating Sound As well as the required airflow and static pressure, the operating sound (noise level) is an important factor for determining the type of ventilating fans.
