Ι . Overview 1. DVM system series 1-1. What is DVM? The DVM(Digital Variable Multi) air conditioning system is operated by a variable-capacity compressor and is accommodated by multiple evaporators (indoor units). It is touted as the next-generation modular system in the world of high-efficiency air conditioning. lt has undoubtedly changed the face of cooling associated with high-storied buildings.
1-2. Features of DVM (1) Customized air conditioner 1) Up to 16 indoor units can be connected to one outdoor unit. 2) Indoor units can be combined by various methods, according to each room’s use and shape. 3) There are several indoor units which can be applied; 1-way cassette type, 4-way cassette type, Ceiling, Duct (Low silhouette, Built-in, High pressure), Wall-mounted and Floor standing type.
Page 7
Ι . Overview 1. DVM system series (3) Variable compressor The world’s first PWM(Pulse Width Modulation) compressor controls the cooling & heating capacity automatically, depending on the load. 1) Principle of the digital compressor Composition The solenoid valve is installed for the compressor´s loading / unloading between the upper part of the fixed scroll and the suction pipe.
Page 8
2) PWM (Pulse Width Modulation) valve PWM valve is the valve to take away the fixed scroll by lifting up through the difference of pressure after the digital scroll compress being connected to the outlet and inlet of suction. Therefore, the capacity of compressor is controlled automatically according to the operation status such as loading when the valve is closed or unloading when the valve is opened.

9-3. Recovery of refrigerant (1) Close the service valve of liquid side and then press the refrigerant recovery button on outdoor PCB (2) When the low pressure is getting lower enough, close the service valve to press the refrigerant recovery button again or press key 3. Pressing the button stops the compressor.
. Installation 10. Testing operation Cautions for operation Put the power 6 hours before initial operation so that the crank case heater may be heated. When doing the retry of initial operation after main power off, start the operation 2 and half hours after power on. If the heater is not heated, the operation can not be started for 2 hours after power on for the protection of compressor.
(8) If the preheating of compressor is completed, the communication is performed between indoor unit connected and options. It is the normal at the time when the address on the right display is shown as many as shown on the left side display. (9) Check through the PC connected with outdoor unit whether the data is correct from temperature sensor and electronic expansion valve.

. Installation 11. Cautions for refrigerant leaks 11-1. Introduction The DVM system, like most other air conditioning systems, uses R-22 as its refrigerant. R-22 itself is an entirely safe non-toxic, non-combustible refrigerant but care must nevertheless be taken to ensure that the air conditioning facilities are installed in a room which is sufficiently large to avoid a *dangerous concentration of refrigerant gas in the unlikely event of a serious leak in the system.

11-2. Procedure for checking dangerous Concentration Check the dangerous concentration in accordance with steps 1~4 below and take whatever action is necessary. (1) Calculate the amount of refrigerant(kg) charged to each system separately. (Amount of refrigerant in a Total amount of refrigerant(kg) (Additional charging amount) = single indoor unit system) in the system...

(4) Dealing with situations where the result exceeds the dangerous concentration level. Where the installation of a facility results in a concentration in excess of the dangerous concentration level then it may be necessary to revise the system design to some extent or else take one of the fol- lowing courses of action: <Action 1>...
