9 3.2 Preparing the Location 1. Install the unit on a flat level surface to avoid tipping or shock. 2. The unit requires a minimum space more than 1.5m from a light and more than 20cm from the wall. 3. The floor should be level, and of solid construction to prevent any vibration or a noise. 4. Temperature at the location to be installed should be below 86F, 80%RH, and the place should be located away from any heat source. 5. Be careful when moving the unit due to its heavy weight

10 3.2.1 Environmental setting The unit can be operated properly under the following environmental conditions. No direct sunlight Ambient temperature: 64 O C to 86 O C Relative humidity not to exceed 85% Altitude not to exceed 2000m (6,562 feet) Keep refrigerator away from high frequency noise produced b y e q u i p m e n t a n d / o r m a c h i n e r y. Connect to grounded terminals only

11 3.3 Locking/Unlocking Casters & Leveling the unit The caster assembly allows for easy movement, locking and leveling of the unit. Use the following instructions to ensure the unit is level. Tool required Step 1: Place the unit in its location. Step 2: Lower the foot of each caster by turning the red height adjustment counterclockwise until it hits the floor. Turn the height adjustment a quarter turn or more to ensure the unit s weight is taken off the caster. This will lock the unit in place. Step 3: Place a level on the top of the door and check for level side-to-side and front-to-back. Step 4: Turn the height adjustment to raise or lower the unit until one is level

12 3.4 Power connection Main power should be connected to the unit according to the following procedure. STEP 1: Check the socket located at the upper part of the back side. STEP 2: Power cord should be connected to the socket at the back side

13 STEP 3: Press on the main switch upward after power cord is connected to the socket.. <Main switch> ON OFF Ensure the unit is connected to a power supply that is an appropriate voltage, phase capacity. Failure to connect to a proper connection of power will cause the risk of fire, electric shock and personal injury Never use a forked socket, or a double-tapped socket. Failure to obey a safety warning will cause a drop in a line voltage, resulting in a loss of power and causing risk of fire. Only Use the power cord supplied with the unit. 3.5 Pre start-up checks Make sure all electrical connections are tight. Make sure caster feet are lowered and have locked the unit in place. Make sure the unit is level side to side and front to back. Make sure there are no flammable or explosive liquids inside of chamber

23 6.0 Malfunction and troubleshooting 6.1 Power Symptoms Causes Solutions Wrong electric standard Check the ID plate on the side whether it is fit to the socket power, supply proper voltage and frequency for the power. The equipment is not on Circuit breaker is off or power failure The plug is not inserted completedly Check if the power is off. If the circuit breaker is off, fix it and operate the equipment again. Put plug into the socket again. Fuse short circuits frequently Socket/plug/power lines are damaged Fuses are disconnected. Too many plugs are connected Check the socket/plug/power lines and replace with new one if they are damaged. When the fuse is short circuitted, replace new one. 1. Check the voltage capacity supplied to the circuit breaker. 2. Check how many units are plugged into the socket. Use separate socket not exceeded voltage capacity. Display does not show when power is on Power cut The plug is not inserted completedly into outlet Check if power is out Put plug into the socket again

24 VFD display is showing with broken screen VFD segment error Request service Symptoms Causes Solutions Dial button does not work properly Dial buttom does not work at all Button malfunction Controller malfunction Button damage Request service Request service Request service 6.2 Temperature (refrigeration) Symptoms Causes Solutions Too many samples Make sure there is enough room for air to flow freely around the samples.
