3. PRE-OPERATION PROCEDURES
Installation Precautions
Install equipment on a level surface.
Install unit on level and even surface. Failure to do so may cause abnormal vibrations or
noise, possibly resulting in complications and/or malfunction.
Stabilize equipment properly to assure safe operation and a safe work area
Implement appropriate safety measures suitable for the installation environment.
In the event of an earthquake or other unforeseen incident, unit may unexpectedly shift or
fall, causing serious injury.
Always connect power cable to appropriate facility outlet or terminal.
Connect power cable to a suitable facility outlet or terminal, according to the electrical
requirements.
Electrical
requirements:
WG251: 115 V AC single phase 50/60 Hz 11 A (ELB capacity: 20 A)
WG1001: 220 V AC single phase 50/60 Hz 18 A (ELB capacity: 30 A)
Standard test conditions with no load should be as follows. Operational voltage range:
±
10 %, Voltage range at which specified performance is guaranteed:
±
5 %, Frequency
rating:
±
1 %.
* Check the line voltage on distribution board and properly evaluate whether to utilize a line
being shared by other equipment. If unit is not activated by turning on ELB, take an
appropriate course of action, such as connecting unit to a dedicated power source.
Inserting multiple cords into a single outlet, using branch outlets or extension cords, may
cause a drop in voltage, which may affect performance, resulting in failure to control or
maintain proper temperature.
Ensure adequate raw water pressure as specified.
●
Operate with tap water pressure in the range of 0.5 to 5.0 × 100 kPa(0.5
~
5 kgf/cm2),
including nighttime.
●
The ranges of the raw water pressure is the same when using optional "water supply unit"
(P.66).
Raw water
●
Use tap water as raw water.
●
Do not use chemicals or lubricants. Equipment malfunction may result.
●
Check that the raw water is not contaminated with red rust. If raw water is not clean, it may
cause equipment malfunction. Likewise, water quality may fall below specified quality level.
