Before Use

Installation and Preparation Before Use

WARNING

Do NOT Use Where Flammable or Explosive Gases or Vapors Are Present.

Do NOT operate this product where there are flammable or explosive gases or vapors since this product is an arcing device--it produces an arc at power-on--and not explosion-proof. Operation of the product in such an environment may cause a fire or explosion.

Use Protective Grounding.

Always connect the protective grounding to the ground, to prevent electrical shock or fire due to stray current. Do NOT connect the grounding wire to gas supply piping. This may cause a fire.

Do NOT connect the grounding wire to the grounding for telephone lines or lightning rods. This may cause a fire or electrical shock.

A grounded 3-prong power outlet is recommended.

Grounded power

Power cord

If there is no grounding terminal

If a grounding terminal is not provided by the electric facility, a grounding pole (grounding resistance ≤ 100 Ω , Japanese Industrial Standard Class 3) must be provided. Since this requires personnel qualified to do electrical work, consult the dealer from whom you purchased this product or the nearest Yamato Scientific sales representative office.

Before Use

Installation and Preparation Before Use

WARNING

Observe the Power Rating.

Use a power outlet whose rating meets the electric capacity.

Electric capacity: 100 V AC, 9 A for all IK/IM series products

Do not use a multiple-outlet adapter. It may cause overheating.

Avoid Uneven Surfaces.

Install the product on a level surface. Installing on an uneven surface may cause unanticipated accidents or failures.

Installation Location

Avoid the following locations:

Outdoors

 

Where flammable, corrosive, or

 

 

hazardous gases are present

 

Where the ambient temperature is

 

 

35°C or higher or 5°C or lower

 

Where rapid changes in temperature

 

 

occur

 

Humid or dusty place

 

In direct sunlight

 

Where flooring is not strong enough to

 

 

support this product, or on a rack or

 

 

the like

 

Where there is vibration

Front

Nearby equipment which should be

 

kept away from vibrations

 

A clearance of at least 30 cm is needed on both sides and at the rear (see the figure on the right)

Before Use

Installation and Preparation Before Use

WARNING

Make fine adjustments for precise level installation.

After determining where to install the product, use the four adjusters to support this product securely.

At that point, also use a level or the like to insure that the product is precisely level. A forward

inclination is especially dangerous since the front door may come open and the shelf inside may slide out from the vibration. After adjusting the adjusters, tighten all the adjusters in place with the lock nuts.

Do not allow the weight of the product to rest on any caster.

After Installation

To avoid injury, take adequate measures to insure that this product will not fall in the event of an earthquake or from mechanical shock.

Drainage of Water

z Water that has condensed inside the incubator is drained through the hose in the rear. Include an adequate-size drain pan

zThe hose is as shown in Figure 1 when it is delivered to you; however, the layout can be changed as shown in Figure 2 if it is more suitable for your location.

To change the hose layout

1.First make sure that the power cord is unplugged. Detach the rear cover and louver. To detach the louver, refer to page 23, “Daily Maintenance and Inspection.”

2.Let the end of the hose stick out from the bottom hole as shown in Figure 2.

3.If the hose seems to be too long, you can make it shorter by cutting it with scissors or the like

4.When laying the hose, be careful not to allow it to be in contact with the V pulley or cooling fan.

5.Be careful not to allow the hose to become twisted.

6.To diminish the intrusion of outside air, make a loop in the hose to make a trap.

7.After the change, reattach the rear cover and louver in their original positions.
