15

Connection of CO2 gas cylinder

WARNING

Check the gas type and ensure that it is fit for the purpose. Make sure that all pipes are

connected correctly and are not liable to become disconnected. Ensure that the gas pressure is

set at the specified value. Improper connection of the gas pipe or use of incorrect gas pressure

may result in leakage of CO2 gas. Elevated level of CO2 gas can be hazardous to health and may

lead to asphyxiation and risk of death.

Use a liquefied CO2 gas cylinder, not a siphon (dip tube) type. The CO2 gas should be 99.5 % or more

pure.

1. Use a gas regulator rated at 25 MPa(G) (250 kgf/cm2(G), 3600 psi(G)) on the primary side and 0.2

MPa(G) (2.0 kgf/cm2(G), 30 psi(G)) on the secondary side with flow rate of 77 L/min.

2. Using the gas supply pipe provided, connect the gas regulator to the connecting port for CO2 gas pipe

located at the rear upper side of the CO2 incubator.

3. Set the CO2 pressure on the secondary side to 0.1 MPa(G) (1.0 kgf/cm2(G), 14.5 psi(G)) (at gas

injection). Excessive pressure may cause disconnection of internal pipes inside the CO2 incubator which

will result in leakage of CO2 gas into the atmosphere. Elevated level of CO2 gas can be hazardous to

health and may lead to asphyxiation and risk of death. The repair of the incubator will be necessary

if the internal pipe is disconnected.

4. Check that no gas is leaking at any point where the pipe connects with the gas regulator or the CO2

incubator.

Note:

• Refer to “Procedure for replacement of gas cylinder” enclosed with the unit at the time of replacement.

• The incubator, including the gas supply pipes and services must be examined at frequent intervals to

ensure they are safe. Ensure that items such as pipes are replaced if there is any sign of deterioration.

16

CAUTIONS FOR USING EQUIPMENT IN CHAMBER

● Avoid abnormal temperature increase when an equipment is used in the chamber

When using a heat emitting equipment such as a shaker or a bottle roller, the chamber temperature may

rise abnormally. Abnormal rising of the chamber temperature is dangerous, so make sure to operate

equipment without abnormal temperature rising.

● If there is too much heat emission from the equipment in the chamber

The chamber temperature may deviate very much from the setting temperature when a heat generator

(heater, motor, etc.) of the equipment is energized in the chamber.

● When operating an equipment in the chamber, use at "No humidifying mode" (refer to page 21).

High humidity may cause a failure, a current leakage or a fire to an equipment in the chamber.

● When operating an equipment in the chamber, make sure there is no water in the water

reservoir.

17

PREVENT CONTAMINATION

To prevent contamination of the chamber, select an appropriate location for installation as well as the

complete disinfection of the chamber components.

● Avoid hot and humid location

Avoid location with high temperature and/or humidity as the presence of bacteria in the air is greater than

in normal environment.

● Avoid drafty location and location with many passers-by

Avoid locations near doors, air conditioners, fans, etc., where slight breezes can facilitate the entry of

bacteria into the chamber.

● Installation in a sterile room

To get the cultivation more efficiently, install the unit in a sterile room.

● Use clean containers

The contamination is mainly caused by the containers such as Petri dishes or bottles stored in the

chamber. Always keep the containers clean.

● Always keep the chamber clean

The condensation may be caused on the inside of the door by spilled water form water reservoir or

opening of outer door for long period. Wipe off the condensation completely with a sterile dry gauze.

Especially when the culture medium is spilled, clean and disinfect the chamber immediately. Refer to

page 27 “Routine maintenance” for details.

● Keep the inside panels dry

To protect the inside of the unit from contamination, the inside panels should always be kept dry. If

water is spilled from a water reservoir or if the door is kept open for a long period, condensation will form

on the panels, allowing germs to breed. In such a case, wipe away the water with a dry sterile gauze.

Particularly, if the medium is spilled, wipe it up immediately and sterilize the area.

● Fill the water reservoir with sterile distilled water

Always use sterile distilled water of approximately 20 L to fill the water reservoir. The water level alarm

lamp (RH PAN) on the control panel blinks when the amount of water is less than approximately 5 L.

Refill the sterile distilled water to the water reservoir when the water level alarm lamp (RH PAN) blinks.

Note that when low temperature water is poured, the chamber temperature drops significantly. Clean

the water reservoir once a month.

● Do not place the unit in the direct air flow from an air conditioning system

Cool air from an air conditioning system may cause condensation and lead to possible contamination.

18

CAUTIONS FOR CULTURE

● Do not subject to direct air flow

Do not allow the air for air conditioning to hit the unit or door directly. Direct hit may cause condensation

or contamination.

● Tray

Make sure to set the bottom tray to the bottom position of side duct with tray support. This may cause

condensation on bottom cover by varying air flow inside chamber.

● Do not block holes on the side duct with the culture vessels.

When storing cultures in the chamber, take care not to block holes on the side duct with the Petri dishes

or roller-bottle racks to allow adequate air circulation. Blockage of holes may result in uneven

temperature distribution and CO2 concentration in the chamber.

● Stored materials

Never place acid or alkaline materials or materials that release corrosive gas in the chamber. Such

materials can cause failure resulting from discoloration or corrosion.

● Open/close the doors gently

Ensure you close the doors gently. Robust closing may cause spillage of medium, incomplete closing,

or damage of gasket.

● Fix the tray supports and trays securely

Incomplete installation may cause injury or damage.

● Never lean or press on the glass.

Intentional force may cause injury if the glass breaks.

● Do not lean on the door

This may cause injury, current leakage, or electric shock if the unit tips over or door drops out.

● Alarm

Always investigate the cause and fix the alarm condition immediately when the alarm is activated. Refer

to page 24 for alarm details.
