Incubator
-
Under no circumstances should the unit be disassembled, repaired, or converted by unqualified people. Failure
to follow these instructions may cause personal injury and/or loss of property due to malfunctions, electric
shocks or fire.
Should the unit malfunction, turn off the incubator and disconnect the power supply. Continuing to operate
the unit when it shows signs of malfunctioning may cause electric shocks or fire.
The following troubleshooting guidelines address some of the basic problems that can be solved by the user or
operator. However if the problem persist, please contact your local distributor.
Problem 1: Unit will not turn on
Possible Cause Corrective Actions
Power failure
Is the cord set connected to the power inlet at rear of cabinet as defined in the
installation section of the manual?
Is there power at the electrical outlet which the unit is plugged into?
Use voltmeter or test pen to check power on the electrical socket.
Is the unit’s power switch turned on?
Check whether power cord has been connected properly into the wall/building
socket and also into the incubator.
Check whether the power cord is giving power, measure the AC voltage between
the live and the neutral terminal of the cord by using a voltmeter. If voltage is not
/-2% of the socket voltage, replace the power cord.
Check the fuse of the power cord.
Problem 2: CO
2
level is below or above CO
2
set-point
Possible Cause Corrective Actions
Unit is not connected to the
pressure regulated CO₂
source.
Check gas hose connection at the rear of unit to the CO
2
source as defined in the
installation section of the manual.
CO
2
inlet pressure not
regulated correctly.
The CO
2
inlet gas pressure should be regulated to approximate 15 psig.
CO
2
gas tank is empty.
Replace CO
2
gas tank.
In-line filter is dirty /
saturated. Replace in-line filter.
Gas hose is leaking.
If hose is leaking, check the pressure regulator to ensure CO
2
inlet pressure is not
more than 15 psig.
Check for leakage at hose connection.
Gas hose is dirty or
obstructed.
Check physically for dirt accumulation or obstruction, clean or replace it.
CO
2
set-point was recently
lowered or raised. Unit is still
not stabilized after the set-
point was changed.
Check CO₂ set-point. Allow 2 hours for the unit to stabilize after adjustment of new
set-point.
If the CO
2
set point is lowered, the outer and inner doors must be opened.
Inner door opened for an
extended period of time. Close the door and let the unit stabilize.
Access port stopper at the
rear of cabinet was removed
or not install.
Ensure access port stopper and filter are installed.
Air leakage through Inner
door gasket.
Check installation of the gasket ensure it is properly secure to the cabinet and that
there is no gap.
Check the joining ends of the gasket to make sure there is no gap. Use silicon
sealant to seal the joins if there is a gap.
Check gasket profile is not deformed or torn. Otherwise replace new door gasket.
