INSTALLATION

The Low Temperature Incubator should be installed on a

level, stable floor. Install the 4 adjustable feet per

instructions inside package. Use the adjustable feet to level

the incubator. Locate the unit so that area in front of door

and kick grill is clear. To prevent heat build up within the

unit, do not install it where it will be exposed to strong

sunlight, nor near radiators, furnaces, or other sources of

heat. Do not install the incubator where flammable or

corrosive atmospheres may exist. The Low Temperature

Incubator is not to be used out-of-doors or where excessive

moisture or contamination could cause degrading of

mechanical or electrical components.

1. Remove all protective tape from doors and shelves.

2. Clean interior and exterior with warm soap and water.

Shipping tape residue can be removed using isopropyl

alcohol.

3. Uncoil line cord from rear of unit. Connect the plug to a

power outlet that complies with the electrical requirements

specified on the unit's label and with proper safety ground

connection. If line cord replacement is necessary, use CSA

types: SJ, SJO or SJT, 16 GA, 3 conductor or equivalent.

Door Reversal:

1. Disconnect unit from power source. On inside of door,

directly behind controller, open snapped conduit and

remove controller cable.

2. Remove screw that secures cable clamp holding

controller cable, then replace screw.

3. Remove controller cable from J clamps that run along

inside chamber side and back walls.

4. Place 3 J clamps (Provided) at approximately the same

spacing (on opposite side) as existing J clamps.

5. Support door with one hand remove screw securing door

to upper hinge, then lift door off bottom hinge.

6. Remove the three screws securing each hinge to

chassis.

7. Remove three plug screws covering holes on left side,

then install them in holes on right side,

8. Install hinges on left side using screws removed in step

6. Position hinge with door screw on bottom.

9. Position door on hinge then insert screw previously

removed in step 5.

10. Attach supplied latching duct to inside on door, in line

with controller cable toward opposite side on door from

other duct.

11. Route cable using J clamps and latching duct.

12. Remove screw on left front of enclosure and install

cable clamp with removed screw.

13. Adjust size of loop in cable where door is hinged to

ensure door can fully open and close without interference.

Displays chamber and set point temperatures in °C and

prompts from menu.

INDICATORS: (Front panel)

DELAY: Lights when delay start timer for compressor is

timing. Will begin timing when power is first applied or

when cooling is first turned off.

ALARM: Indicates that chamber temperature is not within

limits and the safety relay is opened.

COOL: Lights when cooling compressor is on.

HEAT: Lights when controller demands heat.

GENERAL FUNCTIONAL CHECKS

1.Turn power on to unit by placing the Power ON/ OFF

Switch to I (ON) position. The Controller (mounted on front

of door) will display S , then, 88.8 (to test display), then

begins reading actual chamber temperature.

Note: When power is first applied, if display indicates an L

instead of an S, a switch setting on the controller must be

changed. Refer to Replacing Temp Controller (TC1).

2. After 3 seconds, the alarm LED on the controller should

extinguish and the safety relay should close applying power

to the heater, fan, compressor relay and convenience

outlet.

indicate CAL. Release and press MENU again to display

Pct, press SET, display should indicate 100. Press and

release MENU again to indicate Pro, press SET, display

should indicate 00, press and release MENU to return to

normal control mode. Press SET to display control

setpoint, display should read 25.0. If the control setpoint or

any of the other parameters aren't set correctly, use the ∆

or ∇ keys while pressing SET to change the setting.

4. The DELAY LED will be lit for 7 minutes after power is

first applied, the COOL LED will be out during this delay

period. When the DELAY LED goes out, the COOL LED

will light and the compressor relay will close starting the

compressor.

5. Allow unit to stabilize for 1 hour at 25°C, to ensure that all

systems are functioning.

OPERATION

Perform the procedure under General Functional Checks if

incubator is new or hasn't been operated for a long time.

Controller operation:

Usually the only controller setting that is necessary to

change is the chamber temperature control setpoint. Other

parameters of the controller may be changed by accessing

them through the MENU key, covered later.

Changing Chamber Temperature Control Setpoint

1. The chamber temperature is continuously displayed,

unless a key is pressed.
