1 About This Manual

This manual provides information on i.Series®and Horizon Series™upright laboratory, blood bank, and pharmacy refrigerators. It is

intended for use by end users of the refrigerator and authorized service technicians.

Models are indicated by a distinguishing model number that corresponds to the series, type, number of doors, and capacity of the

refrigerator. For example, “iLR125” refers to an i.Series Laboratory Refrigerator with 1 door and a capacity of 25 cu ft.

Generic references are used throughout this manual to group models that contain similar features. For example, “125 models”

refers to all models of that size (iB125, HB125, iLR125, HLR125, iPR125, HPR125). This manual covers all upright refrigerators,

which may be identied singly, by their size, or by their respective “Series”.

2 InstallationandConguration

2.1 Location Requirements

♦ Grounded outlet meeting the electrical requirements listed on the product specication label.

♦ Clear of direct sunlight, high temperature sources, and heating and air conditioning vents.

♦ Minimum 8“ (203 mm) above, and minimum 3” (76 mm) behind.

♦ Meets limits specied for ambient temperature (15˚C to 32˚C) and relative humidity.

2.2 Placement and Leveling

CAUTION

• The water evaporation tray, located on the rear of the refrigerator, may be hot. Do not use the tray as a handle.

• To prevent tipping, ensure the casters are unlocked, leveling feet (if installed) are lifted, and doors are closed before

moving the refrigerator.

1. Roll refrigerator into place and lock casters.

2. Ensure refrigerator is level.

Notes

• Helmer recommends the use of leveling feet.

• Use a wrench to raise or lower leveling feet. When the refrigerator is level, the bottom of the unit cooler will slope

downward from front to back and be parallel to the oor.

2.3 Connect Back-Up Power

The monitoring system and chart recorder each have a back-up battery system, enabling a period of continuous operation if power

is lost.

Battery life varies by manufacturer as well as voltage level remaining. Providing full power is available and no battery-related

alarms are active, back-up power for the monitoring system is available for up to 20 hours (the Low Battery alarm will activate after

approximately 18 hours of battery use). Providing full power is available, back-up power for the optional Access Control system is

available for up to 2.5 hours.

CAUTION

Before installing or replacing batteries, switch AC power and back-up battery OFF. Disconnect refrigerator from AC power.

Notes

• The optional Access Control system uses the monitoring system back-up battery for back-up power in the event of

power failure.

• The monitoring system will start on back-up battery power alone. If the refrigerator was not previously connected to AC

power and the back-up battery is switched on, the monitoring system will begin running on back-up battery power.

• If AC power is lost, the monitoring system will automatically disable some features to prolong back-up battery power.

Data collection will continue until back-up battery power is depleted.

The back-up battery is located on top of the refrigerator. For 111 models, a removable panel provides access to the back-up battery.

Monitoring system back-up battery (supplies power to optional Access Control system).

360373/B 8

2.4 Prepare for Monitoring

The back-up battery switch is switched off for shipping. Switch the back-up battery switch ON to provide the monitoring system

and optional Access Control system with back-up power in the event of AC power failure.

Temperature Probes

Notes

• Temperature probes are fragile; handle with care.

• The number and location of probes varies by model.

• Remote probes may also be introduced through the existing top port ,or through a side access port if available, and

immersed in existing probe bottles.

The number and location of probes varies by model. External probes may be introduced through the existing top port and

immersed in existing probe bottles, or through a side access port which is available in some models.

Probe bottle(s) along with a container of glycerin have been provided with this unit. The glycerin is used to create a solution which

simulates the product stored in the refrigerator. The product simulation solution temperature reects the product’s temperature

during normal operation.

Each probe bottle should contain 4 oz. (120 mL) of product simulation solution at a 10:1 ratio of water to glycerin.

Left: Probe bottle with temperature and chart recorder probes.

Middle: Top access port. Right: Side access port.

Fill Probe Bottle

1. Remove all probes from bottle and remove bottle from bracket.

2. Remove cap and ll with 4 oz. (120 mL) of product simulation solution.

3. Install cap and place bottle in bracket.

4. Replace probes, immersing at least 2” (50 mm) in solution.

Install Additional Probe Through Top Port

1. Peel back putty to expose port.

2. Insert probe through port into chamber.

3. Insert probe into bottle.

4. Replace putty, ensuring a tight seal.

Install Additional Probe Through Side Port

1. Remove interior and exterior plugs to expose side access port.

2. Insert probe through port into chamber.

3. Insert probe into bottle.

4. Ensure port is tightly sealed using putty.

Chart Recorder (if included)

Notes

• If chart recorder has been operating on battery power, the battery should be replaced to ensure the back-up source has

proper charge.

• For complete information, refer to the Temperature Chart Recorder Operation and Service Manual included with the unit.

The chart recorder has a back-up battery system, enabling a period of continuous operation if power is lost. Battery life varies

by manufacturer as well as voltage level remaining. Providing full power is available, back-up power for the temperature chart

recorder is available for up to 14 hours.

Prior to use:

Place probe in bottle with primary monitor probe.

Set up and Operation

Access chart recorder by pressing and releasing the door to open.

i.Series chart door

Install Battery

Connect the leads to the battery to provide back-up power to the chart recorder.

Install / Replace Chart Paper

Notes

• For accurate temperature reading, ensure the current time is aligned with the time line groove when chart knob is tightened.

• Contact Helmer Customer Service to reorder chart paper; part number 220366 (52 sheets)

Chart recorder stylus and time line groove

1. Press and hold C button. When stylus begins to move left, release button. The LED ashes.

2. When stylus stops moving, remove chart knob then move knob up and away.

3. Place chart paper on chart recorder.

4. Gently lift stylus and rotate paper so current time line corresponds to time line groove.

5. Hold chart paper in place while making sure the chart knob is fully tightened. (Failure to fully tighten the knob can result in paper

slipping and losing time.)

6. Press and hold C button. When stylus begins to move right, release button.

7. Conrm stylus is marking on paper and stops at the correct temperature.

8. Calibrate chart recorder to match primary temperature if needed and close recorder door.
