1 About this Manual

This manual provides information on how to use i.Series®and Horizon Series™undercounter laboratory and plasma storage

freezers. It is intended for use by end users of the freezer 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

freezer. For example, “iLF105” refers to an i.Series Laboratory Freezer with 1 door and a capacity of 5 cu ft, while “HLF104” refers

to a Horizon Series Laboratory Freezer with 1 door and a capacity of 4 cu ft.

Generic references are used throughout this manual to group models that contain similar features. For example, “105 models”

refers to all models of that size (iPF104, iPF105, HPF104, HPF105, iLF104, iLF105, HLF104, HLF105). This manual covers all

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

♦Never physically restrict any moving component.

♦Avoid removing electrical service panels and access panels unless so instructed.

♦Keep hands away from pinch points when closing the door.

♦Avoid sharp edges when working inside the electrical compartment and refrigeration compartment.

♦Ensure biological materials are stored at recommended temperatures determined by standards, literature, or good

laboratory practices.

♦ Proceed with caution when adding and removing samples from the freezer.

♦Do not open multiple, loaded drawers or baskets at the same time.

♦Use manufacturer supplied power cord only.

♦ Using the equipment in a manner not specied by Helmer Scientic may impair the protection provided by the

equipment.

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 3”(76 mm) of space behind unit.

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

2.2 Placement and Leveling

CAUTION

• To prevent tipping, ensure the casters (if installed) are unlocked and the door is closed before moving the freezer.

• Do not sit, lean, push or place heavy objects on top surface.

1. Move freezer into place. Lock casters if installed.

2. Ensure freezer is level.

Note

Helmer recommends the use of leveling feet and wall and oor brackets (PN 400472-2) for stabilization. Contact Helmer

Technical Service for parts and instruction.

2.3 Stacked Undercounter Units

CAUTION

• For stacked conguration, both units must have leveling feet installed.

• Back brace bars and front stabilizing brackets must be installed (Blue - PN 400821-1; Stainless Steel - PN 400821-2)

• When stacking units, place the heavier unit on the bottom.

• Do not open multiple loaded drawers or baskets at the same time.

Contact Helmer or your distributor for more information regarding the stacking kit and methods to secure both units to the wall

and/or oor.

2.4 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, 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 switch OFF. Disconnect freezer 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 freezer was not previously connected to AC

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

The back-up battery is located below the chamber, behind the front panel. The panel cover must be removed to access the battery.

Monitoring system back-up battery.

2.5 Prepare for Monitoring

The back-up battery is switched OFF for shipping. Switch back-up battery 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.

• Remote probes may also be introduced through the existing port and immersed in existing probe bottles.

The probe bottle along with a container of propylene glycol have been provided with this unit. The propylene glycol is mixed with

water to create a solution which simulates the product stored in the freezer. The product simulation solution temperature reects

the product’s temperature during normal operation.

The probe bottle should contain 4 oz. (120 mL) of product simulation solution at a 1:1 ratio of water to propylene glycol.

Left: Probe bottle with temperature probe Right: Rear 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 Rear 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.

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:

Route the chart recorder probe through the rear access port and place in bottle with primary monitor probe.

Set Up and Operation

Access chart recorder by pulling the door open.

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 to indicate current

temperature range.

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 and reinstall 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.

External Monitoring Devices

The remote alarm interface is a relay switch with three terminals:

♦ Common (COM)

♦ Normally Open (NO)

♦ Normally Closed (NC)

Terminals are dry contacts and do not supply voltage. Interface circuit is either normally open or normally closed, depending on

terminals used.

Requirements for your alarm system determine which alarm wires must connect to terminals.

CAUTION

• The interface on the remote alarm monitoring system is intended for connection to the end user’s central alarm

system(s) that uses normally-open or normally-closed dry contacts.

• If an external power supply exceeding 33 V (RMS) or 70 V (DC) is connected to the remote alarm monitoring system’s

circuit, the remote alarm will not function properly and may cause damage to the control board or result in injury to the user.

The terminal on the remote alarm interface have the following maximum load capacity:

♦ 0.5 A at 125 V (AC)

♦ 1 A at 250 V (DC)

Connect to Remote Alarm Interface

1. On back of freezer, locate the remote alarm terminals.

2. Connect remote alarm wires to appropriate terminals, according to requirements for your alarm system.

3. Use a cable tie to relieve strain on alarm wires (as necessary).
