• Do not damage the refrigerant circuit.

Review safety instructions before installing, using, or maintaining the equipment.

♦Before moving unit, ensure door is closed and casters (if installed) are unlocked and free of debris.

♦Before moving unit, disconnect the AC power cord and secure the cord.

♦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 products are stored at recommended temperatures determined by standards, literature, or good

laboratory practices.

♦ Using the equipment in a manner not specied by the manufacturer may impair the protection provided by the equipment.

♦Ensure product is stored safely, in accordance with all applicable organizational, regulatory, and legal requirements.

♦ The freezer is not considered to be a storage cabinet for ammable or hazardous materials.

♦ Use caution when moving a stacked conguration.

REQUIRED: Decontaminate parts prior to sending for service or repair. Contact Helmer or your distributor for

decontamination instructions and a Return Authorization Number.

1.6 General Recommendations

General Use

Allow freezer to come to room temperature before switching power on.

During initial startup, high temperature alarm may sound while the freezer reaches operating temperature.

Initial Loading

Allow chamber temperature to stabilize at the setpoint before storing product.

Product Loading Guidelines

When loading your freezer, take care to observe the following guidelines:

♦Never load freezers beyond capacity.

♦Always store items within shelves or drawers.

♦ Temperature uniformity is maintained by air circulation, which could be impeded if unit is overlled, particularly at the top

or back. Ensure a minimum of 2" (50 mm) clearance is provided below the fan.

Note

Products stacked against back wall may obstruct air ow and a󰀨ect performance of unit.

♦ Has a grounded outlet meeting the electrical requirements listed on the product specication label.

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

♦Upright units require a minimum of 8” (203 mm) above, and a minimum of 3” (76 mm) behind the unit for proper ventilation,

clearance, and feature access.

♦Undercounter units require a minimum of 3” (76 mm) of space behind the unit for clearance and feature access.

♦ Meets specied limits for ambient temperature and relative humidity as stated in the Product Specications section of

this manual.

2.2 Placement and Leveling

NOTICE

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

• To avoid damaging refrigerant tubing or risking refrigerant leak, use caution when moving or operating the unit.

• Use of leveling feet or casters is required.

Undercounter units only

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

• Do not lean on or push down on an open door or extended drawers.

1. Ensure door is secured and casters (if installed) are unlocked.

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

3. 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

NOTICE

• 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 at the same time.

• Do not lean on or push down on an open door or extended drawers.

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

and/or oor.

2.5 Temperature Probes

A probe bottle and container of propylene glycol have been provided with this unit. The propylene glycol is mixed with water

to create a solution which, when placed in the probe bottle, simulates the product stored in the freezer. The product simulation

solution temperature reects the product’s temperature during normal operation.

Notes

• Temperature probes are fragile; handle with care.

• Failure to ll probe bottle(s) or keep probe bottle(s) lled to the appropriate level may cause the chamber

temperature to display higher or lower than the actual temperature.

Primary Monitor Probe

The primary monitor probe bottle is located at the top left side of the freezer.

Upright probe bottle Undercounter probe bottle

Secondary Monitor Probe (upright i.Series models only)

The location of the secondary monitor probe varies based on the unit storage conguration.

Fill Temperature Probe Bottle

Notes

• Use approximately 4 oz. (120 mL) of product simulation solution (1:1 ratio of water to propylene glycol).

• Propylene glycol included in freezer box.

1. Remove probe(s) from bottle and remove bottle from bracket.

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

3. Secure cap on bottle and place in bracket.

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

Notes

• Upright access port is located on the top of the unit.

• Undercounter access port is located on the back of the unit.

Install Additional Probe Through Access Port

1. Peel back putty to expose the port.

2. Insert the probe through the port into the chamber.

3. Insert the probe into the bottle.

4. Replace putty, ensuring a tight seal.

2.6 Chart Recorder (if included)

Note

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

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

proper charge.

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. If full battery 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 the chart recorder by pressing and releasing the door (i.Series models) or pulling door open (Horizon Series and

undercounter models).

Install battery

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

Install / Replace Chart Paper

Note

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

is fully tightened.

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 from chart paper.

3. Place new 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.

Power Supply

The temperature chart recorder uses AC power when the system is operating. If AC power fails, the recorder continues to record

temperature with back-up power provided by the nine volt battery.

♦The LED indicator glows green continually when main power is functioning and the battery is charged.

♦The LED indicator glows red continually when main power is functioning and the batteries is either not installed or needs to be

replaced.

♦ The LED indicator ashes red to indicated the recorder is receiving power only from the back-up battery.
