1 About this Manual
This manual provides information on i.Series®and Horizon Series™ pass-thru 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, “iB225” refers to an i.Series Blood Bank refrigerator with two doors total (one door on the clean room
side of the unit, and one door on the control side of the unit) and an approximate capacity of 25 cu ft.
Generic references are used throughout this manual to group models that contain similar features. For example, “225 models”
refers to all models of that size (iB225, HB225, iPR225, HPR225). This manual covers all pass-thru refrigerators, which may be
identied singly, by their size, or by their respective “Series.”

2.2 Placement and Leveling
CAUTION
• To prevent tipping, ensure the casters are unlocked and doors are closed before moving the refrigerator.
♦Roll refrigerator into place and lock casters.
♦ Ensure refrigerator is level.
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 i.Lock™ interlock feature is
available for up to 2 hours.
CAUTION
Before installing or replacing batteries, switch AC power and back-up battery OFF. Disconnect refrigerator from AC power.
Notes
• The optional i.Lock™ interlock feature (available only in Pharmacy models) 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.

2.4 Prepare for Monitoring
The back-up battery switch is switched o for shipping. Switch the back-up battery switch ON to provide the monitoring system
and optional i.Lock interlock 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 ports, and immersed in existing probe bottles.
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 reects 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.
Right: Top 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.
