1 ICE & WATER INTRODUCTION
Ice making and water dispensing facilities are being introduced to the E522B Active Smart refrigerators.
The introduction required design changes to some components and to the physical movement and/or position of other components. The functionality of the Active Smart product including downloading and diagnostics have not changed.
Listed below are the changes to the E522B Active Smart with the introduction of Ice and Water.
1. Through-the-door water dispensing
This feature incorporates:
The Pressure Dispensing Pad
The pressure dispensing pad (located underneath the electronic display on the door activates water dispensing when pressed
Water Piped to Door Through Door Hinge
Water is delivered to the door via water hose piped through the door hinge.
Water Tank
The water tank is located in the top back rear of the PC compartment and feeds the water dispenser on the door via the water hose, through the door hinge.
2. External water inlet plumbing
Delivers water for ice making and water dispensing through a 12-volt water valve.
3. External Water Filter
An external in-line water filter is to be fitted to each Ice and Water refrigerator, which will come standard with every Ice & Water product.
4. Automatic Ice Maker
The internal automatic icemaker is located on the ceiling of the FC compartment, on the left hand side. The icemaker can be disassembled and removed for servicing.
5. New PC Temperature Sensor Position
Due to the location of the water tank in the back of the PC compartment, the PC temperature sensor position is now located in the centre LHS of the PC duct cover.
6. New Display /Temperature Control location
The temperature control/ Digital Display panel is located on the front of the PC door
7. Electronics Power Control Board
The electronics have been updated to run the ice and water systems with the addition of a small circuit board attached to the power controller. Although the electronics are still stage
4.2, they are NOT interchangeable with non-ice and water Active Smart products.
