Cartridge Change-Out Procedure - 3M DIDF260-CL Installation And Operation Instruction Manual

Cartridge Change-out Procedure

To reduce the risk associated with property damage due to water leakage:
• The disposable filter cartridge MUST be replaced every 12 months or sooner at the rated capacity or if a noticeable reduction in flow rate occurs.
The ice cartridge (Model HF60-S-SR5) has a yellow label and will only fit into the head on the left side of the manifold (head has a yellow 3M label).
The beverage cartridges (Model HF60-CL) will only fit into the heads on the right side of the manifold (heads have a blue 3M label).
DIDF260-CL System Shut-Off procedure:
Cartridges will need to be changed at least every 12 months or when low pressure is indicated on the manifold's pressure gauge, whichever
occurs first. Depending on local water quality, you may need to change the cartridges prior to the recommended change-out. The loss of flow to
carbonators or improper fill at the ice maker are also indicators that the cartridges will need to be replaced.
1. Shut-off ice and beverage inlet water (2 total) and depressurize system per instructions below.
2. Replace HF60-S-SR5 (yellow label), and HF60-CL (blue label) cartridges in the sequence shown below. Then complete DIDF260-CL System
Pre-Start-Up procedure as shown below before starting system back up.
HF60-S-SR5 Cartridge (yellow label) Replacement:
1. Relieve pressure in the ice line by opening valve downstream.
2. Push and hold yellow tab to release cartridge locking mechanism while simultaneously rotating cartridge to the left.
3. Using both hands and holding the cartridge from the bottom, rotate the cartridge a quarter turn to the left and gently pull down. NOTE: A
small amount of water will drain from manifold as cartridge is removed.
4. Remove sanitary cap from new cartridge. Apply a light coat of water or food-grade silicone lubricant to the o-rings. Install with a quarter
turn to the right until cartridge comes to a complete stop. NOTE: Cartridges are keyed to fit in proper location only.
HF60-CL Cartridge (blue label) Replacement:
1. Relieve pressure to beverage/coffee line by opening and closing the venting valve in between the HF60-CL cartridges.
2. Push and hold yellow tab to release cartridge locking mechanism while simultaneously rotating cartridge to the left.
3. Using both hands and holding the cartridge from the bottom, rotate the cartridge a quarter turn to the left and gently pull down. NOTE: A
small amount of water will drain from manifold as cartridge is removed.
4. Remove sanitary cap from new cartridge. Apply a light coat of water or food-grade silicone lubricant to the o-rings. Install with a quarter
turn to the right until cartridge come to a complete stop. NOTE: Cartridges are keyed to fit in proper location only.
