How to fix if the mix in the hopper of Carrier C708 Freezer is too cold?
If the mix in the hopper of your Carrier Freezer is too cold: * The temperature is out of adjustment. Adjust hopper temperature. * The agitator paddle is not installed. Install the agitator paddle.
What causes low head pressure in a Carrier C708 Freezer?
Low head pressure in a Carrier Freezer is caused by a refrigerant shortage. Repair the leak and recharge the system.
Why does my Carrier C708 shut off and produce a fault tone?
If your Carrier Freezer shuts off and produces a fault tone, it could be due to: * A fault alert. Check the fault screen in the operator’s menu. * Insufficient air space. Allow 6” (152 mm) minimum clearance around both sides of unit and place the back against a wall.
Why is there excessive mix leakage in my Carrier C708 Freezer?
Excessive mix leakage through the rear of your Carrier Freezer into the drip pan can occur because of: * A worn or missing drive shaft seal. If worn, nicked or missing, replace the drive shaft seal. * Inadequate lubrication. Lubricate properly. * The drive shaft rotates forward. Check gear alignment.
What to do if the mix in the hopper of Carrier C708 is too warm?
If the mix in the hopper of your Carrier Freezer is too warm: * The temperature is out of adjustment. Adjust hopper temperature. * The agitator is not installed. Install the agitator.
Why is the liquid line of my Carrier C708 Freezer hot?
If the liquid line in your Carrier Freezer is hot, it is likely due to a shortage of refrigerant. Repair the leak and recharge the system.
Why does my Carrier Freezer operate for a long time?
If your Carrier Freezer operates for extended periods, it could be due to: * Worn scraper blades. Replace the scraper blades. * High overrun product (C708/C716). Check pump operation for correct air/mix ratio.
Why is no product dispensed from my Carrier C708 Freezer when the draw valve is open and the machine is in “AUTO” mode?
If no product is dispensed from your Carrier Freezer when the draw valve is open and the machine is in “AUTO” mode, consider these possibilities: * The door spout is plugged. Break down the machine and dislodge the door spout clog. * The beater is rotating counterclockwise. Correct beater rotation to clockwise. * There is inadequate mix in the hopper (mix out light is lit). Fill hopper with mix.
What causes the product from Carrier C708 Freezer to be too stiff?
If the product from your Carrier Freezer is too stiff, it may be because: * The product viscosity is set too cold. Adjust the product viscosity. * The air/mix pump is incorrectly assembled or malfunctioning (C708/C716). Re-assemble pump or replace faulty components.
Why is product not being fed into the freezing cylinder of my Carrier C708 Freezer?
If product isn't being fed into the freezing cylinder of your Carrier Freezer, it could be due to: * Inadequate mix in the hopper (mix out light is lit). Fill hopper with mix. * Air/mix pump incorrectly assembled (C708/C716). Assemble pump according to instructions in the Operator’s Manual. * Incorrect usage of the mix feed tube (C709/C717). Follow the correct feed tube procedures and use of the air orifice.
