Start-Up Checklist
Warning: Only service personnel experienced and certified in refrigeration and qualified to work
with high-voltage electrical equipment should be allowed to install or work on this Tube-Ice® machine.
Make sure all of the following items have been checked before starting the machine for the first time:

Check that the water inlet connections are attached properly. The water inlet shutoff valves for the
condenser and the water tank should be open. The water level in the water tank should be at a height
where the makeup water float valve will be closed when the machine is idle.

Make sure the cutter motor gear reducer is lubricated.

Check that the compressor crankcase oil level is at the proper height as indicated by the compressor
body sight glass.
 Open all necessary valves, including:
o
Compressor service valves
o
Thawing gas-line stop valve
o
King valve
o
Both float switch stop valves

Except the charging valves, check that all stop valves in the refrigerant system are open, according to the
attached tags. All valves are tagged with instructions.
 Immediately after opening the refrigerant valves, check the entire machine for refrigerant leaks with an
electronic leak detector or by doing a bubble test.

Check that all water supply lines are open to the water tank and all water tank drain valves are closed.

Set the Ice/Off/Clean switch to the Ice position.

Close the exterior disconnect switch to energize the crankcase heater, and check supply voltage against
that on motor nameplate for compliance before switching on disconnect.
Start-Up Procedure (Initial Start-Up)
Note: The machine will start in harvest mode when set to Ice . If the pump is already primed, skip to Step 4.
To perform the start-up of the machine, follow the steps below:
1. Set the Clean/Off/Ice selector switch to the Clean position.
2. Push Start (PB2) to start the water pump.
3. The pump can be stopped and started by pushing Stop and Start . The water should be circulated for a
minimum of 5 minutes to prime the pump, purge the tubing of air, and lubricate the cutter bearing.
4. When there is good water flow, turn the Clean/Off/Ice selector switch to Ice . The machine will then
start in a harvest (thaw) period with the compressor running.
5. At the termination of the harvest (thaw) period, the machine will begin the freeze period.
6. Be sure to observe a minimum of 4 cycles of ice production to confirm the satisfactory operation of the
machine (approximate time for 4 cycles is 60
– 80 minutes).
7. Complete the remaining part of the Warranty Registration/Start-Up Report upon initial machine start-
up and return it to Vogt Ice, LLC.
