Service and Cleaning
Draining the Tank
Always empty the tank before shipping.
1. Prepare a minimum 5 gallon (17.5 litre) heat resistant container to drain the tank water into.
2. Unplug the machine.
3. Remove the drain tray and front access panel.
4. Locate the silicone drain hose. Put the end of the drain hose into the bucket. Secure the end of the drain hose (i.e.
with tape) into the bucket.
5. Remove the hose clamp and plug.
6. Allow the tank to drain completely.
WARNING: Do not attempt to stop the flow of water once it begins to drain.
7. Once the tank is empty, securely replace the plug and clamp on the end of the hose. Reposition the drain
hose inside the hose clip on the left side wall.
8. Reassemble the front access panel and drain tray.
Purging Machine of all Water for Shipment in Cold Areas
The unit can be purged of water as follows:
1. Turn the power switch to the "OFF" position.
2. Drain the water tank (refer to instructions above.) Do not replace the drain hose plug and clamp until
further instructed.
3. Turn the power switch to the "ON" position. The display should indicate “lack of water” within 12 seconds. The 12
second delay signals that the heating element has been disabled due to the lack of water in the tank after it is
drained.
Important: If the display does not indicate “lack of water” within 12 seconds, turn the power OFF to
avoid burning out the heating element.
4. Listen for the inlet valve to energize. Ensure the tank drain tube is directed towards a container to catch residual
water before air is supplied to purge the line. To purge the inlet valve and water inlet tube, apply 10-20 psi com-
pressed air to the inlet valve connection for 10 to 20 seconds while the inlet valve is energized.
Note:
Do not energize the inlet valve for more than 5 minutes at a time. Otherwise, the watchdog timer will disable
the inlet valve. If this occurs, reset the machine by flipping the power switch off then on.
5. Reassemble the machine.
WARNING:
Draining of tank should be performed by a qualified service technician.
The tank contains 4 gallons (15.1 litre) of very hot water. May cause severe burns.
WARNING:
This procedure should be performed by a qualified service technician.
