Hoshizaki AM-50BAE-DS B. Optional Drain Pump HS-0248 or HS-5061, Priming Instructions

B. Optional Drain Pump HS-0248 or HS-5061

If the optional drain pump (HS-0248 or HS-5061) is installed, test its operation at least once a year as outlined below. Note that the pump has power even when the control switch is in the "OFF" position.

NOTICE

If the optional drain pump is not operating properly or not primed properly (HS‑0248), it will adversely affect performance, component life, and warranty coverage and may result in costly water damage.

1)Move the control switch to the "OFF" position, then unplug the appliance from the electrical outlet. WARNING! To reduce the risk of electric shock, do not touch the control switch or plug with damp hands.

2)Remove all ice from the ice storage bin.

3)Plug the appliance back in.

4)Slowly pour 24 to 30 oz. (710 to 890 ml) of water over the ice storage bin drain hole in the ice storage bin.

5a) HS-0248: If water pumps out properly and the drain pump then de-energizes, proceed to step 6. If water does not pump out properly and/or the drain pump does not de‑energize, follow the steps below to prime the drain pump.

Priming Instructions

a. Disconnect the appliance's power cord from the electrical outlet, then reconnect to the electrical outlet. WARNING! To reduce the risk of electric shock, do not touch the power cord with damp hands.

b. Slowly pour another 24 to 30 oz. (710 to 890 ml) of water over the storage bin drain hole in the storage bin. If not already energized, the drain pump should energize.

c. Confirm that water is discharged through the discharge hose. The drain pump should then de‑energize. If not, repeat steps a through c until water is discharged through the discharge hose and the drain pump de‑energizes. The drain pump is primed when the drain pump de-energizes.

d. If water now pumps out properly and the drain pump de-energizes, proceed to step 6. If water still does not pump out properly and/or the drain pump does not de‑energize, replace as needed.

5b) HS-5061: If water pumps out properly and the drain pump then de-energizes, proceed to step 6. If water does not pump out, confirm 115VAC to drain pump, replace as needed. Priming does not apply to HS-5061.

6)Move the control switch to the "ICE" position.

7)Pour another 24 to 30 oz. (710 to 890 ml) of water into the ice storage bin, then completely restrict the discharge hose while the drain pump is operating. See Fig. 2. Pour more water into the ice storage bin until the appliance turns off. The drain pump will continue to operate. Check for leaks.
