PowerStar AE-115 is a 17.25 kW 2x240 Volt Point-of-Use Electric Water Heater designed for continuous hot water without a holding tank. Its compact size makes it suitable for under-sink or other space-constrained installations.

Featuring efficient heat exchangers and a connecting pipe, the AE-115 provides quick and reliable hot water delivery. It is equipped with a water filter screen that should be checked annually to maintain optimal performance.

Safety features include an inlet water isolation valve and a flow regulator to prevent damage to the flow transducer. For added peace of mind, the heater should be blown out with low-pressure compressed air before potential freezing conditions to minimize the risk of freeze damage.

Use & Care
17.25 kW 2x240 Volt Point-of-Use Electric Water Heater
Model Number AE-115
Use
For heating water without a holding tank for continuous hot water.
Care
Draining the heater
Due to the shape of the heat exchangers and connecting pipe, it is extremely difficult to get all of the water out of the
heater. Follow the procedure below to best minimize the chance of freezing:
1. Disconnect electric supply.
2. Disconnect cold and hot water pipes from fittings on bottom of heater. Allow water to drain out (have a
catch basin ready). After allowing all water to drain out, the heater should be blown out with low pressure
compressed air to remove as much water as possible from water heater modules. Bursts of air work better
than continuous flow.
Remember, these suggestions are only made to help minimize the potential for freeze damage and are not to be
construed as the guaranteed method for dealing with freeze possibilities.
3. Check inlet water filter screen once a year.
4. Check that the power is switched off at the circuit breaker panel.
5. Shut off the installer supplied cold water isolation valve to the heater. If one is not installed, install before
proceeding.
6. Open nearest hot water tap to relieve pressure in the plumbing lines. Position a bucket under the cold
water inlet connection of the heater to catch any water that may drain.
7. Disconnect the cold water plumbing connection from the inlet (bottom right of heater) to access filter
screen. Remove filter, clean with water and inspect for damage. If the filter is at all damaged, it should be
replaced. Replace the filter into the inlet housing DO NOT leave the filter out.
8. DO NOT remove the flow regulator (located behind the filter).
9. DO NOT clear the filter by back flushing. NEVER use an air line to blow out the heater (the flow transducer
will be permanently damaged).
10. Before switching power back on, open all hot water taps and inspect each tap to ensure all air in the lines
has been purged out. With the air purged and taps still flowing, turn on all circuit breakers supplying the
water heater.
11. Close all hot water taps and proceed for normal operation.
