Installation Requirements; Operation Instructions - Atmor 900 series Installation Manual

OPERATION INSTRUCTIONS

1. Your new Instant Water Heater is flow activated. Simply place one or both switches in the ON position
and turn on the hot water tap. You will need to allow at least 1.5 liters per minute to flow through the unit
in order to activate the Instant Heating System. Run water through the heater for a few minutes.
2. Be sure to every so often clean the spray head of sediment to assure a smooth water flow.
3. Be sure to every so often clean the incoming water filter.
4. The maximum operating water pressure is 8 atmospheres or 115 PSI. This is well above the usual 3
atmospheres or 40 PSI most municipal water systems provide.
5. Be sure to install your Instant Water Heater in a heated location. It cannot be installed where temperatures
drop below freezing.
6. There are two ways to adjust the hot water temperature. One is by adjusting the flow, the other is by
changing the electrical settings on the unit. The slower the flow, the more time the unit has to heat the
water, resulting in higher water temperatures. Adding more rings to the water flow restrictor will limit the
flow and increase the output water temperature. You may choose the low, medium or high settings on
the heater, as required to achieve the water temperature desired.
Setting 0/OFF: No heating, lamp will not light.
Setting 2: Medium heating, lamp 2 will light.
For 220V - 240V 3.5kW unit only positions 0 & 1 are available.
7. During the summer, it is recommended using only setting 1 or 2 for device with 220V-240V 13kW output.
