Example of Installation with a Storage Tank and Recirculation SystemThe pump will push water through the Multi-System to heat up the tank.When the return temperature is high, the flow within the device will be limited to 1.3 GPM*.* For the set temperature of the remote control, use the temperature (of the thermostat) + about 9°F.* To achieve the highest recovery, size the storage tank circulation pump for maximum capacity.( N-132M: 12 GPM (each) @ 50 ft. of head (160°F setting or less), N-084M: 7.4 GPM (each) @ 40 ft. of head(160°F setting or less) + piping losses through the system). Verify the supply pressure to the units is at least 30 PSI.
