Page 5: Features And Benefits
Congratulations on purchasing the technologically advanced, temperature controlled, Rinnai Hot Water System. Rinnai water heaters will NEVER RUN OUT of hot water. As long as electricity, water, and gas supplies are connected, hot water is available when hot water taps are open. -
Page 6: Important Information
Do make sure that the tap is turned off tightly. This approach can be extremely valuable because it requires a Do consider setting your Rinnai one time action for a long term Water Heater at a maximum reduction in risks of scalds. - Page 7 IMPORTANT INFORMATION Always check water temperature before Hot water may go cold without warning at use. very low water flows (less than 3 l/min). OFF! Refer to warning about hot water on page 6 for important safety information. The delivered water temperature is If freezing temperatures are expected, turn controlled automatically.

Page 9: Temperature Controls
Adjustments to the operation of your hot water unit can be made with any of the Temperature Controllers. Each Temperature Controller can be individually programmed. Up to four Universal and/or Deluxe Temperature Controllers can be fitted with Rinnai water heaters. Universal Controllers allow temperature selection only and one comes as standard with some of the water heaters, Deluxe Temperature Controllers are always an optional extra. - Page 10 TEMPERATURE CONTROLS Remote temperature controllers provide control over the water temperature. Rinnai water heaters can be operated with 1, 2, 3, 4 or no temperature controllers. The MC-91-3A controller can be locked by pressing the Transfer button and the up-button together for 5 seconds. A beep will sound confirming that the controller is locked.
- Page 11 The Digital Monitor will go out. If hot water taps are opened when the Rinnai HDC is off, cold water will flow from the taps. If the system is to be left off over the winter be sure to drain it down if there is a possibility of freezing temperatures.

Page 16: Recirculation Mode
RECIRCULATION MODE The Rinnai water heater has the ability to control a recirculation pump. Two modes are available, Economy and Comfort, which recirculate the water in the plumbing system to provide hot water more quickly when a tap is opened. - Page 17 The Rinnai water heater should be turned on. Pump recirculation begins when the water heater is turned on. The Rinnai inlet and outlet thermistors measure the water temperature. The water heater produces hot water at the temperature setting. If the inlet thermistor detects abnormal temperature then diagnostic code 51 is generated and the pump will turn off.
