The "Smartstart®" system heats the water in the pipework water

connected between the water heater and the hot water outlets before

any outlets are opened using the 'flow and return' pipework principle.

This results in water savings and reduced waiting time for heated water

delivery from the outlet when opened.

Traditional 'flow and return' systems usually keep the water in the

pipework heated continuously. The Smartstart® system however, only

heats the water before the outlet is opened. This results in significant

energy savings because water is not heated unncessesarily whilst

retaining the benefits of traditional flow and return systems.

A schematic of the Smartstart® system installed in conjunction with a

Rinnai continuous flow water heater and temperature controller is shown

in Fig.2 below.

The Smartstart® system works as follows:

Before hot water is required, the user activates the Smartstart® system

by pressing the 'preheat' button on the temperature controller.

This activates the Smartstart® system and the integral pump is switched

on.

Water flows from the pump and passes through the water heater. This in

turn activates the water heater burner and water in the flow and return

heating loop begins to heat.

When the Smartstart® control module senses that the water in the full

length of the flow and return heating loop has been heated, the pump

and water heater stop operating.

The user opens the desired hot water outlet. Preheated water will be

delivered from the flow and return heating loop to the outlet.

Location and clearance requirements for the Rinnai continuous flow

water heater are detailed in the Installation Instructions supplied with it.

The Smartstart® module weights 7.5 kg and the wall or structure on

which it is to be mounted must be capable of supporting the combined

weight of the Smartstart® unit, water heater and any associated

pipework.

Both the water heater and Smartstart® module must be in an accessible

location. Sufficient clearance shall allow access to, and removal of, all

serviceable components. Water heater and Smartstart® modules should

not be mounted higher than 3.5 meters from the ground or floor level

unless the customer can arrange permanent and safe access or can

arrange another means of access, for example, by means of scissor or

boom lifts.

The Smartstart® module is usually located below the Rinnai water

heater. However, it can be mounted anywhere within the return loop.

As the communication cable is only 1.0 metre in length you will have to

extend the original cable if installed further away than 1.0 metre from the

Rinnai continuous flow water heater.

An AC240V, 10 Amp weatherproof external earthed power point shall be

provided adjacent to the Smartstart® module (the power cord is 1.5

metres long).

regulatory requirements which exist in your area. Applicable publications

may include:

•

THE SMARTSTART® SYSTEM MUST BE MOUNTED ON A VERTICAL

WALL OR STRUCTURE.

THE SMARTSTART® SYSTEM CANNOT BE USED BY ITSELF OR WITH

ANOTHER MANUFACTURERS WATER HEATER OR WATER

CONTROLLERS.

It is Certified and compatible with the following Rinnai continuous flow water

heater models:

At least one water controller model MC-91Q must be used in conjunction

with the water heater and the Smartstart® system. Alternatively, if Water

Controllers cannot be used a manual activation (momentary or ‘doorbell’

type) switch is available. Contact Rinnai for more information.

The installation of the water heater and water controllers must be performed

in accordance with the Installation Instructions supplied with the water

heater.

The Smartstart® system is designed for domestic installations. However, it

may be suitable for certain non domestic installations. Contact Rinnai for

more information.

SMARTSTART® KIT CONTENTS (Fig.1)

The Rinnai Smartstart® kit comprises an enclosure containing circulating

pump, water connections for cold water inlet, cold water outlet and heating

loop return, control wiring and printed circuit board. It is fitted with an electric

power cord with three pin plug suitable for connection to a 240 V 10 Amp

GPO. It is also fitted with a control lead for connection to the Rinnai

continuous flow water heater.

The Rinnai Smartstart® kit does not include:

Alternatively, the water heater and Smartstart® module can share the same power point provided it is of the dual outlet type. Approved pressure limiting and expansion control valves must also be fitted. A combination pressure limiting and expansion control valve may be used. The pressure limiting valve must be rated at 500 kPa. The Expansion Control valve must be rated at 700 kPa. OTHER RATING COMBINATIONS ARE NOT SUITABLE! Double adaptors and extension leads must not be used.
