IMPORTANT
It is a NSW requirement and may be a requirement in other states that a Warm Water System must
be registered by the owner of the building with the local council or regulatory authority.
Notice to Victorian Customers from the Victorian Plumbing Industry Commission.
This warm water system must be installed by a licensed person as required by the Victorian Building
Act 1993. Only a licensed person will give you a Compliance Certificate, showing that the work
complies with all the relevant Standards. Only a licensed person will have insurance protecting their
workmanship for 6 years. Make sure you use a licensed person to install this water heater and ask
for your Compliance Certificate.

GENERAL
This warm water system is designed for the purpose of providing potable water. Its use in an
application other than this may shorten its life.
The Apricus Tempermate Warm Water System provides water at a safe and usable temperature in a
situation where the control of the temperature of the water discharging from an outlet is of the
utmost Importance i.e. within hospitals, schools, aged care facilities, etc. This type of system is
intended mainly for use in applications with set temperature between 43-50°C. The valve is designed
to prevent the flow of water discharging from the mixed water outlet in the event of the failure of
either hot or cold supply.
The Apricus Tempermate utilises one or more Caleffi 2522TM series high performance thermostatic
mixing valves that have been specifically designed and manufactured to meet the requirements of:
“AS 4032.1 Thermostatic Mixing Valves-Materials, Design and Performance requirements”. This
particular series of valves can be used with high temperature water in solar applications.
If this warm water system is to be used where an uninterrupted warm water supply is required, you
should ensure that the warm water system is designed in such a way that you have back up
redundancy. We recommend you seek advice from your plumber or specifier about your needs with
regards to building redundancy into your warm water system.
BENEFITS OF WARM WATER SYSTEMS
Centralised mixing valves provide several benefits over point of use;
•Reduces the installation cost of multiple valves, as well as reducing the cost and
inconvenience of having to service multiple units
•Maintenance can be managed from one central location, usually at the hot water plant room
•Reduced interruption of water supply through improved maintenance scheduling
•Improved aesthetics from requiring mixing valves under cabinets, in walls etc
•Energy savings are achieved with warm water systems by reducing the circulation
temperature, thereby reducing the heat loss through pipes.
SAFETY
The Apricus Tempermate can give stable operation provided it is installed, commissioned and
maintained as per the recommendations outlined in this manual. This unit cannot be considered as
an alternative to adequate duty of care during its use and operation.

OPERATION
The Apricus Tempermate warm water system is a centralised warm water plant which allows warm
water to be circulated around a building.
The system utilises a thermostatic mixing valve(s) which mixes hot and cold water in such a way as to
maintain the set temperature of the mixed water at the outlet. The TMV thermostatic element is
fully immersed into the mixed water. It then contracts or expands causing movement of the piston,
closing either the hot or cold inlets, regulating the flow rates entering the valve. If there are
variations of temperature or pressure at the inlets, the internal element automatically reacts
attempting to restore the original temperature setting.
The Apricus Tempermate Warm Water Unit may have one, two, three or four TMV’s depending
upon the unit selected. On models with more than one TMV, the valves are manifolded in parallel
and operate independently of each other to supply warm water to a common outlet.
Draw-off Mode
When a warm water outlet is opened, hot and cold water flows through the thermostatic mixing
valves, and to the opened warm water outlets.
Recirculation Mode
When no warm water is being drawn from the system, the warm water circulates through the unit
and continues to keep the water at the set temperature.
The returning water splits at the cold water inlet with a proportion returning to the TMV’s cold
inlets, and the remaining proportion returning to the TMV’s hot inlets. The proportion returning to
the hot inlets does so by flowing back up the cold water inlet pipe to the cold water supply line and
on to the boiler where it is reheated and returned to the TMVs via the hot water pipe.
THERMAL SHUT OFF
In the event of a failure of the hot or cold supply, the piston will shut off, stopping water discharging
from the mixed water outlet. The TMVs require a minimum temperature differential from hot inlet
to mixed water outlet of 10°C to ensure the correct operation of the thermal shut off feature.
