2.1 GÉNERAL INFORMATION
The INSTOMAX™ is an instantaneous water
heater. It is composed of a thermal mass
reservoir filled either by water or other liquid and
a copper heat exchanger immersed in the
thermal fluid. Domestic fresh water passing
through the heat exchanger is heated by the
thermal fluid. Therefore the INSTOMAX™ has
two separate hydraulic circuits: The reservoir
(thermal mass) side and the domestic hot water
side located inside the heat exchanger.
2.2 LOCAL INSTALLATION
REGULATIONS
This water heater must be installed in
accordance with these instructions and must
conform to local codes, with the current edition
of the National Plumbing Code and the National
Electric Code. In any case where instructions in
this manual differ from local or national codes,
the local or national codes take precedence.
2.3 CORROSIVE ATMOSPHERE
The water heater should not be located near an
air supply containing halogenated hydrocarbons
or high humidity. Such localisation would void
any water heater warranty.
2.4 SHIPMENT INSPECTION

Section 3: INSTALLATION
The manufacturer’s warranty does not cover
any damage or defect caused by installation
or attachment or use of any special
attachment other than those authorized by
the manufacturer into, onto, or in
conjunction with the water heater. The use of
such unauthorized devices may shorten the
life of the water heater and may endanger life
and property. The manufacturer disclaims
any responsibility for such loss or injury
resulting from the use of such unauthorized
devices.
3.1 SAFETY MEASURES
All domestic and commercial installations will
include a pressure relief valve limiting the
operating pressure to 207 kPa (30 psi) for the
INSTOMAX’s reservoir.
This INSTOMAX™ electric water heater is
designed for a maximum operating temperature
of 88°C (190°F). Typically, the tank’s thermal
mass liquid is tap water. If allowed by local
authorities and applicable code, a 30 to 50%
water and propylene-glycol blend can be used
for installation where supply fresh water
pressure is above 240 kPa (35 psig). Specific
equipment designed to avoid backflow to the
main water supply network might be required by
local installation codes.
3.2 EMPLACEMENT
The INSTOMAX™ water heater should be
installed in a clean, dry location. Long hot water
lines should be insulated to conserve water and
energy. The water heater and water piping
should be protected from exposure to freezing.
INSTOMAX™ water heaters must be installed
vertically. Use the adjustable feet to level the
unit.
The INSTOMAX
TM
water heater must be located
or protected so as not to be subject to physical
damage, for example, by moving vehicles, area
flooding, etc..
All models can be installed on combustible floors
and in alcoves. If the water heater is to be
installed in a restaurant or other location where
the floor is frequently cleaned, it must be
elevated to provide at least 150mm (6 inches) of
clearance from the floor to comply with NSF
International recommendations.
The room temperature must be maintained
between 10C (50F) and 33°C (90°F).

3.5 PIPING (see figures 1&2 for
identification and locations of components)
3.5.1 Tank pressure relief valve
The tank is protected with a pressure relief valve
set at 207 KPa (30 psig). NEVER replace this
pressure relief valve by a higher set pressure
one. Connect the supplied relief valve outlet
downward to insure that any expel water will be
directed toward a safe location. NEVER plug
the relief valve.
Piping diameter must not be smaller than the
pressure relief valve . The end of the piping
must be visible and not exposed to freezing.
3.5.2 Operating pressure control:
expansion tank:
The water heater is provided with a combination
pressure regulator / check valve allowing the
filling and pressurisation of the tank. The initial
pressure is generally of 83 kPa (12 psig).
In operation, water expansion will increase the
internal INSTOMAX™, pressure. Typical
operating pressure should be between 83 and
190 kPa (12 and 28psig) according to the tank
temperature.

Figure 3 : Basic piping lay-out.
The expansion tank supplied with the water
heater is to compensate for the water volume
expansion cause by the tank water temperature
rise.
Typically, the expansion tank is mounted on an
adjoining wall or ceiling and directly connected
to the tank 1/2NPT male connector specially
provided for this purpose.
3.5.3 Automatic air Vent
An automatic air vent used to eliminate any
entrapped air from the tank is provided and
factory installed on the INSTOMAX™ DO NOT
block or plug the air bleeder outlet. It must be
rapidly changed if it keeps leaking.
3.5.4 Domestic hot water connections
Both the domestic fresh water inlet and hot
water outlet are well indentified on the water
heater right side (HOT WATER OUTLET and
COLD WATER INLET). 3/4’’ NPT FEM fittings
are use for connections.
Use only clean new pipe for domestic water
connection. Local codes, regulations and
authorities having jurisdiction may required
specific pipe material to be used for
connections.
Insulate all pipes containing hot water,
especially in unheated areas.
A thermometer should be installed to indicate
the domestic hot water temperature at or near
the INSTOMAX™ domestic hot water outlet.
3.5.5 Expansion tank on the cold water
supply line
Determine if an equipment incorporating a flow
check valve is present on the cold water supply
line.
Such items may create a closed system and
prevents the water, as it is being heated, from
expanding back into the cold water supply line.
Pressure can build up within the water heater,
causing the pressure relief valve to operate
during a heating cycle. This excessive operation
can cause premature failure of the relief valve
and possibly of the water heater itself.

INSTOMAX
TM
Integrated instantaneous water heater installation, use and care manual (Revision Sept 2013) , Page 7.
Replacing the relief valve will not correct the
problem. One method of preventing pressure
build-up is to install an expansion tank on the
cold water supply line between the
INSTOMAX
TM
unit and flow check valve. Contact
your installing contractor, water supplier, local
plumbing inspector or plumbing supply house for
assistance.
3.5.6 Domestic hot water pressure relief
valve
The INSTOMAX™ is provided with a factory
installed domestic hot water pressure relief valve
factory set at 860 kPa (125 psig). Connect the
supplied relief valve outlet downward to insure
that any expelled water will be directed toward a
safe location.
Relief valve outlet pipe diameter must not be of
samller diameter than the relief valve outlet. The
end of the pipe must be visible and protected
from freezing.
3.5.7 Thermostatically controlled mixing
valve
The INSTOMAX™ is equipped with a factory
installed thermostatically controlled mixing valve.
This valve allows reducing, setting and
regulating the domestic hot water temperature at
a safe level. In order to adjust the mixing valve
to the desire temperature, create a demand for
domestic hot water, measuring the domestic hot
water temperature will indicate the adjustment
required.
3.6 ELECTRICAL
3.61 Main electrical power supply
The water heater electrical wiring and grounding
connection must be in accordance with the
National Electric Code or the local electric
installation code applicable.
It is the electrical technician responsibility to
insure that the electrical installation is in
accordance with the applicable code and
regulation.
Electrical power supply must be of a 240 volts or
208 volts single phase 60 Hz providing two
conductors (L1-L2) with a ground wire. The
installation must be protected by an appropriate
capacity breaker.
Since the INSTOMAX™ is available in different
power capacities; it is the electrical technician
responsibility to check the amperage rating
shown on the equipment identification sticker in
order to select the appropriate wiring and
breaker capacities. The wiring used can be
either of aluminum or copper, but must be rated
for a minimum of 90°C (190°F).

Section 4: OPERATION
SAFETY PRECAUTIONS
Be sure to read and understand the entire Manual before attempting to install or operate
this INSTOMAX™ unit. Pay particular attention to the following “General Safety
Precautions”. Failure to follow these warnings could cause property damage, bodily injury
or death. Should you have any problems understanding the instructions in this manual,
STOP, and get help from a qualified installer or technician.
4.1 GENERA INFORMATION
To meet domestic hot water needs, the aquastat
(s) temperature controller on this water is
adjustable up to 88°C (190°F) and regulate the
temperature of the liquid inside the tank .
However, domestic hot water temperature is not
controlled by these aquastat(s) but by the
thermostatic mixing valve located in the upper
section of the unit (see fig.1)
Domestic hot water over 52°C (125°F) can cause
severe burns instantly or death from scalds.
50°C (120°F) is the recommended starting point
for setting the control to supply general-purpose
hot water.
Safety and energy conservation are factors to be
considered when setting the water temperature of
the tank and domestic hot water temperature..
The most energy efficient operation will result
when the temperature setting is the lowest that
satisfies all the requirements
The following chart details the relationship of
water temperature and time with regard to scald
injury and may be used as a guide in determining
the safest water temperature for your applications
TIME TO SCALDING VS TEMPERATURE
RELATIONSHIP
Temperature Time to scalding
50°C (120°F) Over 5 minutes
52°C (125°F) 1-1/2 to 2 minutes
54°C (130°F) About 30 seconds
57°C (135°F) About 10 seconds
60°C (140°F) Less than 5 seconds
63°C (145°F) Less than 3 seconds
66°C (150°F) About 1-1/2 second
68°C (155°F) About 1 second
With kind permission from the Shriners Burn Institute
The thermostatic controlled mixing valve should
be adjusted by opening a domestic hot water
tap, measuring the water temperature with a
thermometer and by adjusting the
thermostatically control mixing valve accordingly.
There is a hot water scald potential if the
thermostatically controlled mixing valve for
reducing point-of-use water temperature is
damaged, not properly working removed or
by-passed.
Do not turn ON the water heater unless it is
filled with water. Do not turn ON the water
heater if cold water supply shut-off valve is
closed.
4.2 FILLING THE WATER HEATER TANK
Make sure the tank drain valves is closed. Open
the cold water valve supplying the water heater.
Bleed the air from the water heater tank by
opening the pressure relief valve located on top
the water heater tank while you are filling the
tank.
One the reservoir is filled, close the pressure
relief valve and allows the water heater tank
internal pressure to rise. Tank pressure should
stabilise at a value of approximately 83 kPa
(12psi).
4.3 FILLING THE DOMESTIC WATER
HEATER HEAT EXCHAGER
There is a heat exchanger located in the water
heater tank that separate the thermal mass fluid
(water) and the domestic hot water. This heat

exchanger containing potable water must be
filled.
Make sure that the heat exchanger drain cock is
turn off.
Open the nearest domestic hot water tap as well
as any control valve on the water heater outlet
(the copper tube at top the water heater).
The cold water supply to the unit shall be Open.
Close the domestic hot water tap as soon as
water flows out of it. Fix any leaks
Open every other hot water domestic hot water
paps in succession, in order to evacuate aire
from the distribution system.
4.4 TANK THERMAL MASS FLUID
(WATER) AQUASTAT TEMPERATURE
SETTING
Consider safety and energy saving while setting
the water heater tank temperature aquastat(s). It
is more energy efficient to set the tank
temperature as low as possible. But lowering the
temperature results in less storage of energy to
provide domestic hot water heater.
A minimum of 70°C (160°F) tank temperature
is recommended as a starting point to insure
a good supply of domestic hot water.
To adjust the temperature set point of the
aquastat turn the knob until the required value of
the desired temperature is aligned with the
reference point.
In usage, it may be found that the set tank
temperature needs to be increase in order to
supply all the domestic water needs. The tank set
temperature may be raised up to a maximum of
88°C (190°).
If the unit has two aquastats, set one of them
approximately 2C (5F) lower then the other one.
4.5 START UP PROCEDURE
1. Fill tank and heat exchanger as described in
sections 4.2 and 4.3.
2. Adjust temperature levels as described in
section 4.4
3. Turn ON the water heater electric breaker.
4. The water heater main contactor should
close with an audible snap sound, and all
elements should turn on, along with their
indicator light.
5. Tank temperature should gradually increase.
Time required for the INSTOMAX™ to reach
the tank water temperature set point vary
from 1 to 4 hours according to the water
heater power input.
6. Once the temperature set point is reach,
heating elements and their indicator light will
turn off.
4.6 THERMOSTATICALLY CONTROLLED
MIXING VALVE SETTING
A thermostatically controlled mixing valve
automatically regulates the mix of very hot and
cold water as required to provide safe domestic
hot water under variable conditions.
To adjust the mixing valve setting, carefully open
a hot water tap. Protect yourself against the
scalding. Measure the hot water temperature with
a thermometer. Mixing valve adjustment is
achieved by turning the mixing valve knob
clockwise to reduce the domestic water
temperature, contraclockwise to raise the
domestic water temperature,
Unless local regulation requires otherwise, a
50°C (120°F) is considered the best temperature
to reduce heat loss through the plumbing and
prevent scalding for young kid and senior citizen.
Generally residential dishwasher are provided
with their own water heating element and don’t
required hotter water.
Raising the domestic hot water outlet
temperature will not provide more domestic hot
water. In order to provide more domestic hot
water, the amount of energy in the water heater
tank need to be increase, this is achieved by
increasing the water tank temperature (maximum
88°C /190°).

Section 5: MAINTENANCE
5.1 INTRODUCTION
Regular water heater maintenance will ensure
trouble-free service for many years. It is
recommended that you set up and follow a
maintenance program. All component may fail
eventually. The use of incorrect replacement
parts or disregarding safety procedures and
warnings during repairs may reduce the boiler
safety level and shorten its useful life.
The owner should set up the following
maintenance program.
5.2 AT ALL TIMES
The water heater should be immediately
inspected in case of:
 Overheating or burn plastic odours are
detected.
 Water leak from the water heater or the
domestic hot water system is found.
If the hot water is leaking from the pressure relief
valve, it may indicate a problem with some
components of the systems. Immediate attention
and repair by a qualified technician are required.
NEVER CLOSE OR PLUG A PRESSURE
RELIEF VALVE.
5.3 YEARLY INSPECTION
Make sure that the power supply to the water
heater has been turn off at the circuit breaker
before attempting any work on the water
heater.
 Visual inspection of the water heater
electrical cabinet. Checks for leaks at the heating
elements, sign of overheating of electrical
components and wiring. Check for t proper
operation of the unit temperature control.
 Check the thermostatic mixing valve
proper operation by measuring domestic water
temperature at a domestic hot water tap with a
thermometer.
 Check for proper operation of the
automatic air vent, located on top of the water
heater, by removing its cap and by pressing on
the knob, releasing air until water began to be
expelled.
 Do not open the tank drain tap unless
repair to the water heater is required. Opening
the drain tap will eventually force fresh water into
the tank. This water will introduce oxygen diluted
in the fresh water. This oxygen will cause
corrosion of the tank internal surfaces, damaged
the reservoir and void the warranty.
 If repair is required, it should be
accomplished as soon as possible, by a qualified
technician and using genuine replacement parts.
The manufacturer’s warranty DOES NOT
cover problems caused by improper
installation or maintenance. If the safety valve
opens periodically, it may be due to the
expansion tank. Immediately call a qualified
technician to appraise and repair the problem.
