Installation instructions

3 Installation instructions
The ES2.5 and ES4 water heaters are designed to be installed
under the sink.
3.1

Water Chemistry Requirements

The chemistry of the water supplied to the water heater may
affect efficiency, and may cause damage or premature failure to
the appliance and associated equipment. Water chemistry
must be analysed by a professional to determine if it is
necessary to treat the water, and if treatment is required the
professional should provide advice on a suitable solutions.
It is the responsibility of the installer to ensure that the
appliance is supplied with water that is potable
corrosive chemicals, sand, dirt, and other contaminants, and is
within the parameters shown in the Water Chemistry
Requirements Table below. In addition, operating temperatures
above 135°F will accelerate the natural accumulation of lime
scale and potentially shorten the life of the appliance.
Failure of the appliance due to lime scale build-up, and/or being
supplied with water that is outside of the required chemistry
parameters, is NOT covered by the warranty.

Table 3
1) Potable water is defined as drinkable water supplied from
utility or well water in compliance with EPA secondary
maximum contaminant levels (40 CFR Part 143.3). lf the
water contains contaminants higher than outlined by the
EPA, water treatment is recommended and more frequent
maintenance may be required. If you suspect that your
water is contaminated in any way, discontinue use of the
appliance and contact a licensed professional for
assistance.

Mounting the heater

3.3.1 Wall mounting
NOTICE:
The ES2.5 and ES4 water heaters come equipped with a power
cord.
▶ Ensure the circuit breaker supplying the electrical outlet for
the water heater is properly sized to handle the load of both
the water heater and another appliance (e.g. dishwasher).
See Table 2 for water heater electrical specifications.
▶ Fasten the supplied mounting bracket to the wall.
NOTICE:
Material damages!
▶ Use screws that are suitable for the wall material and the
weight of the heater when filled with water.
▶ Hang the water heater on the bracket.
▶ Tug down wards on the heater to ensure that both "fingers"
of the bracket are seated in the mounting slots.
3.3.2 Floor mounting
▶ Heater can sit on floor.
3.4

Pipe connections

▶ Connect the cold water inlet pipe to the inlet tapping
(marked with a blue ring).
▶ Ensure a isolation valve is installed on the cold water supply
to the water heater.
▶ Connect the hot water outlet pipe to the outlet tapping
(marked with a red ring).
The model ES8 can be piped horizontally from the side or
vertically from the top.
Horizontal installation - ES8 Model Only
If you wish to install the unit horizontally, with the piping
connections on the right side:
▶ Install supplied brass plug into tap between hot and cold
water connections.
▶ The supplied Temperature and Pressure Relief Valve will
need to be installed on top. See location of T&P relief valve
in Fig. 7.
