INSTALLATION AND MAINTENANCE
All metallic components of the machine, in direct contact with
drinking water are manufactured from high quality 304 grade
stainless steel, or non ferrous materials, providing maximum
resistance to corrosion.
CONSTRUCTION
To comply with recommendations
from the Health and Safety Executive
it is important that due consideration
be given to safe operation of the
controls of the boiler. The boiler should
therefore be mounted in such a manner
that the operator can stand directly
facing the machine with the controls at
a recommended height from the fl oor to
the draw-off tap handle of 1200mm +/-
100mm. Consideration should also be
The boiler must be installed in a location where access is
restricted to operators that are suitably trained, or where
untrained operators of the machine can be supervised by trained
personnel.
Calomax products have been tested and found to comply
with the requirements of the Water Supply (Water Fittings)
Regulations 1999 for England and Wales Water Bylaws
2000, Scotland and the Water Regulations Ireland.
given to the servicing requirements of the machine. The maximum
and minimum ambient operating conditions must be between
5 °C and 35 °C. The appliance is not suitable for installation where
a water jet could be used. Install the boiler on a surface or wall
suitable for the working weight of the boiler. Allow clearance for
ventilation and for the easy removal of the outer casing lid and
front panel. Calomax ltd recommend a minimum clearance of
50mm on all sides of the boiler. A suitably qualifi ed engineer must
install this unit. Plumbing and electrical installation work may be
involved.
To comply with the U.K. Water Supply Regulation a single checkvalve must be fi tted to the supply. BEFORE CONNECTING, THE
SUPPLY PIPE MUST BE THOROUGHLY FLUSHED OUT TO
ENSURE THAT FOREIGN MATTER DOES NOT BLOCK OR
ENTER THE SOLENOID VALVE
The boiler must be connected to a potable water supply using
the food grade hose where provided, or rigid 15mm pipe in
a manner which complies with UK water regulations via an
appropriate isolating valve. The supply must provide a constant
pressure of between 20 KPa and 1000 KPa (0.2 to 10 Bar).
If the water supply contains excessive solids in suspension it is
recommended that a fi ne mesh “in line” water fi lter is fi tted in the
pipe work. Failures due to scale and sediment are not covered by
the warranty.

VENT & OVERFLOW
The vent / overfl ow pipe must be extended and laid with a
continuous
fall,
discharging to a safe and visible point. The pipe should not be
directly connected to a closed waste, as taste problems may occur and
should never be allowed to become blocked or restricted.15mm copper or
‘Speedfi t’ pipe should be used. The drip tray kit provided with the counter
top models allow the option of plumbing the overfl ow pipe to discharge
into the drip tray and then plumbing the drip tray to a safe and visible
point of discharge. If the machine is operated without the overfi ll pipe
being extended as advised, any subsequent damage incurred will be the
responsibility of the installer.

If the boiler is required to
drip or overfl ow into the
drip tray, the confi guration
of pipework may be altered
as follows. Remove the
machine front panel and
unclip the pipework elbow.
Carefully pull the elbow
in the direction of the
arrow, out of the silicone
connecting tube on the
end of the main water pipe.
The silicone connecting
tube will now direct water
into the drip tray.
