AVERAGE COLD WATER TEMPERATURE SUMMER 80°F WINTER 70°F. OUT-
LET TEMPERATURE EQUALS INLET TEMPERATURE PLUS TEMPERATURE
RISE. TEMPERATURE RISES ARE BASED ON kW LOADING AT 240 VOLTS
ARE SHOWN ABOVE. TEMPERATURE RISES IN EXCESS OF 110°F ARE NOT
RECOMMENDED.
Low Voltage Example
A reduction in input voltage will result in a reduction in temperature. Model
94805005 connected to a 220 volt supply with a flow rate of 0.75 GPM will result in a
53°F temperature rise instead of a 63°F temperature rise. To increase temperature,
reduce water flow rate.
Important Information
2.1.
Products designed by Santon are to British and European and UL Standards.
These appliances are safe and without risk, provided they are installed, used and
maintained in good working order in accordance with our instructions and
recommendations.
2.2.
Please read and understand these instructions before starting work and retain
them for later use.
2.3.
DO NOT operate the appliance if it is frozen, or suspected of being frozen. See
fault finding table.
2.4.
These heaters are of the closed outlet type (unvented pressure system) and
are suitable for connection to normal cold water mains supplies up to a maximum of
0.5MPa (5bar).
2.5.
DO NOT operate the appliance if:
1.
Water ceases to flow during use.
2.
Water has entered inside the unit because of an incorrectly fitted cover.
3.
If the appliance is damaged.
2.6.
ISOLATE the electrical and water supplies before removing the cover.
2.7.
ISOLATE the electrical and water supplies BEFORE proceeding with
installation or servicing.
Water Requirements
3.1.
The heater must be connected via the pressure relief valve to a cold supply
having a minimum pressure of 0.1Mpa (1bar) and a maximum of 0.5Mpa (5bar).
Both inlet and outlet connections are suitable for 5/8" diameter copper pipe. Outlet
pipe from unit may reduce to 10mm diameter to improve performance.
3.2.
The tee piece and expansion relief valve must be situated where shown and
the relief valve discharge port plumbed via an air break (tundish) to a safe, visible
place where there is no risk to persons.
3.3.
The discharge pipe must fall continuously from the valve outlets and be
unobstructed.
