7.1 WARNINGS
IF WATER ISSUES FROM THE TEMPERATURE/PRESSURE RELIEF VALVE ON THE
MEGAFLO UNIT REFER TO SECTION 7.4 FIRST. IF THIS DOES NOT RECTIFY THE
FAULT SWITCH OFF ELECTRICAL SUPPLY TO THE IMMERSION HEATER(S) (DIRECT
UNITS) OR SHUT DOWN THE BOILER (INDIRECT UNITS). DO NOT TURN OFF THE
WATER SUPPLY. CONTACT A COMPETENT INSTALLER FOR UNVENTED WATER
HEATERS TO CHECK THE SYSTEM.
DO NOT TAMPER WITH ANY OF THE SAFETY VALVES FITTED TO THE MEGAFLO
SYSTEM, IF A FAULT IS SUSPECTED CONTACT A COMPETENT INSTALLER.
7.2 TEMPERATURE CONTROL
IMMERSION HEATERS
A combined thermostat and thermal cut-out is provided for each immersion heater. The
thermostat is factory set to give a water storage temperature of approx. 60
o
C, however
it can be set to control between 10
o
C and 70
o
C. This will usually have been done during
installation. Adjustments can only be made by opening the terminal cover(s), DO NOT
remove the cover(s) without first switching off the electrical supply. The temperature adjust -
ment is made by inserting a flat bladed screwdriver in the slot in the disc on top of the
thermostat and rotating (see Figure 10).
If in any doubt consult a competent electrician.
INDIRECT UNITS
Indirect units (CL models) are fitted with an Indirect Thermostat which controls a 2-port
motorised valve and hence the temperature of the water in the Megaflo unit. The thermo -
stat is factory set to give a water storage temperature of approx. 60
o
C, however it can be
set to control between 10
o
C and 70
o
C, this will usually have been done during installation.
Adjustments can only be made by opening the terminal cover. DO NOT remove the cover
without first switching off the electrical supply. Temperature adjustment is made by inserting
a flat bladed screwdriver in the adjustment knob located on the front of the thermostat
mounting bracket (see Figure 12) and rotating. At the minimum position the temperature
will be approx. 10
o
C. The adjustment range 1 to 5 represents a temperature range of 30
o
to 70
o
C
If in any doubt consult a competent electrician.
DO NOT bypass the thermal cut-out in any circumstances.
7.3 FLOW PERFORMANCE
When initially opening hot outlets a small surge in flow may be noticed as pressures stabi -
lise. This is quite normal with unvented systems and does not indicate a fault.
In some areas a cloudiness may be noticed in the hot water. This is due to aeration of the
water, is quite normal and will quickly clear.
