WIRING
ALL FIXED ELECTRICAL WIRING MUST BE COMPLETED BY A SUITABLY
QUALIFIED PERSON.
1. Check the kilowatt rating of the heater. Ensure the correct size cable is being used.
2. The cable entry point is via one of three knockouts provided on the underside of
the heater head. Use the correct size grommets and conduits when installing.
3. Check that wiring to terminal blocks is secured firmly and to the correct terminals.
4. The temperature rating of supply cord connected to the equipment shall not be
less than 95ºC.
WARNING! Ensure that an electrical isolation switch is located
with easy access so the heater can be switched off in an
emergency.
PLUMBING
1. The heater body may be plumbed so the water flow can be in either direction.
The head of the heater may be turned to any of the four keyed directions (90°) to
give best access to the thermostat control.
3. When connecting pipework to heater make sure the ‘O’ rings are properly seated
in the mac union fitting. NB. Hand tighten only. Using tools will distort the fittings.
4. Make sure the heater is mounted on its stand or secured firmly so that vibration
is minimised.
5. It is recommended that the pipework has shut off valves so the heater head can
be removed for service without loss of water or downtime due to reheating.
2. When installing the heater head the ‘O’ ring must be carefully
located on the element carrier and NOT in the body. When fitting
head make sure the ‘O’ ring doesn’t become dislodged and fall
into the body. To assist assembly it is recommended that a light
lubricant be used on the inside of the body barrel to help the
components to slide together easily. REFER FIG.2 & 3.
