UNCLEAR OR IF THE REQUIREMENTS CANNOT BE FULLY MET.
PLEASE LEAVE THESE INSTRUCTIONS WITH THE USER AFTER INSTALLATION.
INSTALLATION
WALL MOUNTING (refer to diagram A).
The unit is designed to be wall mounted and must be tted at least one metre above the
highest draw-off point thus ensuring a good ow. It is important that sufcient clearance is
allowed to ensure access to the ball valve assembly.
The wall xing points will accept 8mm bolts which should not be less than 50mm in length.
ALWAYS ENSURE THAT THE WALL IS SUFFICIENTLY STRONG TO CARRY THE WEIGHT
OF THE UNIT WHEN IT IS FULL OF WATER.
PIPEWORK CONNECTIONS (refer to Diagram B).
The installation must conform to all local authority byelaws. The cold water supply and warning
pipe (overow) assembly can be connected to either side of the unit. The respective apertures
are pre-formed in the outer case and these should be used as guides for cutting through the
cold water tank. A 22mm hole is required for the inlet and a 27mm hole for the warning pipe.
An isolating valve must be tted to the cold water mains supply to allow for servicing.
FITTING TO THE COLD WATER TANK (refer to Diagram C).
The HYCO Apollo series of water heaters are supplied with all the components that are required
to comply with the WRC bylaw 30. The arrangement of these should conform to Diagram C.
The lter and breather assembly is a push snap-t connection and should be tted to the lid in
the aperture provided.
The warning pipe assembly (overow) has three components. The threaded elbow (tank
connector) is inserted through the hole that has been cut, and tightened with the nut and
sealing washer on the inside of the tank.
The 90o bend internal “dip tube” is pushed rmly into the connector facing downwards. The
warning pipe (overow) screen is located securley into the downwards external connection of
the connector.
The ball valve assembly is tted as required, adjusting the oat to ensure that the water level
in the tank does not exceed the water level line.
NOTE: after installation, replace lid and secure with the retaining screw supplied.

ELECTRICAL CONNECTION
The Installation should be carried out by a suitably qualied person in accordance with BS 7671
(IEE) wiring regulations.
A double pole isolation switch having a contact separation of greater than 3mm should be tted
to allow for servicing.
IMPORTANT: The unit MUST be full of water before switching on the electricity supply.
The HYCO Apollo water heaters are all tted with a 3kW heating element. The heating element
is located at the base of the unit. The heating element incorporates dual thermostats that are
linked to act as a control thermostat with an over-temperature safety cut-out. The thermostats
are factory set to 50oC for the control thermostat and 70oC for the cut-out thermostat.
The control thermostat should NOT exceed 60oC and the 20oC differential between the control
and cut-out thermostat MUST be maintained.
The supply cable should be securely clamped before replacing the heating unit’s own cover AND
as it passes through the gland in the element housing cover.
If during normal service, the cut-out thermostat operates rst establish the reason for
operation. Possibly a wrongly set control thermostat. Switch off the electricity supply before
removing the element housing cover. Correct the problem and then press the button to reset
the cut-out thermostat. Replace the heating unit cover and the element housing cover before
switching on the electricity supply.
