Condensing Pool Heater
2
01/07/09
In Heating Mode.
It normally shows the boiler temperature but also
shows the Setting Temperature when the Heating
Temperature Knob is adjusted.
If the display alternates a temperature with ‘SEr’ it is
recommended that the Heater is serviced, it will
continue to function.
The Display is also used for commissioning and
diagnostic purposes. (Page 16)
Heating Demand LED
- GREEN
(Only in use when heating system connected)
Off - There is no Heating Demand , heating is
switched off.
On - There is a Heating Demand , heating is on but
not yet up to temperature.
Flashing - The Heating Demand is met , heating is
up to temperature.
Heating Temperature Control Knob
(Only used when heating system connected)
Off - There is no Heating Demand, heating is
switched off.
Normal - Normal setting for heating, it can be
adjusted lower if required.
(NOTE: The Heater is supplied set for Pool Priority.
It will satisfy the Pool Temperature before providing
Heating. To change the priority, see Page 16,
Commissioning Section, of these Instructions)
Pool Pump Pressure LED - YELLOW
On -
If the pump is running there is insufficient
pressure, possibly due to a blocked Pool Filter. The
Heater will not run.
Lockout
-
Left Red LED, Display “GAS”
On - This indicates the Heater Gas Ignition Control
has locked out. Press the Lock/Reset Button to start
the Heater again. If this problem persists this should
be investigated by a Service Engineer.
Condensate
-
Right Red LED, Display “HI”
This indicates that the Condensate drain is blocked
and the Heater has shutdown. When the blockage is
cleared for the Heater will operate again.
Overheat
-
Flashing Red LED, Display “OH2”
Flashing - This indicates the Heater has overheated
and it has shutdown. Wait for the Heater to cool then
press the Lock/Reset Button to start the Heater
again. If this problem persists this should be investi-
gated by a Service Engineer.
Pressure Gauge -
This should be between 1.5 to
2.5 bar, repressurise if too low.
General Information
Water Pressure Switch
A pool water pressure switch is provided in the
heater to shut off the burners in the event that water
supply to the heater is interrupted. The water
pressure switch should be checked and adjusted for
proper operation by a qualified service person at the
time of installation, and thereafter checked at each
service.
WARNING: Operation of the heater without water
circulation will cause rapid and severe damage to
the Heater.
Water Temperature Settings
The Heater is designed to provide the maximum
amount of heat to the pool up to one degree below
the set temperature. For that last degree it reduces
the power to maximise control. For certain installa-
tion designs, if the pool is used before it is up to set
temperature, the water entering the pool from the
Heater could be warmer than the pool. This is not a
fault but part of the design. It will reduce for the final
degree up to set temperature.
Chemistry
Please see page 3 for the maximum levels and the
procedural requirements for adding chemicals
Cleaning
It is recommended that periodically the casing is
cleaned and sprayed with WD40 or similar liquid, and
any exposed threads are lightly coated in grease.
Service & Maintenance
It is recommended that the Heater is serviced every
2000 hours of operation, for normal use this is about
12 months. The control will alert when you when it
reaches this period by its display, ‘SEr’ alternating
with the temperature.
It is a mandatory requirement that any gas work
carried out must be by a registered engineer with an
appropriate accreditation.
Winterisation
Provided the Mains Electricity and Gas are con-
nected and on, the Heater will fire to prevent it
freezing, it will use the space heating circuit for this.
If the Pool and Heater are not going to be used for
the cold winter months it is recommended that the
equipment is winterised. Contact your pool installer
for help with this.
Failure to run or winterise the Heater during a period
of freezing could cause damage to the Heater which
will not be covered by your warranty.
