Viron Pool and Spa Heater Page 5

CHEMICAL BALANCE

It is imperative that correct chemical balance be maintained in your pool and spa water, otherwise
corrosion of your heater may occur. Corrosion of the heat exchanger voids warranty.

Your
local pool shop specialist or spa retailer can advise correct chemical balance. Your water should
be checked and maintained regularly by a pool water professional. As a guide the following
parameters may be used.

pH 7.6 to 7.8
Total Alkalinity 80 to 120 ppm
Calcium Hardness 150 to 250 ppm
Salinity 4000ppm max. Excessive salt can damage your heater.

You should test your water chemical balance at least on a weekly basis.

Excessive sanitiser can damage your heater. Chlorine should not exceed 3 ppm and bromine
should not exceed 5 ppm. Salt chlorinators, especially when used on spa pools or indoor or
covered pools, can easily produce excessive chlorine levels which will damage the heater
internals.

CORROSION PREVENTION IN HEATERS

All pool and spa heaters use copper or copper nickel to make their heat exchangers as it is the
most efficient material in transferring heat from the combustion chamber into the water. The
typical life expectancy of a well maintained pool/spa heater is between 5 and 12 years.

The addition of sanitisers (Chlorine, Bromine etc) and other water balancing and conditioning
chemicals can increase the rate of wear and tear on the heat exchanger and associated parts in your
heater.

There are three most common reasons for heat exchanger corrosion which can be avoided with a
little care and attention.

1. Excessive Sanitiser. This means too much Chlorine or Bromine in the water. Be careful, if
the level of Chlorine or Bromine is excessively high your test kit (and the pool shops) may not
read accurately or indeed may show a nil reading. Any time a salt chlorinator is operating for
extended periods, (when heating the swimming pool from cold), particularly if the weather is
overcast or the pool enclosed or covered, the Chlorine level may exceed normal levels. When
heating a Spa Pool, turn the chlorinator down or off for the duration of the heating period.

2. Out of balance water. The water balance is a combination of pH, total alkalinity, Calcium
hardness and temperature. Balanced water will help prevent corrosion of your heater. Balanced
water should be between 7.2 - 7.8 pH.

3. The addition of acid to lower pH. Acid must always be added in small quantities and spread
over the pool surface evenly, not added in to the skimmer

. Do not add a litre at a time, add a

cupful each day to lower your pH.

If you have a salt chlorinated INDOOR pool or COVERED pool be very careful of the level of
Chlorine being produced. If you use a salt chlorinated spa be very careful of the level of Chlorine
as the Chlorinator is usually sized for the pool and therefore should be switched off when heating

Viron Pool and Spa Heater Page 6

the spa. Leaving the chlorinator on can raise the chlorine level very rapidly in a small volume of
water.

These comments are intended as a guide only and are not definitive answers or recommendations
on pool water chemistry. Astral Pool’s intention is to provide a little understanding of the
potential problems of water chemistry and the dangers of corrosion to heaters (and other pool
equipment and fittings).

YOUR WATER SHOULD BE ADJUSTED & BALANCED PRIOR TO ANY CORRODED
PARTS BEING REPLACED.

DIGITAL THERMOSTAT OPERATION

DESCRIPTION

The sophisticated digital thermostat provides temperature read out, set point temperature,
operating status of the heater and any fault conditions.

TEMPERATURE DISPLAY

The temperature display indicates water temperature in the inlet of the heater. Therefore the pump
must be operating for an accurate pool or spa water temperature to be displayed.

Comfortable pool temperature is between 26˚C and 30˚C. Normal spa temperature is between
36˚C and 38˚C. To select your desired temperature press the up or down button repeatedly until
the desired temperature is reached.

To prevent rapid cycling of the heater, the thermostat has an inbuilt time delay which prevents the
heater from turning on for two minutes after the set point has been reached. If the time delay is
activated, the symbol “L” will be displayed on the LCD screen on the front of the heater. This is
part of normal operation.

Should a fault condition occur, the heater will lock out and prevent further heating. A lock out
condition is indicated by the symbols F0 to F9. To reset a lock out condition, turn the power off
for five seconds.

When the water temperature is heated to within 1 degree of the thermostat set point, the Viron
burner will modulate or turn down so that the set point is accurate maintained and not exceeded.
This prevents waste of energy typically associated with on/off burners. In addition, the set point
is maintained very accurately, so the when using your spa pool, you will notice very little variation
in water temperature.

Viron Pool and Spa Heater Page 7

DISPLAY SYMBOL INDICATION

Under fault conditions the thermostat will display a set of alpha numeric symbols to indicate the
status of the heater. The meaning of each symbol and action to be taken are listed as follows:

MAINTENANCE

It is recommended that you check the following at least every six months and at the beginning of
every swimming season.

1. Examine the flue outlet and panel louvres for blockages. Make sure there are no obstructions

to the flow of air to or from the appliance.

2. Keep the heater area clear and free of combustibles and flammable liquids. Chlorine should

not be stored in the vicinity of the heater. Chlorine and acid vapours, when drawn through a
heater, can rapidly cause corrosion of the heat exchanger.

3. Keep the heater area free from garden refuse and debris. This will help prevent insects nesting

in the unit and ensure extended life and reliability of your heater.

4. Have your heater professionally inspected at least every 2 years.

WINTER OPERATION

If the pool won’t be used for a month or more, turn the heater off at the main gas isolation valve.
For areas where there is no danger of freezing, water should circulate through your heater all year
long even though you are not heating your pool.

Where freezing is possible, it is necessary to drain the water from the heater. This may be done by
loosening the inlet or outlet barrel union. If the heater is below water level, isolate it from the pool
first by closing shut off valves before and after the heater.

CAUTION: If the heater has been drained for freezing conditions, do not turn on until the system
is circulating water.

Viron Pool and Spa Heater Page 9

INSTALLATION

THIS APPLIANCE MUST BE INSTALLED BY AN AUTHORISED PERSON. Refer to heater
data plate for specifications of gas type, gas consumption, burner pressure and water pressure.

This appliance must be installed in accordance with local regulations and A.G.A. Installation Code
AS5601.
The installer must test the operation of the appliance before leaving.

FLOW RATES

The Viron Pool Heater requires a minimum of 150 litres per minute flow and the maximum
permissible flow rate is 500 litres per minute. For flow rates in excess of 500 litres per minute, an
external by-pass valve must be fitted.

WATER CONNECTIONS

The heater should always be installed after the pump and filter. The water connections are located
on the right hand side of the heater. The inlet and outlet are clearly marked. Water connections
require 50 mm PVC glue in plumbing.

All automatic sanitising devices must be installed after the heater and in such a way that the
sanitiser cannot enter the heater without first mixing with the water in the pool or spa. Sanitisers
that are connected prior to the heater will void heater warranty.

ELECTRICAL CONNECTION

The heater is supplied with a standard 10 amp 3 pin plug for connection to a 240V 10 amp GPO.
All pool or spa equipment connected to mains power should be protected by an RCD circuit
breaker.

GAS CONNECTION

The gas connection is on the rear of the heater. A 22mm M.I. connection is provided for gas line
connection. An approved manual shut off valve must be installed in the gas fitting line before the
heater.

The gas fitting line should be installed by an authorised person and comply with local regulations
and A.G.A. code AS5601. The gas line from the meter will usually be of a larger size than the gas
inlet connection.

The heater gas valve has a built in pressure regulator and ǩ” pressure test point. On starting the
heater, a manometer must be used and the supply inlet pressure checked while the heater is
running against the heater data plate. Incorrect inlet pressures may void warranty and may result
in service charges, should service be required. Gas valves are preset and should only be adjusted
by trained Astral Pool technicians.

PRESSURE SWITCH ADJUSTMENT

The Viron Pool Heater incorporates a water pressure switch which allows the burner to operate
only when the circulating pump is operating. The pressure switch is designed to operate with the
heater installed up to 3 metres above or below the surface level of the pool or spa.

It is imperative that the following be undertaken by the person who is commissioning (first
starting) your pool or spa heater. On initial start up of the heater it may be necessary to adjust the
water pressure activation switch.

This switch is located behind the top right hand side panel and is screwed into the water manifold.
The pressure switch is a safety device, designed to allow operation of the heater only when the
circulating pump is on and there is sufficient water flow through the heater. It must shut the heater
down immediately the pump is switched off.

To check the operation of the switch:

1. Connect the heater to mains power supply and turn power on. The thermostat should not yet

display “ș”.

2. Turn on pump. The thermostat should now display “ș”.

3. Turn pump off. The thermostat should no longer display “ș”.

4. If display does not respond in this way, adjust the pressure switch as detailed below. If display

responds correctly, perform a final check with the heater operating.- See the section below
titled “Starting the heater”

To adjust pressure switch:

1. Connect the heater to mains power supply and turn heater thermostat to “OFF”.

2. Turn pump on.

3. View display of heater to confirm the “ș” has appeared on the LCD display on front of heater.

Viron Pool and Spa Heater Page 12

4. If no symbol is present, slide toggle up to allow adjustment, then rotate knurled wheel anti

clockwise (as viewed from above) until “ș” is displayed.

5. Switch off pump.

6. View LCD display to confirm “ș”has disappeared.

7. If “ș” symbol is present when pump is OFF or “ș” does not disappear within 1 (one) second of

pump turning off, the pressure switch must be adjusted.

8. With Pump turned OFF, turn knurled wheel clockwise to increase the pressure required to

activate the switch.

9. Repeat steps 2 to 8 until symbol appears and disappears when pump turns on and off.

10. When the switch is correctly set, slide the toggle down to lock the knurled wheel in position.

11. If pressure switch cannot be made to activate heater when pump is turned on and off, a flow

switch may need to be purchased and fitted. Contact your local Astral Pool office for details.

WARNING: If the pressure switch cannot be adjusted correctly, DO NOT OPERATE THE
HEATER, contact Astral or an Authorised Service Agent for advice.

12. Perform a final check with the heater operating.- See the section below titled “Starting the

heater”.

It is imperative that the heater is installed so that it does not operate when the circulating pump
stops. Recommended methods to achieve this are:

a) Correct adjustment of internal pressure switch. Ensure heater does not turn on two or

three minutes after circulating pump is turned off.

b) Installation of an external flow switch may be preferred under certain installations

where internal pressure switch does not turn heater off when circulator stops.

TESTING INLET PRESSURE

1. Note – gas pressure must be measured when unit is operating.

2. Set thermostat to “OFF”.

3. Remove top cover (2 screws at rear of heater, remove L/H side panel, remove front 2 screws

hidden inside side panel area)

4. Remove electrical enclosure screws and hinge cover forward.

5. Loosen screw from ǩ” brass test point located on inlet side of gas valve

6. Connect manometer tube to test point

7. Set thermostat to “ON” and wait for burner to ignite

8. Once burner has ignited, the manometer must indicate the nominal inlet pressure listed below.

9. Adjust inline pressure to meet minimum required pressure at main gas regulator. Do not

adjust gas valve settings..

10. Tighten test point screw.

11. Refit covers.

CONDENSATE DRAIN

The Viron heater is a highly efficient gas appliance capable of generating 12 litres an hour of
condensation. Suitable drainage provision must be provided to ensure condensation does not build
up in the heater or flood damage surrounding areas. Do not raise the drain hose higher than the
exit point of the appliance.

Alternatively, the condensate can be used to replenish or “top up” your pool water. The Viron is
supplied with 3 metres of clear plastic tubing which connects from the condensate drain point into
a 50mm PVC “T” (Supplied) which plumbs into the front of the pump.

When the heater commences operation, a solenoid valve will open the condensate line and allow
the vacuum created by the pump to draw the condensate into the pool water.

The condensate has a pH of approximately 6.8. Most chlorines and sanitisers used for pool water
disinfection will increase the pool water pH over a period of time, so an additional advantage of
the condensate produced by your Viron Heater is that the low pH will counter balance the high pH
of the disinfectant used in most pools.

IMPORTANT: Chlorines, disinfectants and sanitisers usually require a narrow bank of pH in
which to work effectively. Ensure you check the pH of your pool or spa weekly, and adjust as
necessary.
