LITE 2 MODEL LG POOL AND SPA HEATER
3F-3. Corrosion
The corrosive action of spa water is increased by
the following:
1. Low pH - acidity
2. Low total alkalinity - bicarbonates
3. Low calcium hardness - soft water
NOTE:
Zodiac Pool Systems, Inc., does not
warrant heat exchangers damaged by corrosive
water.
3F-4. Testing
Zodiac Pool Systems, Inc., recommends that
owners purchase a test kit and use it regularly. A
minimum kit is one which will measure chlorine, pH
level, and alkalinity.
The pool or spa owner should have a profes-
sional service technician perform more extensive
chemical testing and water changing.
3G. Swimming Pool Energy Savings Tips
Zodiac Pool Systems, Inc., offers the following
recommendations to help conserve fuel and minimize
the cost of operating your pool heater without sacrific-
ing comfort.
1. The Red Cross recommends a maximum
water temperature of 25°C. Use an accurate
pool thermometer. A difference of 4 degrees,
from 25 to 28°C will use as much as 40%
more gas.
2. Carefully monitor the water temperature of
your pool in the summer time. You can
reduce heater usage due to warmer air
temperatures.
3. Find the proper setting on the pool heater
temperature control. Use the TEMP-LOK to
discourage further adjustments.
4. Set the filter time clock to start the pump no
earlier than 6:00 AM during the pool heating
season. This is the time when nightly heat
loss balances.
5. If the pool is only going to be used on
weekends, reduce the heater thermostat
setting by 8 or 10 degrees during the week.
Reset it to the 25°C level a day or so before
you plan to use the pool.
6. During the winter, and when on holiday for
longer than a week, follow the instructions in
Section 3 to shut down the heater.
7. Where possible, shelter the pool from
prevailing winds with well-trimmed hedges or
other landscaping, cabanas, or fencing.
8. Always use a pool cover when practical.
Besides providing a valuable safety feature, a
pool cover will reduce heat loss, conserve
chemicals, and reduce the load on filter
systems.
3H. Periodic Inspection (Routine Service)
WARNING
Improper installation or maintenance can
cause nausea or asphyxiation from carbon
monoxide in flue gases which could result in
severe injury, property damage, or death.
Zodiac Pool Systems, Inc., designs and con-
structs the Lite 2 heater for a long performance life
when installed and operated properly under normal
conditions. Have regular inspections at least annually
by registered gas service personnel to keep the heater
operating efficiently. The service technician should
check the following:
1. Keep the top of the heater clear of all debris.
Make sure there is no collection of flammable
materials, leaves, paper, etc., around or under
the heater.
2. Keep the pool heater area clean and free of
all combustible materials, gasoline and other
liquids, and vapors.
3. Do not use the heater if any part has been
under water. Immediately call a qualified
service technician to inspect the heater and to
replace any part of the control system and
any gas control which has been under water.
4. Check for spider webs in the pilot and main
burner orifices — especially at Spring start
up.
5. Make a regular visual check of the main
burner and pilot flame patterns
(see Figure 22).
