CAUTION: Corrosive water voids all warranties
A
a temperature of 78°F (26°C) for competitive swimming.
However, this may be too cool for young children and the
elderly, who may require a te mperature of 80°F (27°C) or
higher.
For your health and the protection of your pool equipment,
it is essential that your water be chemically balanced. The
levels shown in Table A must be used as a guide for
balanced water.
Pool/Spa Water Chemistry
Occasional chemical shock dosing of the pool or spa
should not damage the heat exchanger providing the water
is balanced. Automatic chemical dosing devices and salt
chlorinators are usually more ecient in heated water. If
not controlled, they can lead to high chemical levels which
can damage the heat exchanger. Further advice should
be obtained from your pool or spa builder, accredited pool
shop, or chemical supplier for the correct levels for your
water.
Water Chemistry Allowable Levels
Water Temperature 68-104°F (20-40°C)
pH 7.6-7.8
Total Alkalinity (ppm) 80-120
Calcium Hardness (ppm) 200-400
Salt (ppm) 4500 Maximum
Free Chlorine (ppm)* 2-3
Total Dissolved Solids (ppm) 3000 Maximum**
*Free Chlorine MUST NOT EXCEED 5 ppm!
**In saltwater chlorinated pools, the total TDS can be as high as 6000
ppm.
Table A. Spa and Pool Water Chemistry
Automatic Chlorinators and Chemical
Feeders
All chemicals must be introduced downstream of the
heater and completely diluted into the water before being
circulated through the heater. Chlorinators must feed
downstream of the heat exchanger and have an antisiphoning device or check valve to prevent chemical backup into the heat exchanger when the pool ltration pump
is shut o.
CAUTION: High chemical concentrations from
A
feeders that are out of adjustment will cause rapid
corrosion of the heat exchanger. Such damage is not
covered under the warranty.
CAUTION: Failure of a heat exchanger due to lime
A
scale build-up on the heating surface, low pH, or other
chemical imbalance is not covered under the warranty.
3. SAFETY INFORMATION
Pool water temperatures typically range from 78°F (26°C)
to 82°F (28°C). The American Red Cross recommends

IMPORTANT SAFETY INSTRUCTIONS
READ AND FOLLOW ALL INSTRUCTIONS
GIVEN IN THIS MANUAL.
The water in a spa or pool should never exceed 104°F
(40°C). A water temperature in excess of 104°F (40°C)
is considered unsafe for all persons. Lower water
temperatures are recommended for extended use
(exceeding 10-15 minutes) and for young children.
Excessive water temperatures have a high potential
for causing fetal damage during the early months of
pregnancy. Pregnant or possibly pregnant women
should limit spa or pool water temperatures to 100°F
(38°C).
Before entering a spa or pool, the user should measure
the water temperature at several locations using an
accurate thermometer since the tolerance of water
temperature - regulating devices may vary as much as
much as +/- 5°F (3°C)
Alcohol, drugs or medication should not be used before
or during spa or pool use since their use may lead to
unconsciousness with the possibility of drowning.
Persons suering from obesity or with a medical history
of heart disease, low or high blood pressure, circulatory
system problems, or diabetes should consult a physician
before using a spa or pool.
Persons using medication should consult a physician
before using a spa or pool since some medication may
induce drowsiness while other medication may aect
heart rate, blood pressure and circulation.
Prolonged immersion in hot water may induce
hypothermia. Hypothermia occurs when the internal
temperature of the body reaches a level several degrees
above normal body temperature of 98.6°F (37°C).
The symptoms include dizziness, fainting, drowsiness,
lethargy and an increase in the internal temperature of the
body. The eects of hypothermia include: Unawareness
of impending hazard, failure to perceive heat, failure to
recognize the need to exit spa or pool, physical inability
to exit spa or pool, fetal damage in pregnant women and
unconsciousness resulting in a danger of drowning.

5. BEFORE INSTALLATION
Please read these instructions thoroughly and completely
before installation and before use. Failure to do so could
cause property damage or serious personal injury or death
and void your warranty.
By installing this product, you acknowledge the terms of
the manufacturer's warranty and your Authorized Dealer's
return policies. The heaters that have been installed
cannot be returned. If you have any questions regarding
the warranty or product return policies, please consult your
Author ized Dealer prior to installation.
Open the box and carefully unpack the heater. Inspect all
components.
6. INSTALLATION
The heaters are designed for indoor or outdoor use. The
heater should be mounted on a level, non-combustible
surface. Heater must not be installed on carpeting. Do
NOT use the shipping crate base as an installation base.
• The heater must be mounted on a vertical position
over a ground level base or a wall.
• Secure the heater to the base with screws (not
provided).
CAUTION: Combustible materials should be kept at
A
least 24" (610 mm) away from the heater.
Recommended Clearances:
• TOP: 18" (45.7 cm)
• SIDES: 6" (15.2 cm) away from your heater and the
outlet hot water pipe.
7. WATER CONNECTION
IMPORTANT: When preparing the connections going
to heater, make sure you do not use glue or putty. Any
glue or putty going into the heater will damage the ow
sensor permanently. Prior to the nal connections to the
heater, ush all the lines to clear any debris.
NOTE: When using two-speed pumps, do not install
a gate valve on the inlet. No shuto valves are to be
installed in the piping between the spa heater outlet and
the spa. If using an in -line chlorinator, a check valve
must be used. Any chlorinator valves that can cause
return line block age will VOID the warranty.
Please follow all plumbing instructions carefully. This
product must be installed by a licensed and qualied
plumber in accordance with all applicable national, state,
pro vincial, and local plumbing codes.
• The heater must be installed after installation of the
lter.
• Models ELS 0005 and 0011 are supplied with
1-1/2" NPT inlet and outlet plumbing connections.
• Models ELS 0018 and 0027 are supplied with
2" NPT inlet and outlet plumbing connections.
• All heater models are rated operation ONLY on 240V
single-phase, 60Hz power.
• Heaters are ow activated.
• No Hartford loop is required.
After tightening both ttings at the water heater, start the
pump to allow water to run through the spa/pool heater for
at least 5-10 minutes. This process purges all the air from
the water lines and must be performed prior to turning on
the power at the heater.
CAUTION: Failure to follow this step can cause
A
permanent damage to the heating elements.
When any maintenance is performed on the spa/pool that
may introduce air into the plumbing pipes, it is important to
turn the power o to the heater and purge the air out of the
lines before allowing the heater to power up.
Dry-Firing of Elements
Dry-ring of elements is caused by water voids when power
is on. All air must be purged from the system before any
heat start-up. It is important to purge all air after cleaning
or changing a car tridge lter. The lter casing acts as an
air reservoir during this procedure, the circulation system
must be on for at least two (2) minutes before you turn
power on to this heater.
The heater must have an adequate ow of water for proper
operation. Adequate water ow removes the heat produced
by the heater and transfers the heat to the spa/pool and
prevents overheating. Low water ow usually results
from dirty lter or improperly adjusted manual bypass.
The heater is designed to run at a minimum ow rate of
15 gpm (57 lpm) and maximum of 60 gpm (227 lpm). A
manual bypass valve is needed when the ow rate exceeds
60 gpm (227 lpm). The heater will not energize elements
if the water ow is under 15 gpm (57 lpm). Once 15 gpm
(57 lpm) has been established, the heating elements will
energize 1-minute after ow is congured. This is to make
sure the tank is completely lled with water and any air in
the tank has had time to escape.
RAIN WATER RUNOFF. The heater is designed to
operate outdoors and can be exposed to rain. However,
rain water runo falling directly onto the heater from a
roof can cause damage and/or shorten the life of your
heater. Such damage will not be covered under warranty.
Install rain gutters or rain diverters on your roof if the
heater is installed in a position where contact with rain
runo may occur.
CAUTION: The heater's supporting base must be
A
high enough to keep completely free of standing water
at all times.
