• Electrical Heater
• Installation and Operation Manual
6. INSTALLATION
The heaters are designed for indoor and outdoor use.
• 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 least
24" (610 mm) away from the heater.
Recommended Clearances:
TOP:
18" (457 mm)
SIDES
: 6" (152 mm) away from your heater and the
outlet hot water pipe.
7. WATER CONNECTION
Please follow all plumbing instructions carefully. This
product must be installed by a licensed and qualified
plumber in accordance with all applicable national, state,
pro vincial, and local plumbing codes.
IMPOR
TANT: 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 flow sensor
permanently. Prior to the final connections to the heater,
flush all the lines to clear any debris.
NOTE:
When using two-speed pumps, do not install a gate
valve on the inlet. No shut-off 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.
• The heater must be installed after installation of the
filter.
• 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 flow activated.
• No Hartford loop is required.
After tightening both fittings 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 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 off to the heater and purge the air out of
the lines before allowing the heater to power up.
Dry-Firing of Elements
Dry-firing 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 filter. The filter 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 flow of water for proper
operation. Adequate water flow removes the heat produced
by the heater and transfers the heat to the spa/pool and
prevents overheating. Low water flow usually results
from dirty filter or improperly adjusted manual bypass.
The heater is designed to run at a minimum flow rate of
15 gpm (57 lpm) and maximum of 60 gpm (227 lpm). A
manual bypass valve is needed when the flow rate exceeds
60 gpm (227 lpm). The heater will not energize elements
if the water flow is under 15 gpm (57 lpm). Once 15 gpm
(57 lpm) has been established, the heating elements will
energize 1 minute after flow is configured. This is to make
sure the tank is completely filled with water and any air in
the tank has had time to escape.
CAUTION:
The heater's supporting base must be high
enough to keep completely free of standing water at all
times.
RAIN WATER RUN OFFS. The heater is designed to operate
outdoors and can be exposed to rain. However, rain water
run-off falling directly onto the heater from a roof can
cause damage and/or shorten the life of your heater.
This may also void your warranty. Install rain gutters or
rain diverters on your roof if the heater is installed in a
position where contact with rain run-off may occur.
