• Electrical Heater
• Installation and Operation Manual
6. INSTALLATION
The heaters are designed for indoor and outdoor use.
All units must be mounted on a level base parallel to the
ground. Secure the unit 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
unit, make sure you do not use glue or putty. Any glue
or putty going into the unit will damage the flow sensor
permanently. Prior to the final connections to the unit,
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.
• Spa/pool heater must be installed after installation of
the filter.
•
Spa models (ELS 0005 and 0011) are supplied with
1-1/2" NPT inlet and outlet plumbing connections.
•
Pool models (ELS 0018 and 0028) are supplied with
2" NPT inlet and outlet plumbing connections.
• All models are rated 240V single phase.
• Units 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 unit.
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 spa/pool heater and purge the
air out of the lines before allowing the unit 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 unit.
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 and maximum of 60 gpm. A manual bypass valve
is needed when the flow rate exceeds 60 gpm.
Unit will not energize elements if the water flow is under
15 gpm. Once 15 gpm 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 unit's supporting base must be high
enough to keep completely free of standing water at all
times.
