Legacy™ Model LRZM Pool/Spa Heater
|
Installation and Operation Manual
The equipment and/or appliances associated
with the pool water circulating system, including, but
not limited to, pump motors and heaters must also be
bonded together as part of the equipotential bonding
grid. Zodiac provides a special labeled earth bonding
lug on the right side of the heater to accommodate this
requirement. Consult your local applicable installation
codes/regulations for additional requirements that may
apply.
If you install a time clock to control the lter
pump operation, it is recommended that the time clock
have its own low voltage (Fireman’s) switch to turn
off the heater before turning off the pump. The switch
should shut off the heater about 15 minutes before
the lter pump shuts off. This will allow for a more
efcient operation by removing any residual heat
contained in the heat exchanger back to the pool.
To install a time clock auxiliary switch into the
heater wires (see Figure 16):
1. Remove heater door.
2. Remove the factory installed wire between termi-
nals 1 and 2 on the terminal strip (see Figure 16).
3. Connect the wires from the time clock auxiliary
switch to the two (2) terminals. Use 14 AWG (2,5
mm
2
) stranded copper wire with a temperature
rating of 105°C (221°F) or greater.
The length of the wire between the heater and
the time clock should not exceed 4.57 m. The contact
points of the time clock switch should be silver, or a
low resistance alloy.
