AquaLink
Installation Guidelines (also includes propane heaters)
General Heater Wiring Guidelines:
Electric Heaters and Heat Pumps
This instruction sheet is for low voltage heaters. Do not attempt to
connect a heater with a high voltage (110 or 220 VAC) thermostat
into the low voltage heater terminal bar.
Natural Gas Heaters and Propane Heaters
1. Connect two 18 gauge wires, designed for use in hot environments,
to the proper terminals on the Heater Terminal Bar.
2. Bring two heater wires from the AquaLink RS P.C. Board over to
the heater and wire in series with the heater circuitry as if you
were wiring a fireman's switch or heater delay.
3. Do not disconnect high limit or pressure switches.
4. Turn the heater thermostat(s) to maximum setting.
5. Turn the heater toggle switch to ON.
Guidelines for All Laars Heaters
(except Laars LX):
1. Remove the heater service door.
2. Remove the factory-installed wire between Terminal 1
and Terminal 2 on terminal strip (see diagram at right).
3. Connect the wires from the AquaLink RS P.C. Board
to the two terminals. Teledyne Laars requires heater
hookup wires to be AWG 14-gauge copper with a
temperature rating of 105°F or higher.
4. Set the thermostat selector switch to ON, HIGH or
SPA and set the heater thermostat(s) to maximum.
Guidelines for Laars LX Heaters
1. Remove the LX GUI from the heater.
2. Run 4conductor cabel (red, black, yellow green) from
the LX GUI red 4 pin terminal bar to the RS Power
Center red 4 pin terminal bar.
3. If connectingmore than 2 items to the RS Power Center
red 4 pin terminal bar, a multiplex PCB is required.
