3H. Periodic Inspection
WARNING
Improper installation or maintenance can cause nausea or asphyxiation from carbon monoxide in flue gases which could result in severe injury, or death.
3H-1. Owner Inspection
Waterpik Laars designs and constructs the Laars Lite 2 heater to provide long performance life when installed and operated properly under normal condi- tions. The following basic guidelines are suggested for your inspection:
1.Keep the top and surrounding area of the heater clear of all debris.
2.Keep the heater area clean and free of all com- bustible materials, flammable liquids and vapors, as well as sanitization chemicals.
3.Do not use the heater if any part has been under water. Immediately call a qualified professional technician to inspect the heater and replace any part of the control system which has been sub- merged.
N'utilisez pas cet appareil s'il a été plongé dans l'eau, même partiellement. Faites inspecter l'appareil par un technicien qualifié et remplacez toute partie du système de contrôle et toute commande qui ont été plongés dans l'eau.
4.If the heater is equipped with a pressure relief valve, check for corrosion in and around the valve. With the filter pump on, lift the release lever on the top of the valve to make sure that water runs freely through it. If corrosion is found, replace the pressure relief valve. When replacing the valve, be sure that the pump is off. Install the valve so that the discharge is directed away from any area the may be damaged by water.
5.Be sure all combustion air and ventilation open- ings are not blocked.
3H-2. Professional Inspection
In addition, annual inspections by a qualified professional technician are recommended to keep the heater operating safely and efficiently through the years. The following basic checks should be performed.
1.Check for loose or broken wires and terminal connections.
2.Verify pressure switch operation by cycling the spa pump on and off a few times. The heater should go off immediately after the pump stops.
3.Inspect the electrical controls, specifically the following:
a.High limit controls.
b.Pressure switch.
c.Temperature control.
d.Automatic gas valve.
4.Inspect the venting system for blockage, leakage, and corrosion.
5.Check for spider webs in the pilot and main burner orifices - especially at Spring
6.Conduct a normal operating cycle and observe that the sequence proceeds as intended.
7.Inspect the external surfaces of the heat exchanger tubes for black carbon soot buildup by placing a mirror between and under the burners when the heater is firing. Remove any soot that has collected on the tubes, and correct the cause.
