1) The system is a low 24 Volts, but it should be serviced only with the power off. Accidental shorts may damage components.
2) Never apply direct line voltage to the valve or to the timer. Damage caused by overloads are not covered under warranty. The most common failure of timers to date has been due to the application of 110 Volts to the timer, or a surge caused by lightening. Protect all circuits as prescribed by local code.
3) Protect wires and valve from damage. Wiring should be in conduit, or run inside walls to prevent accidental or deliberate damage. Low voltage connections must be clean to work properly. If there seems to be intermittent action, check all wiring connections, and the terminals. Make sure all terminals are crimped securely, with good electrical connection. As operation is in a high humidity environment, after all connections have been made, it may be wise to coat all terminals with a clear silicone after installation to retard corrosion.
4) Always test the system before closing in any walls. It is best to provide some access to the valve should it require service.
5) The meter housing is heavy! Make sure it is mounted securely to studs or into concrete walls with molybolts. Do NOT use butterfly anchors in drywall, greenboard, or cementboard walls.
6) The screen may need occasional cleaning. Like other plumbing, the valve needs to be protected from freezing. Removing the mixing valve cores in the off season, so the system may drain, is a wise idea. Provide access for maintenance purposes. If the valve seems to work backward and does not shut off, make certain
7) Test the system under power, and at full water pressure before closing in any walls. Be sure to provide access to the valve for maintenance purposes.
8) Again, make sure the cam lever is turned toward the coin chute when installing and locking the service door.
9) MOST IMPORTANT. MONARCH HAS TRIED TO PROVIDE THE HIGHEST QUALITY COMPONENTS, INCLUDING UL / CSA APPROVED ELECTRICAL COMPONENTS.
MONARCH CANNOT BE RESPONSIBLE FOR AN INADEQUATE OR LESS THAN SAFE INSTALLATION. KNOW YOUR INSTALLER, AND BE CERTAIN THE INSTALLATION HAS BEEN COMPLETED PROPERLY.
