PLEASE READ THE FOLLOWING INSTRUCTIONS CAREFULLY
IMPORTANT GENERAL SAFETY INFORMATION -
ADDITIONAL SPECIFIC SAFETY ALERTS APPEAR IN THE FOLLOWING INSTRUCTIONS.
If the control is set too high or the pump is running when the water supply is shut off and there is no demand on the system, the pump will run continuously, can overheat and become damaged, potentially resulting in product failure, leaking and/or rupture.
All wire and fuse sizings are preliminary recommendations only. For your safety, local codes, and in their absence, national codes must be followed to minimize the risk of electric shock, property damage or personal injury.
The pump motor is designed for use with single phase, 60Hz ac. Use with any other type of power will cause damage to the motor. The pump models
The power for your pump must be on a dedicated circuit. In addition, a shut off switch should be visible and near the pump. Use a 20 amp circuit.
Before attempting any service and disassembly, shut off power to the pump. Ensure power is disconnected prior to removing motor. Ensure power is disconnected
before cleaning is attempted.
Grounding of the pump is essential for your protection and the protection of the motor. All wiring should be completed by a licensed electrician, and in accordance with
local codes or in their absence, the National Electrical Code. Before starting the wiring installation, disconnect all power to the circuit to be used for the AMTROL Pressuriser®.
The AMTROL Pressuriser® should only be connected to a municipal, cold water supply, and in systems with a minimum pressure of 10 psig at all times, measured under flow at the tap closest to the location of the AMTROL Pressuriser® installation.

Metal piping must be used for all inlet and outlet lines to the unit.
Do not oversize pump. Inadequate water supply will result in poor performance and pump damages.
Pre-Installation
•DO NOT USE FOR
•DO NOT USE FOR ANYTHING EXCEPT COLD WATER (AMBIENT TEMPERATURE NOT TO EXCEED 100° F);
•DO NOT USE IN SYSTEMS WHERE LOW PRESSURE IS
DUE TO LEAKS OR WHERE LEAKS IN THE PLUMBING
SYSTEM MAY EXIST;
•DO NOT USE IN SYSTEMS WHERE THE WATER SUPPLY CAN DROP BELOW 10 PSIG;
•DO NOT USE IN SERIES WITH ANOTHER PUMP (SUCH AS IN PRIVATE WELL WATER SYSTEMS);
•DO NOT
•DO NOT PIPE EXCEPT WITH METAL PIPING AT INLET
AND OUTLETS.
The system must be placed indoors only on a solid level surface with a drip pan piped to a drain with adequate capacity for large volumes of water in the event the system ruptures or fails. Consider the risks posed by tanks under pressure and the potential for leaking and/or flooding damage in selecting the location. The unit must not be placed in an environment that would expose the water in the tank to temperatures below freezing or in
excess of 100° F. | Figure 1 |
