INSTALLATION, OPERATING AND SERVICE MANUAL
CITY BOSS™
RESIDENTIAL CITY WATER PRESSURE BOOSTER SYSTEM
CITY BOSS™ is a city water pressure booster system utilizing the MASCONTROL® pump
controller and a single stage pressure booster pump. The pump controller monitors both
flow and pressure, controlling the operation of the pump automatically. The system maintains
constant boosted water pressure during operation. No pressure tank or switch required. No
adjustment or maintenance is needed.
CAREFULLY READ THE LITERATURE PROVIDED BEFORE INSTALLATION!
Familiarize yourself with the specific details regarding installation and use.
Leave this manual with the system for future reference.
LANCASTER PUMP RECOMMENDS A QUALIFIED PROFESSIONAL TO INSTALL THIS SYSTEM.
INSPECT THE SYSTEM COMPONENTS:
Occasionally, products are damaged during shipment. If a component is damaged, contact the transportation company
or your dealer. Save the product’s packing materials until the claim is settled. The system package includes pump, pump
controller, and rubber grommets. For systems utilizing 1¼ MNPT pump controller, pipe fittings are included to connect
pump to pump controller.
SAFETY INSTRUCTIONS
1.
WARNING – HIGH PRESSURE. The pump can boost to high pressure. Verify the incoming water pressure
BEFORE installing the booster system. Make sure the incoming water pressure plus the pressure boost
developed by the pump is a SAFE psi for the application’s piping and fixtures. If required, a pressure
reducing valve can be installed in line after the booster system to reduce water pressure to a safe level. A
pressure relief valve piped to a suitable drain is recommended for overall system protection. Never install or
service the pump or system without relieving the internal pressure.
2. WARNING – HAZARDOUS VOLTAGE. Voltage can shock, burn or cause death. Install, ground and wire pump
and controller according to local and national electrical code requirements that apply. The pump’s single
phase motor is equipped with automatic resetting thermal protection. The motor may re-start unexpectedly
causing the leads to energize or pump to turn. DISCONNECT ELECTRICAL POWER SUPPLY BEFORE
INSTALLING OR SERVICING THE PUMP. Capacitor voltage may be hazardous. To discharge motor capacitor,
hold insulated handle screwdriver (BY THE HANDLE) and short the capacitor terminals together. Do not touch
metal screwdriver blade or capacitor terminals.
3. Install the water pressure booster system according to all plumbing code requirements.
4.
Pump only water with this system. Pump can be severely damaged if run dry. The pump controller will
detect a run-dry condition and shut off the pump. Do not pump water above 120° F, due to internal pump
components temperature limitations. Do not allow pump, pump controller, piping or any other system
component to freeze. Freezing may damage system, leading to injury or flood.
5.
Pipe joint compound can cause cracking in plastics. Use only Teflon tape when sealing threaded plastic pipe
or connecting pipe to plastic components such as the pump controller.
