PRE-INSTALLATION PREPARATION
MAKE SURE YOU HAVE READ THE SAFETY INSTRUCTIONS PRECEEDING THIS SECTION!
LOCATION-
The water pressure booster system (pump and pump controller) should be installed in any convenient
location that provides sufficient space for installation and servicing. A clean, dry basement or utility room to avoid
dampness and temperature extremes are excellent choices when allowed by law. Check with state and local agencies to
determine restrictions in your area. A pressure relief valve piped to a suitable drain is recommended for overall system
protection.
PIPE CONNECTIONS-
Always follow state and local plumbing codes. Lancaster Pump does not sell or specify pipe types
or materials, consult with your pipe supplier to determine the best pipe for your installation. Use Teflon tape on male
threads of plastic pipe. Do not use pipe joint compound on plastic piping because it will damage piping (crack) over time.
Use minimum ¾” pipe size to the pump inlet. Provide a drain cock at a low point in the service line for draining the system.
If the booster system is inactive for any length of time, it is advisable to completely drain the system to prevent freezing.
Drain all piping to a point below the freeze line. Remember the pump controller has an internal check valve and will not
drain through. Lancaster Pump recommends installing unions or slip couplings on the inlet side of pump and discharge
side of pump controller for ease of disconnecting booster system for service or to protect from freezing.
ELECTRICAL CONNECTIONS- Wiring to this booster system must be installed and maintained in accordance with
both the National Electrical Code and state /local codes.
Make sure motor voltage rating matches available power supply. See the motor nameplate. Dual voltage motors have a
label on them that identifies the factory pre-wired voltage. If needed, the motor voltage is changed inside the motor cover.
See the motor nameplate for instruction. Make sure the breaker or disconnect is OFF before entering the motor cover.

Properly sized copper wire from service to pump controller will avoid over-heating wire and excessive voltage drop at the
motor. Pump controller should be connected to a separate branch circuit with no other appliances on it. Consult dealer or
electrician.
