INSTALLATION

Pump Location

Pump Location
• Install the pump in a clean, dry, and ventilated location shielded from direct sun and precipitation.
• Provide adequate room for future servicing, protection from freezing temperatures, flooding, and
equipment drainage.
• Bolt unit down evenly on a good foundation, preferably concrete, to prevent unnecessary stresses
from pump movement.
• Install as close as possible to water source to minimize suction piping length.
• Keep motor-operating area as dry as possible.

Physical Installation

Risk of bodily injury, property damage, or damage to system by pressurized
fluids.
DO NOT install this product if incoming water pressure is greater than 75 psi. Serious damage to plumbing can occur.
•
• A pressure relief valve rated to handle full pump flow at 75 psi should be installed in the system to prevent personal injury or
property damage.
• Do not use this pump for pumping sea water, beverages, acids, chemical solutions, or any other liquid that promotes corrosion as
this can result in damage to the pump.
Risk of damage to pump or other equipment.
• Do not apply power to the system until the pump is primed. Do not run the pump dry, which can cause overheating and damage
the impeller and seals. This will void the warranty.
• Do not use open-style wrenches to loosen plugs. Plugs may become damaged and difficult to remove.
• Red Lion is not responsible for personal injury or property damage due to improper installation.
1. Turn off the main water supply and the power at the main breaker.
2. Open a nearby faucet to release the water pressure in the system. Once all water and pressure is
released, turn off the faucet.
3. Modify the existing plumbing as required to allow for installation of the pump system.
IMPORTANT: A check valve should never be installed between the pump and the tank.
• The pump suction is 1 inch FNPT and the discharge is 1 inch FNPT fittings. Depending on the size
of your piping, adapters may need to be installed.
• Seal and tighten the threads of the suction and discharge openings on the pump with PTFE tape
or thread compound. Do not over-tighten the connections as this could crack the fittings.
• Make sure all joints are airtight as even a pinhole can prevent proper operation of the pump.
• Refer to "Typical Installations" on page 3
IMPORTANT: Ensure any burrs or shavings from cutting the pipes are completely removed to pre-
vent damage to the pump.
4. Install a pressure relief valve near the discharge rated to handle pump flow at 75 psi.
5. Install a pressure gauge into the 1/8" NPT hole on the front of the casing, opposite the pressure
switch. Refer to
6. For systems with a tank, make sure the pre-charge pressure of the tank is 28 psi, as this pump's pre-
charge pressure (or the pressure at which the pump will start) is 30 psi.
• If a perma-pressure tank is not used, an air volume control should be used to maintain an air
cushion in the pressure tank. Refer to the pressure tank owner's manual.
7. Add unions and valves to allow system service without disabling the complete water supply.
