Lippert Components Flow Max Pump DS-01233-D Installation

The following guidelines should be considered to achieve optimum pump performance. Mount the pump with four screws. In many instances, the pump is being utilized as a replacement pump. Adjust instructions as needed.
NOTE: The mounting feet are intended to isolate the pump from the mounting surface. Overtightening, flattening or the use of oversize screws will reduce the ability to isolate vibration and noise through the lines.

NOTE: Always follow all local or national installation codes and standards.

General Installation Instructions

Solid surface should be available for mounting to prevent vibration and noise.
Accessible location away from living quarters.
Properly-sized wiring.
Proper electrical protection.
Flexible hose on inlet and outlet.
Strainer on plumbing elbows and valves near the pump.
Minimize flow restrictions in the system.

Mounting Instructions

The pump may be located at the same level or below the water tank. However, if necessary, the pump may be positioned above the water tank since it is capable of a 6 ft. vertical prime. Also, horizontal inlet tubing will allow priming to 30 ft.
Consider a dry location that allows easy access, if maintenance is required.
Installation space for the pump should be at least 1 cubic foot to allow for adequate ventilation and prevent overheating.
NOTE: Excessive heat may trigger the integral thermal breaker and interrupt operation. When the temperature drops, the breaker will automatically reset.
The pump may be mounted in any position. However, if pump is mounted vertically, the pump head should be in the down position to avoid leakage into the motor casing during a malfunction.

Plumbing The System

Install in-line screen (Fig. 1A) on the inlet port of the pump (Fig. 1B) to prevent debris from entering the pump.
Using the supplied 1/2" swivel connectors (Fig. 1C), connect flexible, high-pressure hoses to both the outlet port of the pump and the inlet port of the in-line screen (Fig. 1).
Note: The pump ports and strainer should not be connected to plastic or rigid pipe. At least 1' of flexible, high-pressure tubing is recommended. The pump's normal oscillation may be transmitted through rigid plumbing, causing noise and possibly loosening or cracking components.
Plumb the system with flexible pipe/tubing that is a minimum of 1/2" inner diameter reinforced hose for main lines.
Note: Hex/swivel barb fittings provide easy removal if maintenance or access is required. The fittings are designed with a "taper seal" to create a watertight connection when hand tightened. Always secure barb tubing connections with properly-sized stainless steel clamps to prevent leaks.
Note: Never use thread sealing tape or sealing compounds on threads. Tape or sealing compounds may enter the pumps and cause a failure.

Rapid cycling may be caused by excessive back pressure created by one or more of the following within the plumbing system:

Water filters and purifiers not on separate feed lines;
Flow restrictors in faucets and shower heads;
Small inner diameter lines;
Restrictive fittings and connections, e.g. elbows, Ts and feeder lines to faucets.

To reduce rapid cycling, the pump shutoff pressure switch setting (Fig. 2) can be increased by turning the screw clockwise 1 1/2 turns maximum.

Electrical Connections

CAUTION: Proper wire sizing is required for good pump operation. If the wire is too small, low voltage will affect the pump performance and can create a fire hazard.

NOTE: The pump should be on a dedicated circuit protected by the specified fuse as indicated on the motor label.
The chart lists the minimum wire size for a 10% voltage drop on a 12V DC 10 amp circuit. Length is the distance in feet from the power source to the pump and back to ground.

Determine the proper wire size for good pump operation.

Install a 15 amp switch (ignition protected) on the positive lead (red wire) (Fig. 1). The switch should be mounted in an easily accessible location.
NOTE: For marine use, a 15 amp marine duty (ignition protected) switch is required.
Connect the positive lead (red) to the switch.
A second positive lead wire of the same size should be connected to the battery from the switch.
NOTE: A 10 amp fuse is required as per applicable codes.
Connect the negative ground wire (black) to the negative (black) terminal of the battery.
NOTE: The ground, positive and switch wires must all be of the same gauge.
NOTE: Shut off power to the pump when leaving the unit unattended.

Sanitizing

Potable water systems require maintenance to keep components working properly to deliver a consistent flow of fresh water. Sanitizing is recommended prior to storing. After a period of time in storage or any time the system is opened or contaminated, sanitizing is also recommended. Systems with new components or ones that have been subjected to contamination should also be disinfected.

Determine the amount of common household bleach needed to sanitize the tank.
1. Multiply the gallons of tank capacity by 0.13. The result is the number of ounces of bleach needed to sanitize the tank.
Mix the bleach with water in a container.
Pour the bleach solution into the tank and fill the tank with potable water.
Open all faucets (hot and cold) and allow water to run until the odor of chlorine is detected. Then shut off the faucets.
Allow 4 hours contact time to disinfect the tank.
At the conclusion of the prescribed contact time, drain the tank.
Refill the tank with clean, potable water and flush the system once or twice until the chlorine odor has decreased. The residual chlorine odor and taste is not harmful.

Winterizing

If water is allowed to freeze in the system, damage to the plumbing and pump may occur. To protect against damage from freezing, completely drain the tank, pump and plumbing and perform winterizing tasks.
NOTE: When used per the RVIA recommendations, non-toxic antifreeze for potable water is safe for use in the pump.

WARNING
Do not use automotive antifreeze to winterize potable water systems. Such solutions are highly toxic. Ingestion may cause serious injury or death.

Drain the water tank.
NOTE: If the tank doesn't have a drain valve, open all faucets while allowing the pump to operate (15 minutes on/15 minutes off) until the tank is empty.
Open all the faucets, including the lowest valve or drain in the plumbing, and allow the pump to purge the water from the plumbing. Then turn off the pump.
Using a pan to catch the remaining water, remove the hoses at the pump's inlet and outlet ports.
Turn the pump on, allowing it to operate until the water is expelled.
Once the plumbing is emptied of water, turn off power to the pump. Do not reconnect the hoses to the pump.
Make a note at the water tank's filler cap as a reminder: “Plumbing is disconnected. Do not fill.”
Leave all faucets open to guard against damage.
NOTE: Sanitize the plumbing system before putting it back into service. See Sanitizing section.
