Disclaimer: These instructions are guidelines only and in no way meant to be definitive. During installation, standard safety
precautions and equipment should be used where appropriate. Because the tools used and the skill/experience of
the installer can vary widely, it is impossible to anticipate all conditions under which this installation is made, or to
provide cautions for all possible hazards. Proper installation is the responsibility of the purchaser. All bolts,
setscrews, and belts must be checked prior to start-up AND after the initial operation. Damages due to poor
installation are the responsibility of the installer.
Waterous reserves the right to make modifications to the system without notice

SECTION 1. SAFETY, Everyone’s Concern
Please read all of the following safety precautions and follow carefully. They are important to
the prevention of personal injury or damage to the equipment.
1. Do not pump at pressures higher than the maximum recommended pressure. [400 psi
(28 BAR)]
2. Do not permanently remove or alter any guarding devices or attempt to operate the
system when these guards are temporarily removed.
3. Always disconnect the power source before attempting to service any part of the pump.
4. Release all pressure within the system before servicing any of its components.
5. Drain all concentrate and water from the discharge system before servicing any of its
component parts.
6. Check all hoses for weak or worn conditions on a regular basis. Ensure that all
connections and fittings are tight and secure.
7. Use only pipe, hose, and fittings from the foam pump outlet to the injector fitting, which
are rated at or above the maximum pressure [400 psi (28 BAR) minimum] rating at which
the water pump system operates.
8. Any electrical system has the potential to cause sparks during service. Take care to
eliminate explosive or hazardous environments during service/repair.
Caution:
Do not attempt to operate the system at or above a temperature of 160°F (71°C)
Ensure that the electrical source of power for the unit is the appropriate 12 or 24
volt, negative ground DC system, with a minimum current rating of at least 60
amps for 12 VDC or 30 amps for 24 VDC System.
Periodically inspect the pump and the system components. Perform routine
preventive maintenance as required. Failure to perform routine maintenance may
cause damage to the pump.
Read and understand ―Operation‖ section before attempting to operate the unit.
Always disconnect the ground straps and control cables from the control module or
other Aquis equipment before electric arc welding at any point on the apparatus.
Failure to do so will result in a power surge through the unit that could cause
irreparable damage to the system components.
The cables shipped with each Aquis unit are tested at the factory. Improper
handling and forcing connections can damage these cables which could result in
other system damage.

This document explains how to set up and operate the Aquis Foam Control system.
SECTION 2. INSTALLATION PLANNING
The Waterous recommends that you spend time planning where and how you intend to install this
unit in the equipment before beginning the actual installation.
Determine the locations of the components to be installed such as; foam tank, Motor / Pump
Assembly, Manifold and OIT.
Locate the pump as close to the supply source as possible. Install it in a clean space
where it will be easy to inspect and maintain. Allow room for checking the oil level,
changing the oil, and general servicing.
•Try to place components in locations that require the least amount of cables, hoses and
fittings.
•Position the Motor / Pump Assembly in an area that is protected from road debris and
excessive heat buildup.
•It is recommended that the Motor / Pump Assembly be installed in an accessible
compartment located in the vicinity of the Operator Interface Terminal (OIT) panel.
•Place the foam tank so that the refilling can be done safely.
•Most water tank manufacturers will build the foam tank into the booster tank.
•When specifying a integral foam tank, make sure provisions are made for installation of
the optional low tank level sensor as well as foam suction connections and tank drainage
according to NFPA.
Determine a location for the Operator Interface Terminal (OIT) on the operator panel of the
equipment. Refer to Fig 8 for cutout.
•Consider the routing path of the cable from the Operator Interface Terminal (OIT) to the
Pump / Motor Driver Assembly.
•If necessary, order extension cables to suit the location demands.
Warning:
Never attempt to cut or lengthen the molded cables. Cables can be daisy chained to obtain
longer lengths.
Always disconnect the ground straps and control cables from the Operator Interface
Terminal (OIT) or other Aquis equipment ―before”electric arc welding at any point on the
apparatus. Failure to do so could result in a power surge through the unit that could cause
irreparable damage to the electronic components.

Cautions:
Ensure Adequate Concentrate Supply.
Aquis 2.5 - a minimum of ¾ inch ID tubing
Safety Guards.
Follow all codes and regulations regarding installation and operation of the
Aquis system.
Shut-Off Valves.
Never install shut-off valves between the pump and discharge pressure
regulator, or in the regulator bypass line.

SECTION 3. PLUMBING COMPONENTS
A. Motor / Pump Assembly
The Motor / Pump Assembly must be mounted horizontally. The base must be anchored to a
surface or structure that is rigid and of adequate strength to withstand the vibration and
stresses of apparatus operation.
Flexible hose is required to make the hose connections from the Motor / Pump Assembly to
the foam tank.
DO NOT hard pipe the system.
Consider access requirements for checking the foam pump. Be sure the foam concentrate
hoses can be properly routed to the inlets and outlets on the foam pump.
Foam concentrates should gravity feed to the foam pump inlet from the foam tank. However
the systems are capable of drafting up to 1 meter vertically. The Motor / Pump Assembly
must be mounted in an area to avoid excessive exhaust system heat buildup.
Protect the hoses and wiring to prevent chafing and abrasion during operation of the foam
system.
Protect the Motor / Pump Assembly from excessive road spray and debris. Although the
system is sealed and designed to be resistant to the harsh environment of fire fighting
apparatus, a protected compartment with easy operator access is the recommended
installation location.

The large circuit breaker (Figure 2) is used to connect the 12 VDC input power.
Make sure you provide adequate electrical power (60 amps minimum for 12 VDC or
30 amps for 24 VDC) from the battery. Use 8 AWG (minimum) wire directly to the
battery or battery switch. Long wire runs may require 6 or 4 AWG wire for proper
operation.
Recommended wire sizes

I. Power Supply
Electrical devices can be easily damaged by a weak or erratic power supply. The
better the power supply, the better the Aquis system will perform. At maximum
output, the Aquis system can draw 60 amps at 12 VDC or 30 amps at 24 VDC.
Connect the ground lead from the chassis frame or the negative battery terminal. Use
the same size wire as the power lead.
DO NOT connect the main power leads to small leads that are supplying some other
device such as a light bar or siren.
CAUTION:
Be careful not to damage or short circuit the wires leading to the circuit
breaker. Only the Aquis system is protected by the circuit breaker.

III. Pump Maintenance
Daily
Check the oil level and the condition of the oil. The oil level should be 3/4 in. (20 mm)
from the top of the fill port.
Use the appropriate pump oil or equivalent, motor oil for the application (SAE
10W/30).

Periodically
Change the oil after the first 50 hours of operation, and every 500 operating hours
thereafter. When changing, remove the drain plug at the bottom of the pump so all oil
and accumulated sediment will drain out.
Check the inlet pressure or vacuum periodically with a gauge.
Caution:
DO NOT turn the drive shaft while the oil reservoir is empty.
Protect the pump from freezing.
B. Wye Strainer
The line strainer provided with the unit has 3/4 inch NPT female threaded ports will need to
be installed, in-line, between the foam supply tank and the foam pump. The hose from the
foam tank should have adequate wall stiffness to withstand the vacuum of the foam pump
while it is operating.
NOTE: If a pressurized water flush from one of the discharges is incorporated, the plumbing
and line strainer exposed to this pressure must be rated at or above the operating
pressure of all other discharge plumbing components.
C. Flow Sensor
The flow sensor (paddle-wheel) measures the water flow through the foam manifold system
and sends the information to the Control Box and OIT Display. (Figure 6)
