Delta Dual V4/V6

1.0 Dual V4/V6 Overview

The Delta Dual V4/V6 is a packaged pump station designed to collect ground water via perimeter channel or Delta
129 detail and/or clear opening to the top of the chamber - please visit our website for water collection details.
Typically, the Dual V4/V6 would be used to collect ground water from a basement up to 150m² and/or surface water
from a light well up to 12m² to a maximum head of 7m and 9m respectively.

The pump station has been specically designed for below ground applications. The chamber is manufactured from

HDPE and when installed correctly, it is able to withstand hydrostatic forces encountered in high water tables.

The pump station is delivered as a complete package including, the chamber, internal pipework and two powerful
V4/V6 pumps. It is designed to be installed by contractors with competent building, plumbing and electrical skills.

The pumps operate by xed arm oats, the duty pump is set at a standard height (210mm to base of oat) and the
backup pump is set at a high level (380mm to base of oat). The high level alarm (where tted) will operate if the duty

pump fails leaving the backup pump to discharge water.

A high level alarm (DMS-270) is oered as a recommended extra to alert the property occupant when the water level
in the chamber becomes too high. A battery backup (DMS-320) is recommended to power the pumps during power

outage. Please see section 2.1 for more details about optional extras designed for the Dual V4/V6 pump station.

13.0 Maintenance

British Standards requires pump chambers to be serviced on a regular basis to ensure reliable operation of
equipment. PPS recommends that the pump station is serviced biannually.

PPS strongly recommends that a service agreement is taken out, please see the back page for further information.

14.0 Health and Safety

In order to minimise the risk of accidents when installing and servicing pump chambers, the following health and
safety guidelines should be followed:

• Obey all health and safety hazards.

• Observe strict cleanliness.

• Ensure power to the pump chamber is isolated before carrying out any maintenance to the pump chamber.

• Always ensure correct PPE is worn.

• All personnel working with sewage chambers must be vaccinated against diseases to which they may

be exposed to.

• A rst aid kit must be close to hand.

15.0 Guarantee

The Dual V4/V6 pump chamber comes with a 12 month component guarantee, which covers any manufacturing faults
and defects as a result of poor workmanship.

Pump chambers that have not been commissioned have a 12 month component guarantee from date of delivery.
Pump chambers that have been commissioned have a 12 month component guarantee from date of commissioning.

Any defects or malfunctions should be reported to Delta Membranes immediately to avoid any damage to other
components. All broken components must be sent to Delta Membranes at the customers cost. Any pumps to be
retuned must be returned complete with their cable attached.

We exclude all liability for any consequential or other damage or losses which may occur. We will not be liable if

the pumping system fails due to it having been incorrectly specied (e.g. where a pump is subjected to ow rates
higher than recommended or where a pump is used to discharge inappropriate uids/solids, such as building
debris or materials).

For technical support, please call 01279 757400 23

16.0 Troubleshooting

Please ensure the installation process has been completed thoroughly and all steps have been followed correctly.

Use the table below to assist with troubleshooting and if problems still occur, please contact PPS for further technical
support on 01279 757400.

Fault Cause

Water leaking from discharge arms. 'O' rings missing or not installed correctly in unions.

PTFE tape not applied to male irons on discharge arms
when attached to pumps.

Pump isn't running. Pump hasn't got power - check wiring with reference to

section 12.0 wiring diagram.

Float arm isn't lifting - check oat arm is free moving

and not catching on chamber or other pump - make sure
pumps are positioned as diagram 36.

Float arm not turning on pump - can you hear a click
when lifted slowly? If not, call PPS for further assistance.

Pump running but not pumping water or discharging

very slow (more than 40 seconds to empty chamber.

Pump is tripping. Pump is wired incorrectly or not on a separate supply -

Gate valve isn't open or partially closed - turn valve
anticlockwise to open.

Pump is air locked - make sure there is a level of water
to the top of the pumps, remove pump from union and

lower back into water, lift oat arm to activate pump

before reconnecting to discharge arm.

Discharge pipe is blocked - a drainage company is
required.

Pump impellor is jammed - turn o power and isolate

pump, remove pump from chamber, unscrew pump base
using Torx screwdriver and free impellor.

WARNING! - Insure mains power and pump is

isolated before taking pump apart and seek advice

from a qualied electrician.
