2. Introduction and Principles Of Operation
Thank you for purchasing this Dry-Deck 20 product from Pump Technology Ltd.
Since 1995 Whale have been the leading manufacturer of pump kits for use with shower trays and wet floors.
These kits have the reputation of working reliably for many years without requiring maintenance.
Section 1 above shows the product installation in an apartment with the components in an adjacent airing cupboard.
Look at your installation prior to fitting so that the pump, surge damper, control unit and sensors are in accessible positions.
Typical installations would have these components in an adjacent cupboard i.e. airing cupboard or in a false wall with an access panel.
Please note:
incorrect installation may invalidate the warranty.
Principles Of Operation
This Dry-Deck 20 control unit uses flow sensors to measure the flow rate of water into the shower.
The pump speed is controlled directly by the control unit which uses the signals sent from the flow sensors to adjust the pump speed to match the flow from the shower.
This minimizes suction noise at the gulley. A simple setup is required to match the pump performance to the characteristics of the installation.
3. Installation & User Warnings
Installation Warnings
| Before Installation read the instructions. |
| Contact the Technical Helpline (0845 0694 253) if you are unsure. |
| All electrical and mechanical components (control unit, pump and flow sensors) must be accessible after installation. |
| The MAXIMUM flow rate the pump is designed to work with is 20 Litres/Minute |
| Do not plumb the pump outlet into the waste piping that other appliances drain into as there is a risk of induced syphoning. Use an anti-syphon trap where necessary. |
| The shower floor must have a fall of 30mm in 1metre to the gulley. |
| Plumbing installations must comply to latest WRAS regulations. |
| The electrical wiring must conform to EU wiring regulations BS7671:2001 Amdt2:2004. |
User Warning
| It is advisable where the property is unattended for an extended period that the water supply to the shower is shut off. |
| If there is a reduction in pump performance after installation please contact your installer. |
Wet Floor / Shower Tray Warning
|
The Dry-Deck 20 system is designed to work on shower bases with an adequate fall to the gulley. We would recommend the use of pre-formed shower bases, i.e. Impey Aqua-Dec or similar. This eliminates the risk of puddling or insufficient fall to the gulley. Where the floor is being formed in the screed we recommend the following falls: 30mm in 1 metre 15mm in 500cm 7.5mm in 250mm Forming a shower base is a highly skilled task, do not attempt this if you are unsure. Where the fall is not sufficient the water will not refill the gulley rapidly enough and so suction noise will be increased dramatically. Call the Technical Helpline on 0845 0694 253 if you are unsure. |

1. Before mounting the pump refer to the
plumbing diagram in the next section for maximum pipe
runs. Mount the pump on a solid wall to prevent vibration. Use a back board if this is not possible. The pump is mounted vertically (See opposite) within 3m of the gulley. To aid servicing the head of the pump must be above the floor by at least 150mm (maximum height of 500mm). Fix the pump in position through the feet with the screws and washers provided. |
|
|
2. Rotate the pump head if necessary to give a straight
run of pipe to the waste. Loosen the clamping rings on the pump
head and rotate the head before retightening clamping rings. Note: Do not remove the pump head. |
|
| 3.
Push fit fittings are provided to connect the pump to inlet and
discharge pipe work. All pipe work in and out of the pump must be in 22mm. Ensure fittings are locked after the pipe has been pushed home. |
|
| Only one vertical lift on the inlet to the pump and the discharge from the pump is allowed. |
| When laying the pipe under the floor use only slow radius bends. |
| Use slow radius bends above the floor if possible to ease the flow of water and reduce loading on the pump. |
| Use of copper pipe is recommended to reduce the risk of air leaks at connections. |
| Ensure edges are burr-free. Burrs may cause a build up of hair etc. that will reduce flow. |
| Pipe work must be secured to prevent any vibration and noise. |
| Twist lock the securing ring on the push fit fittings (If semi rigid pipe is being used follow the manufacturers instruction to prevent air leaks). |
| Use silicone on
top of the seal to ensure proper sealing beneath tray. Using the
hand tool provided to tighten the locking flange, fit the gulley
cover into the sockets and push down with the palm of your hand to
secure. When fitting in solid floors, remove enough concrete for the installation of the waste water pipe and gulley. Where copper pipe runs under the concrete it must be lined to protect and prevent corrosion. Leave the hand tool in place to prevent building debris, grout etc. falling into the gulley. Only remove the hand tool and fit the gulley cover when the installation is complete. For alternative gulley options Click Here. |
|
| Where the
situation demands or if the pipe
run is greater than that specified for the Whale pump a macerator
pump may be used.
Contact the technical helpline (0845 0694 253) for assistance. The discharge from the pump must go into the top of the macerator box and not into lower side entries. DO NOT USE the bottom entries. It is preferable to have two separate discharge lines to waste and drainage when used in the same room as a macerator pump. Warning:- Failure of the macerator will not be detected by the Whale Pump. |
|
| Fit the Flow
Sensors with the arrow in the direction of flow to the shower,
downstream of any other connections to the water supply. Each sensor
must be protected by a filter which is supplied in the kit. The flow sensor must be mounted in a straight length of unstressed pipe.
Failure to comply will invalidate your warranty.
|
|
| Locate the
control unit outside the showering area (as per BS7671:2001 in zone
2 or 3, refer to the drawing) The control unit meets IP45. Tighten all cable entry grommets, even unused ones, to seal the Control Unit. Connect Control Unit to 240v AC supply via a 5 amp fused spur. |
|
10. Schematic of Dry-Deck 20 Components
| Switch off the power to the
control unit while making connections. Mount the control unit in a position where it is not easily accessible to the user. The enclosure is IP45 rated and may be mounted in zone 2 of the bathroom. Strip wires 10mm and twist prior to inserting into the spring loaded contacts. Push contact arm back with a finger or small screwdriver before inserting wire and then release. Check for a good connection by gently tugging on the wire. 1. Connect pump supply wires to the Pump Red and Pump Black connections. 2. Connect flow sensor to sensor connections using the colours as indicated on the controller board. For the cold supply use FS1 and for the hot supply use FS2 connections - see diagram on the right. |

| 1.
LED Display:
When not in programming mode the display shows
' - -
' Water flowing through the flow sensor is indicated by alternately flashing ' flow rate ' for flow sensor 1 and ' flow rate ' for flow sensor 2. When no water is flowing the display flashes ' - - '. Flow rate is displayed in 0.1 litre increments up to 10 litres and then 1 litre increments. |
|
| 2. Flow Rate Display: When the system is not in status display mode or configuration mode, it will display the flow rate on the 7 segment LED's With no water flowing the system will display ' - - ' momentarily every few seconds. With water flowing the system will display the following: Sensor 1 flow rate, Sensor 2 flow rate, Combined flow rate.... repeating Flow rates up to 9.9 litres/minute will be displayed to 1 decimal place. Flow rates of 10 litres/minute and above will display the rate as the nearest whole number. For Example: 3.4 litres/minute on inlet 1 - LED shows "3.4" 7.5 litres/minute on inlet 2 - LED shows "7.5" Then total flow is displayed - "11" |
|
| 3. Solenoid Switch: See Diagrams 1.13 and 1.14 below. Aux 1 is for connection to a momentary contact switch. When the user closes the switch Solenoid 1 and Solenoid 2 are energised for 30 minutes. This allows water to flow through the shower. If the switch is closed again the 30 minute timer starts again.
|
|
| 4. Pump Run Switch: See Diagrams 1.13 and 1.14 below. Aux 2 is for connection to a momentary contact switch. When pressed the pump runs for 2 minutes and enters the over run cycle. This may be used where the wet room is washed down and water needs to be pumped away. |

13. Principles Of Operation - Four Stages of Controller Operation
| 1. Pump Start: The pump controller measures the volume of water released into the shower tray. The installer sets this volume so that there is water in the gulley before the pump starts thus preventing any start up sucking noise. |
| 2. Pumping flow rate: With the shower running at a mid flow (8 litres/minute) setting the installer adjusts pump speed to match the flow of water into the tray. This is done by watching the level of water at the gulley and adjusting the speed up or down as required until the water is being pumped away slightly faster than the flow from the shower. |
| 3. Pump Speed Narrow setting: The pump speed-narrow setting is used to set the pump speed at 2 litres/minute increments above 8 litres/minute up to the maximum flow from the shower. This is necessary as flow characteristics from the pump change at higher rates. |
| 4. Pump Shutdown: After the pump speed is set the shower is turned off. When the water is drained from the tray a gurgling noise is heard. The electric current loading on the pump is then stored for subsequent use in automatically turning off the pump. |
|
How to adjust settings: a. Pressing the Mode button will switch between the various mode settings, indicated by small LED's. b. The Up and Down arrows are used to adjust the value. c. Press down the Mode button firmly until the LED flashes which indicates that the selected value has been stored. |
| Switch power on to the control unit - the LED's will blink alternately. A simple setup is all that is required for trouble-free efficient performance of the Dry-Deck 20 system. |
|
|
|
Inlet Pipe Size:
Programme in the size of pipe work from the gulley to the pump. Select 22mm. Ignore the 15mm setting as this is not used for this application. With '22' illuminated on LED's hold the mode button down firmly until the LED blinks. Note: This will also reset all the factory default settings including the pump speed. |
|
Pump Start Up: Start
Delay (litres):
This selects the initial amount of water in the tray before pumping starts. This should come above the level of the gulley. (Factory default is the minimum setting of 0.4 litres). Pressing the Up arrow will increase the amount of water from 0.4 litres to 5 litres passing through the shower head before the pump starts. Make adjustments to this setting during final commissioning. |
|
Pumping Flow Rate:
Pump Speed Settings: Prior to making adjustments turn the shower on and wait until the pump runs. Set the shower flow rate to 8 litres/minute. Watch the level of water within the shower using the gulley cover as a guide. If the water level is lowering then reduce the speed of the pump by pressing the Down arrow. Use initial increments of 5 until fine tuning is required. When the water level is rising then increase the speed of the pump using the Up arrow. After making a change watch the water level. Wait at least 30 seconds, as the system needs to stabilise, until you see if the water is rising or falling. When the water level is slightly over pumping, program in the speed setting by pressing the Mode button firmly until the LED blinks. |
|
Pump Speed - Narrow setting: This setting is required for higher flow rates. a. 'Pump speed' must be set first as per above using a mid-range flow setting. b. Increase the flow from the shower in increments of 2 litres and watch the water level around the shower gulley. If this is rising or falling over time make adjustments until a constant level is observed then programme in the setting. c. This process is repeated in 2 litre increments. The narrow adjustment corrects the flow rate over a band of 1 litre/minute either side of the flow rate that is being calibrated. |
|
Pump shut down:- Over Run (Auto Sense) preferred option To set Auto Sense Over Run (indicated by 'AS' on the LED) you must turn off the shower when you have selected this mode. When the pump is drawing air there will be a gurgling noise at the gulley, press down the Mode button so the controller stores the loading on the pump at this point. |
|
Pump Shut Down:- Over
Run (Fixed) Alternatively to set a fixed Over Run delay use the Up and Down arrows. Each digit represents a delay of 5 seconds (i.e. 2 = 10 seconds over run). Hold the Mode button down to program. |
|
a. All push fittings must have the twist lock in the locked position. b. Check all plumbing for leaks. c. Check waste water plumbing for leaks while pump is running. d. Ensure flow sensor is unstressed. After programming all the settings, turn the shower on and check for correct operation. Make final adjustments to the Start Delay if required. Note: 15 minutes after showering is finished, the pump will switch on for a brief period in order to remove any water that may have pooled. |
| The Whale Gulper
pump uses a single membrane to pump the water away. On the suction
stroke, water and debris are drawn in through the inlet valve. With
a chamber full of water the pump discharges the water through two
non-return valves on the outlet. The two outlet valves protect the
pump against losing prime. The aggressive flushing keeps the pump
valves clear of debris resulting in a pump which does not require
regular maintenance. Unlike other pumps, the Whale Gulper has the ability to run dry without causing damage to the pump. An additional advantage of the three non-return valves in the pump head is that no smells can be passed back from the waste stack into the shower area. |
