Multi System Operating Procedure (MSA)

Setting up the Water Management System

Hose connection

Position the Water Management System (WMS) adjacent to the Multi System

shower compartment, in an area which will not obstruct walkways or fire exits.

Remove the water hoses from the equipment box and uncoil each hose, 2 x 3mtr

hoses fitted with ½” hose connectors and 2 x 2mtr hoses 1 x fitted with ½” hose

connectors and the other open ended with one ½” hose connector.

The WMS has 4 x ½” male hose connectors located adjacent to the water filter

bottles built onto the side of the WSM. Each hose connector is identified for

connection.

1.Water In 2.Water Out 3.Waste In 4.Waste Out

Connect 1 x 3mtr hose to the Water In male hose connector and connect the opposite

end of the hose to the mains water supply outlet.

Connect 1 x 3mtr hose to the Water Out male hose connector and connect the

opposite end of the hose to the shower head male hose connector, located on the

shower cubicle external wall at high level.

Connect 1 x 2mtr hose (fitted with ½” hose connectors at both ends) to the Waste In

male hose connector and connect the opposite end of the hose to the shower waste

male hose connector, located on the shower cubicle wall at low level.

Connect 1 x 2mtr hose (fitted with 1 x ½” hose connector) to the Waste Out male

hose connector, extend the open ended hose to a drainage point and adequately

secure to prevent flooding. Where a suitable drainage point cannot be accessed,

waste water collection tanks should be used.

Electrical Connection

The WMS electrical specification requires 2 x 110v 16amp supplies

Remove 2 x 110v, 16amp, 5mtr extension leads from the equipment box, and also

the 110v, 16amp splitter box.

Connect the 110v, 16amp female trailing coupler of each extensions to both 110v

16amp mains inlet sockets, located on the front of the WMS adjacent to the control

panel.

Connect the 2 x 110v, 16amp plugs to 2 x 110v, 16amp socket outlets on the 110v,

16amp splitter box.

Connect the 110v, 16amp mains lead plug from the splitter box into the 110v, 16amp

socket outlet on the supply transformer.

On the WMS control panel located on the front of the unit, check that the mains

indication lamp has illuminated to confirm there is power being supplied to the

WMS.

Filling the water tank

The WMS has a self filling system when used with mains water supply. With the hose

connections and electrical connections made and powered the WMS will self fill and refill

automatically.

Turn on the mains water cock linked to the WMS, when the unit is powered a solenoid

valve in the unit will open and allow the water tank to fill automatically.

When the unit reaches its required capacity the solenoid valve will close until the water

level drops during its operation, this will then activate the solenoid valve and refill the

WMS

Where there are no means of local or accessible water supplies, the WMS will require to

be manually filled using fresh water canisters. When the water level drops below the

minimum operating level a low water alarm will sound to alert the operator.

Operating the WMS

Heating

The WMS control panel is located on the front of the WMS system, using the 3 position

selector switch, turn the switch to position 1, on the control panel the indication lamps for

power and heater on, should now be illuminated.

Set the water temperature thermostat on the control panel to the required temperature

(40 degrees as standard).

When the water has reached the required operating temperature the indication lamp for

operating temperature will illuminate.

Pump system

Turn the selector switch to the second position to activate the shower and waste pumps,

the shower pump will pressurise the shower hose and switch off, the shower pump is

controlled by a water pressure switch that will activate when the shower tap is opened

and the water runs freely, when the shower tap is closed the pump will stop.

The waste pump will run continuously whilst the shower pump is in operation and after

the shower pump pressure switch is activated, to ensure that all of the waste water is

removed from the shower tray.

The waste pump can be activated without the shower pump by turning the selector switch

to position 3.

Changing water filters

Regular checks of the waste water filter should be undertaken to prevent the failure of the

waste pump system.

Remove the filter bottle from the filter bottle bracket; turn the bottle anti-clockwise and

unscrew the bottle from the bracket.

Remove the filter bottle ‘O’ ring, located in the recess of the internal bottle housing.

Empty the contents of the waste water bottle into a red asbestos bag and follow your

company procedures to dispose of asbestos containing materials.

Refit a new water filter and replace the filter bottle ‘O’ ring; screw the water filter bottle

back onto the filter bottle bracket, the bottle must have a tight seal between the bottle

holder flange and ‘O’ ring seal to prevent any air leaking into the pump system.
