ROLLER IN-POOL DETAIL

1. WHY A SLATTED COVER?

As a swimming pool owner the importance of keeping a pool covered is of paramount effect for maintaining cleanliness / minimizing of water evaporation / heat retention and often safety.

The slatted cover is considered to be superior over the normal “BUBBLE” or “SHEET” types of covers available and is generally considered to be a permanent solution in the covering of a swimming pool.

In operation (either manual or automatic) its ease of use must be considered of utmost important to the owner. Its lifespan of 10 Years (minimum) easily offsets the initial capital costs incurred.

The slatted type cover, being Individually made to suit a particular swimming pool, ensures customer satisfaction at the outset.

Availability of various colour options / in or above ground variants / manual or automatic operation allows for the option most suited to your particular environment.

2. THE PRINCIPLES OF OPERATION

The operation of the slatted cover is such that the cover “FLOATS” on the surface of the water and fits snugly under the coping edge surrounding the swimming pool.

In manual design the cover is easily operated by an individual person and has NO connecting ROPES or fixing HOOKS to contend with. The manual design is specifically for ABOVE pool operation and is considered to be the easiest system for existing swimming pools. Simply fitted at one end of the pool it is securely mounted in a permanent position.

In automatic design the cover is simply operated by a purpose designed motor which is either KEY operated, or, in the DELUXE version by simply using a REMOTE. (Similar to the operation of a garage door or electric gate).

Again the system has NO connecting ROPES or fixing HOOKS to contend with. The automatic design is suitable for use on both ABOVE or IN pool operation and is considered to be ideally suited to new swimming pool construction.

Manual systems fitted to ABOVE pool systems CAN be converted at any stage to being motor driven.

3. SELECTING A STYLE FOR YOUR POOL

The selection of a suitable operating system for your swimming pool can be clearly seen from the schematic details shown below.



4. HOW THE “ROLL A SLAT” WORKS

As can be seen from the above variants the slatted pool cover simply UN-COILS itself onto the waters surface, travelling toward the opposite end of the pool, until the whole pool is covered.

All individual slats are inter-connected to each other and when uncoiled are gently pushed from the coiled end to the opposite end as the roller system is operated manually or automatic.

As the slats are individually purpose made to suit a particular pool size it is ensured that the whole pools width and length is covered.

As the slat widths are made to the exact requirements of the pool, fit under the coping edge surround, no unsightly gaps are seen, due to poor fitment or cutting, as can be found with use of other types of cover material.

5. POOL VARIATIONS

Traditionally pool construction in South Africa has tended to be towards irregular shapes, large in overall size, and generally sited away from the main house / entertainment area.

Over the last decade these traditions have changed considerably and recent pool construction tends to be of more uniform shape, smaller in overall sizing, sited in close proximity to the main house and are generally a full time part of the home entertainment environment.

Heating and covering of Swimming Pools is now commonplace and the slatted pool cover designs are ideally suited to this type of construction and environment. Its HEAT retention properties are, due to its design, ideally suited to those HEATED swimming pools.

Although every type and size of pool cannot be detailed in these pages the most common variants are as indicated below.


Non-standard shapes CAN be catered for subject to prior Inspection.

Roll-up Position and direction are generally as indicated above.

On rectangular and Square pool shapes, the Roll-up can be located at either end but DEEP end use is recommended as the Roll-up station’s will generally be “FIXED” in position at the time of installation.

Slatted type covers for new pool construction can most easily be inbuilt at the design stage and generally of the AUTOMATIC variant.

Should you be in the DESIGN stage of pool building the “ROLL A SLAT” and swimming pool can be a packaged design to suit the conditions of the client.

Growing in popularity is the design of pools using an OVERSPILL system for great aesthetic looks. The “ROLL A SLAT” is ideally suited to this type of construction, as it will NOT tend to fall over the OVERSPILL section.

6. SLAT MATERIAL / DESIGN

The slats used in the “ROLL A SLAT” system are made from a high grade ‘u’ PVC rigid material fully UV (ultra-violet) stabilized material ensuring long life and durability suited to the harsh South African weather conditions.

Each slat is individually made to a predetermined width and sealed at time of factory assembly with a specially designed “END CAP” to ensure that the slat does not allow water to enter into its cavities thus ensuring utmost buoyancy when installed on a swimming pool.

The end cap serves as an added buffer-protection to the individual slats from scraping against the swimming pool sides.

Each slat has three (3) individual cavities across its entire length, which, being AIRTIGHT allow for good insulation against heat losses whilst providing for some partial additional heating for the pool water.

Although the standard (and most common) colour is ‘OFF-WHITE’ the other standard colours available are ‘LIGHT BLUE’ and ‘MID GREY’.

In fact the “ROLL A SLAT” could be provided (on a made to order basis) in a range of colours to suit specific requirements.

7. ROLLER SYSTEMS

The roller system is supplied in two (2) formats, being 1, for ABOVE POOL and 2, for IN-POOL systems.(ABOVE POOL)

For the above ground system the main roller tube is ALUMINIUM with all hardware / shafts, bolts Etc being Stainless Steel. The side mounting plates are generally fabricated from mild steel plate which is then galvanized and finished with an electrostatic epoxy power coating, protecting against corrosion from pool chemicals / salt water (as in salt chlorinated pools).

The stand assembly is, after assembly, enclosed by means of a cover fabricated from a UV stabilized ABS (plastic) cover to prevent contact with any moving parts by the user.

If the installed “ROLL A SLAT” system is used on outdoor pools a variety of cover designs can be supplied as added protection against UV conditions when the cover is to remain in the rolled-up position for long periods.

In indoor pool applications this is not considered to be a standard requirement. (IN POOL)

The IN-POOL design main roller tube is STAINLESS STEEL, or, in certain cases, PVC coated anodised Aluminium (not suitable for salt water chlorinated pools).

All other components are standard supplied in STAINLESS STEEL or a PE (polyethylene) synthetic material to prevent corrosion.

ELECTRICAL MOTOR DRIVES ARE ALWAYS FITTED EXTERNALLY TO THE POOL
PREVENTING ANY POSSIBLE ELECTRICAL CONTACT WITH SWIMMING POOL WATER

8. MOTOR DESIGN

If the AUTO option is used the MOTOR drive is of a totally enclosed design operated by a 12 Volt DC motor. This motor is suitable for operation in Swimming Pool environments and does NOT pose any possibilities of electric shock.

The 12 Volt motor circuits have a battery back up for use when mains power has failed or tripped for any reason. This ensures that the “ROLL A SLAT” will never be inoperable when mains power is unavailable.

As an added feature each MOTOR drive is fitted with a CLUTCH mechanism that if mains and battery power fails the cover can be pulled on or off the pool manually.

9. GENERAL

The design of the “ROLL A SLAT” pool cover is intended to be a permanent solution to effectively bring you the full benefit of your swimming pool.

Effective in not only keeping your pool clean the “ROLL A SLAT” virtually eliminates evaporation, retains HEAT in your pool, reduces chemical usage and overall maintenance is minimized, whilst at the same time is designed for EASY and SIMPLE operation.
