RC9 – INTRODUCTION
Before starting up your RolaChem controller, pool and spa water must be balanced correctly. The correct levels can be seen
below. This appliance is not designed to bring a pool into balance; it is designed to maintain a balanced pool.
Allow 24-48 hours after switching on unit for sensing and dosing to be 100% accurate, the inbuilt fuzzy logic controller
bases its precision dosing of chemicals by looking at historical dosing rates. After 24-48 hours, unit should be work at its
optimum performance.
Recommended chemical ranges (depending on pool location and pool surface) are:
CHLORINE: 1 - 3ppm
pH 7.2 - 7.8
STABILISER: 30 - 50 mg/L
TOTAL ALKALINITY: 80 - 150 mg/L
CALCIUM HARDNESS: 90 - 300 mg/L
PHOSPHATES FREE
PLEASE READ ALL THESE INSTRUCTIONS CAREFULLY BEFORE INSTALLING & OPERATING THE UNIT AND LEAVE THE
MANUAL ON SITE FOR OWNER/OPERATOR’S USE.
RolaChem dosing systems should operate only when the pool filtration system is running. The unit must not be connected
without adequate earth connections and a voltage other than 230-240V (unless specified otherwise)
Before installing the unit in position on the wall or post, the length of the PVC tubing provided should be
measured and taken into consideration. To avoid loss of water from the system, close all stop valves before
cutting any lines.
Connection of lines (see illustration page 5)
Install the Inline Mixing Chamber into the “return’’ line. Cut an appropriate piece out of this line and glue the
mixing chamber in position, using a PVC adhesive. Thread the PVC tube through the hole in the cap or
shoulder of the chemical container and fit the non-return or check valve and the weight. Ensure that the non-
return valve is fitted correctly (arrow indicates the direction of flow) Drop the weight, with the non-return
valve into the bottom of the container.
TIP: Soaking the ends of the PVC tubing in hot water or gentle heating with a lighter makes it easier to push
onto the barb. When installing chemical containers (especially acid), in filter enclosures, which have no
ventilation, it is recommended that the hole in the cap of the container is cut to fit tightly around the tubing,
so that fumes from the acid or chlorine will not corrode the equipment. It will be necessary to drill a second
hole in the cap fitted tightly with a length of tubing which should then be vented outside the filter enclosure.
This procedure is recommended only where the filter enclosure has no ventilation and is to protect the
equipment.
Note:
The appliance is not intended for use by young children or infirm person without supervision. Please ensure that young
children are supervised to ensure that they do not play with the appliance.
If the supply cord is damaged, it must be replaced by the manufacturer or its service agent or a similarly qualified person in
order to avoid a hazard.
Power to this controller must be either;
Supplied by an isolating transformer
Supplied through a residual current device (RCD) with a rated residual operating current not exceeding 30mA
IMPORTANT: RolaChem pumps dose against a maximum pressure of 150-175 kPA (20-25 psi), avoid excessive pressure
situations such as:
In-floor cleaners (when using for pool applications): The recommended position of the injection point and probe is on
the suction line.
ACID SHOULD BE DILUTED MINIMUM 1:2, MORE DILUTION IS OK
ALWAYS ADD ACID TO WATER (NOT WATER TO ACID)
NEVER MIX CHEMICALS
CHEMICALS MUST BE STORED IN ACCORDANCE WITH RELEVANT STANDARDS AND DANGEROUS GOODS
CODES. CONSULT YOUR AUTHORISED BUILDER OR POOL SHOP TECHNICIAN FOR ADVICE.
