CalMag CALULTRA 132, Owner'S Manual

System Sizing:
All CALMAG YORKSHIRE LIMITED UV systems are rated for a specific flow rate under specific water quality
parameters. The equipment has been designed to ensure that the appropriate dose will be delivered
provided all outlined parameters are met. PLEASE NOTE that unless a flow restrictor is part of the
installation, the system may pass more water through the system than what the system is rated at. If this
happens, the system may be delivering a UV dose level that is below what may be expected. As a result,
the maximum flow as specified in the equipment specifications should be strictly adhered to (a lower flow
is not a concern as the dose will increase due to a longer contact time).
It is important to know the maximum flow rate that your water system delivers. If you do not have this
information you can simply fill a 1 gallon bucket with water from a faucet and time how long it takes to fill
up. This will be the maximum flow rate for that particular water system. The appropriate Calmag UV unit
should then be chosen.
PLEASE NOTE: It is always better to oversize your UV system than to undersize. For example, if your
pump delivers 190 litres per minute it is recommended to install the CALULTRA 220 UV unit. There will be
occasions where your home is using water at the pump’s maximum capacity.
Location:
Step 1: Find a suitable location to mount the UV chamber and the accompanying control panel. In
choosing your location ensure that the panel is located within 5 feet of a ground fault circuit interrupter
(GFCI) and that there is easy access to the main cold water line prior to any branch lines and before the
hot water heater. The panel can be up to 8 feet away from the chamber or a maximum of 5 meters if
custom lamp cables are ordered (for an additional cost). If you have any other water treatment
equipment, such as a softener or water filter, ensure that the UV is the last piece of treatment equipment.
PLEASE NOTE: All CALMAG YORKSHIRE LTD UV disinfection systems are intended for indoor use only as
they should not be exposed to the elements.
Step 2: There are two different CALULTRA control panels, depending on which system is purchased. The
three single lamp systems (“35”, “55” and “85” series) use a control panel that is 30.0 x 20.0 x 16.0 cm
(11.8 x 7.9 x 6.3") in size (see Figure 2), while the three two-­‐lamp systems use a control panel that is 40.0
x 30.0 x 16.0 cm (15.8 x 11.8 x 6.3") in size (see Figure 3).
