Genuine Balboa Part

Manufacturers Code: 55048 - Balboa GL2000

The GL2000 is designed for a 3 pump or blower option -  first pump(1 or 2 (dual) Speed), second pump dual speed if no blower used, third pump or blower (if pump 2 is single speed), a circulation pump if required and the standard Ozone and 12 volt light. It runs on 230v at 50Hz and should be fitted by a competent individual or trades person.

This is for the complete control box only and doesn't include cables to connect pumps or topside controller.

Standard control panels used on this box are ML range such as the ML700 and ML900 panels.

This box is a great upgrade if you have an old GL2000 PCB housed in a metal box, because other than changing over to this box the only other thing you would need to do is change the cable ends.

You will receive the new black control box please note old grey is no longer available.

Replacing a Mach 2 with a Mach 3
Sunday, 12 August 2018  | 

The control box on my hot tub failed and the Mach 2 is no longer available so I bought the Mach 3. It has now been installed and is working perfectly. However be warned. The Mach 3 box does not align with the pipes by a good centimetre. The depth of the box has been changed to be deeper and the design change sets the heater forward about a centimetre. I had to cut a hole in the hot tub wall so that the Mach 3 sat further into its enclosure and aligning the heater properly with the existing pipes. The hole process of emptying the tub, carrying out the modifications and wiring in the control box, then refilling and switching on took me about three hours. Nice Saturday morning project.

I would give the product and HottubDIYs service a 5 star rating but knocked a star off for Balboa not considering the consequences of their design change .
