DESCALING PROCEDURE (REQUIRED)
Scale deposits on the interior of the heating system can cause a noticeable loss in heating
performance. Deposits of this kind result from hard water deposits. The frequency with
which descaling procedures are required will vary. If the area has particularly hard water,
you may have to descale often.
To descale the system, add an appropriate descaler chemical to the water box. Circulate
it through the system. Let it stand. Flush and repeat as necessary. Clean all screens and
strainers, and check them frequently following descaling.
If using TM DeScaler™ through the flow meter, make sure to run clean water
through the flow meter after this procedure.
To descale using the recirculation kit (P/N 000-078-058), start with an empty water box.
1. Fill a third of the water box with TM DeScaler. Follow the recommendations on the
TM DeScaler label for proportions. Verify that the float is not lying horizontal, but
floats below.
2.
Attach the recirculation fitting provided in the kit to the garden hose quick connect
(see Figure 11) and this combination to the front of the truckmount.
3.
Attach one section of the solution hose to the outgoing solution fitting on the front
of the truckmount and the other end to the garden hose and recirculation fitting
combination that is attached to the front of the truckmount. Additional hoses may be
attached inline if descaling of hoses is needed.
4.
Start the truckmount and allow it to run for 3 - 5 minutes. Do not leave the TM
DeScaler solution in the system. Flush the system with clean water and turn the
truckmount OFF.
