page 44

), and visually check that water flows freely through the 

drain.

Perform water 

analysis.

X

Perform a water analysis on a semi-annual basis to ensure opti

-

mal performance. Refer to 

"Management of Scale and Chloride Levels" on 

page 48

.

Inspect tank, 

primary heat-

exchanger coils 

and drain fitting 

for scale build-

up.

X

X

X

Adjust 

Blowdown Rate 

and 

FTBD Interval

, as necessary, to reduce scale 

build-up.
Inspect the inside of the tank, and make sure that scale build-up 

does not exceed 50 mm. De-scale as required. Refer to 

"Cleaning the 

Tank" on page 51

.

Inspect sec

-

ondary heat-

exchanger (CS 

model only) for 

blockage.

X

X

Inspect water flow through the secondary heat-exchanger and make 

sure there is not blockage. Clean, if necessary – refer to 

"Cleaning the 

Secondary Heat-exchanger" on page 52

.

Inspect the condensate trap connected to the secondary heat-ex

-

changer for blockage. Flush and prime the condensate trap, if neces

-

sary – refer to 

"Cleaning the Secondary Heat-exchanger" on page 52

.

Inspect sacrificial 

anode in the

"Cleaning Hoses, Dual Fill Valves and Drain 

Pump" on page 54

.

Remove dust 

build-up on the 

blower housing.

X

X

Use an air gun to remove dust accumulation on the blower housing.

Inspect the

exhaust vent and 

terminal.

X

X

X

Check that there are no leaks in the exhaust vent, and it is not dam

-

aged or corroded excessively. Check the vent is secured properly 

and has the proper slope. 
Make sure there is no blockage in the exhaust vent including the 

exhaust terminal.
When operating in a stable state, make sure that flue temperature 

is 135-149 °C for the standard-efficiency model. Flue temperature 

should be 49-60 °C for the CS model.
