K18 Simplygas
Guidelines for the preventive maintenance operations
Check of the unit
visually check of the general condition of the unit and of its finned coil √ (1)
check the correct operation of the device used for monitoring the water flow √
check the % value of CO
2
√
check that the condensate discharge is clean (If necessary, frequency of the main-
tenace operation must be increased)
√
replace the belts after 6 years or 12,000 hours of operation √
(1) It is suggested to clean the finned coil once every 4 years (optimal frequency of the cleaning operation is in any case strongly affected by the installation site). Avoid excessively aggressive
cleaning of the finned coil (e.g. high-pressure washer).

Emptying the system may cause damage due to corro-
sion of the water pipes.
Deactivate the system in winter
Should you intend to stop the appliance in the winter
season, ensure at least one of the following conditions:
1. antifreeze function active (Paragraph 3.5 p. 26)
2. sufficient anti-icing glycol (Paragraph 3.7 p. 26)
7.4.1
Prolonged periods of inactivity
▶
Should you foresee to leave the appliance inactive for a long
period of time, disconnect it from the electrical and gas
mains. These operations must be performed by qualified
personnel.
How to deactivate the appliance for long periods of
time
1. Switch the appliance off (Paragraph 6.2 p. 44).
2. Only when the appliance is completely off, power it off
with the main switch/disconnector switch (Detail GS in
Figure 4.2 p. 31).
3. Close the gas valve.
4. If necessary, add water with glycol (if the appliance is
disconnected from the power and gas mains, the active
anti-icing protection is missing, Paragraph 3.5 p. 26).
How to reactivate the appliance after long periods of
inactivity
Before reactivating the appliance, the operator/
maintenance technician of the system must first of all:
„ Check whether any maintenance operations are re-
quired (contact the TAC; see Paragraphs 7.2
p. 49 and
7.3 p. 49).
„
Check content and quality of the water in the system, and
if necessary top it up (Paragraphs 3.9 p. 27, 3.8 p. 27
and 3.7
p. 26).
„ Ensure the flue gas exhaust duct is not obstructed, and
that the condensate drain is clean.
After completing the above checks:
1. Open the gas valve and ensure there are no leaks; should
gas smell be noticed, close the gas valve again, do not
switch any electrical devices on and request intervention
by qualified personnel.
2. Power on with the main power supply switch (GS, Figure
4.2 p. 31).
3. Switch on the appliance using the provided control de-
vice (OQLT021, OCDS007 or external request, Paragraph
4.4 p. 31).
