Qualified engineers that are registered to the relevant gas
authority standard must carry out all work.
HOT WATER COIL
At the start of the heating season, check the following :
- There is sufficient water in the system
- The battery has been correctly drained
- The percentage of antifreeze proportion is sufficient for
the degree of protection required.
CONDENSATE TRAY AND DRAIN TRAP
The trag must be free of sediment and dirt which could block
the movement of condensation. Check that the siphon is
not obstructed. This inspection must be carried out at least
once a year, preferably at the start of the air-conditioning
season.
ELECTRICAL TERMINALS
At least once a year :
- Power down the machine, blow away any dust from inside
the unit, and check and tighten if necessary the connec-
tions.
- Power up the machine, test the safety mechanisms.
- An analysis of the terminal in operating mode can throw
light on any strange noises from the contactors or other
units. Foreign bodies can disrupt the operation of the
components and causes noisy vibration.
To avoid accidents, remember that this type of
maintenance requires electrical expertise.

4. Clean blower wheel blades with a small brush and wipe
off any dust from housing. Clean accumulated dust from
front of flue box cover.
5. Return combustion air fan motor and vent connector to
original location and secure with retained screws. It is
recommended that the combustion air fan gasket be
replaced during reassembly.
6. Clean combustion air inlet louvers on heat access pa-
nel using a small brush.
HEAT EXCHANGERS
The performance of your equipment is directly linked to the
state of the heat exchangers, and it is therefore important to
ensure that they are cleaned regularly.
EVAPORATOR COIL (INTERNAL)
The exchange area must be kept clean at all times. It is
protected by the filters. If the filters are well maintained, the
battery will only require occasional general cleaning.
A brief inspection should be carried out when servicing the
filters.
CONDENSOR COIL (EXTERNAL)
The condensor coil is not protected by the filters. The
cleaning schedule is directly related to the environment in
which the equipment is operated. A brief inspection should
be carried out when servicing the machine. Cleaning can
be performed using compressed air or a soft brush.
Maximum caution is needed as the aluminium fins are
relatively fragile.
However, this type of cleaning is sometimes difficult and
relatively ineffective because the clogging is caused by a
mixture of grease vapour and powder. For this reason we
would recommend cleaning with PRESTOSOL, a de-
greasing agent with very low toxicity, non-flammable and
which does not corrode standard metals.
As a rule, it is sufficient to apply the product to the fins,
moving up and down and from left to right (as if you were
painting it). If the coil is very blocked, it may be necessary to
wait a few minutes after first applying the product and then
continue.
This cleaning must be performed when the machine is
switched off. In addition, prior to restarting the machine, we
recommend waiting until the coil is fully drained and the
solvent has totally evaporated.
SUPPLY AIR FAN IMPELLOR
Annually inspect supply air fan impellor for accumulated dirt
or dust. Turn off power before attempting to remove access
panel or to clean blower wheel.
