See Figure 9. The battery is located in the USB port / battery compartment (arrowed) next to the control
panel on the base of the fixture.
To replace the battery:
1. Disconnect the fixture from AC
mains power and allow to cool.
2. See Figure 10. Push down on the
locking tab (arrowed) with a
screwdriver to release the USB
port / battery compartment cover
and remove the cover.
3. Remove the used battery and
insert a new one of the correct
type, respecting battery polarity
(positive terminal facing
downwards, away from the
head).
4. Reinstall the compartment cover and check that it is closed securely before reapplying power.
Send used batteries to an authorized waste recycling center for recycling. Do not treat a battery as
household waste.
Head air filter
The MAC Ultra Performance is protected from the entry of dirt and dust by an air filter in the head. Free
airflow through filters is important for effective cooling, effective performance and maximum product life. Air
filters therefore require periodical service.
Two types of air filter are available from Martin suppliers as service items for the MAC Ultra Performance:
• Re-usable air filters with a metal element, available as single filters (P/N 5132434-00).
• Disposable air filters with a paper element, available in sets of 12 filters (P/N 50400765).
Regardless of which type of filter the fixture is supplied with, you are of course free to choose which type
you will use. The metal filters can be cleaned and re-used. Note that the filter mesh is not as fine as with
paper filters, so the fixture may require internal cleaning at shorter intervals than you are used to.
Air filter service intervals depend on the environment the fixture is used in. Inspect air filters visually at
regular intervals. Clean the fixture’s metal re-usable filters – or replace paper filters – if they are visibly
contaminated by dust, dirt, residue from atmospheric effects, etc.
To service the head air filter:
1. Disconnect the fixture from power and allow components to cool for 30 minutes.
2. The air filter is located in the left-hand side of the head. Position the head so that the air filter cover is
accessible and apply the tilt lock (see Figure 1 on page 7).
3. See Figure 11.
Unclip the air
filter cover and
lift it off the
head.
4. Remove the air
filter from its
recess in the
head.
5. Dispose of
paper air filters.
Do not try to
clean or re-use
a paper air filter.
Clean metal air
filters with a soft
brush and vacuum cleaner or compressed air, taking care to avoid damaging the filter mesh. If metal
filters are greasy, you can clean them in a household dishwasher at maximum 50° C (122° F), short
cycle recommended. Dry them completely before reinstalling. The metal filter is designed to be re-used,
but replace it with a new item if it is not in clean, undamaged condition after cleaning.
