Cooler Maintenance – Replacing the Water Filter
Required items
 PH-10 hand pump
 Clean container, such as a bucket
 Latex Gloves (powder-free)

Secondary Cooling Water (or steam-distilled water)
NOTE: Replace the water filter and secondary cooling water every 6 months.
1. Remove the cover of the cooling water tank.
2. Remove the floating panel (keep the panel clean).
3. Pump the water out of the tank using the hand
pump.
4. Pull the water filter up and out. (The water filter is
pressed into the bottom of the cooling water tank.)
Depending on the date of manufacture, the water
filter may be in a slightly different location.
5. Insert a new water filter and then supply the
secondary cooling water with the hand pump, until
it reaches the HIGH line on the water level label.
6. Return the floating panel in the tank. Return and
secure the tank cover.
Cooler Maintenance – Refilling and/or replacing Ion Exchange Cartridge
 The Laser uses an economical ion-exchange cartridge. You can use it repeatedly by refilling its
contents, i.e., ion-exchange resin. Service life of the cartridge housing is about 3 years.
 Our high performance Ion-Exchange Resin is exclusively blended, so that it purifies more
effectively than conventional resin and has a longer service life.
TIPS
 Life expectancy of the ion-exchange resin is approximately 6 months. Generally it’s best to
replace the ion-exchange resin before the old resin becomes non-effective.
 If the ion-exchange resin is exposed to air, it will deteriorate. When opening the bag, put the
resin into the cartridge immediately and put back the cartridge into cooling water tank.
 Do not expose ion-exchange resin to direct sunlight; keep it in a cool place but do not freeze it.
 When replacing the Ion-Exchange Cartridge, use the proper replacement tool. Do not over-
tighten, or damage to the threads will occur.
 You can use the floating panel repeatedly. As the floating panel is made of polyethylene foam,
dispose according to all relevant regulations.
