Question about Scubapro Scuba Diving & Snorkeling

1 Answer

I am in thailand at the moment. My MK 20 ultra light first stage filter and keeper lock ring (?) came out and were lost. I got a service kit and want to know if I can simply drop the filter in and push the lock ring down on top. Is there any more to it then that? Please advise! Thanks Dan from Utah

How do i go about replacing the uv light

obtain proper replacement bulb
shut down entire filter for a moment before unscrewing the top locking ring off Uv filter (left turn) lift top off set asside
using a soft clean rag retract uv tube from its cylinder holder inside , remove power connector from tube end (you should have already removed all power from converter box) with extremely clean rag handle new tube ( allow no forign material to touch outside of tube ) reinsert power connector onto new tube (same way it came off old one) then reinsert tube into holder sleeve , route power cord to proper places away from lid , replace lid and install lock ring back with enough force to ensure a leak proof seal , re start pump ck for leaks if none found then restart power converter for Uv filter

How do i install a moen stem replacement kit part 97479?

make sure you turn the stop under the cabinet off use an allen wrench to take the handle off pull the keeper off the old cartridge pull the old cartridge out and make sure you put stem grease on the o-rings before installing the new cartridge or you will cutt the o-rings and ruin your new cartridge. put you keeper back in and reinstall your handle. turn your water valve back on underneath and enjoy.

What is 'install mk'?? what is mk?

MK is maintenance kit. It is a kit of items that need to be replaced ie drums/fusers etc. Hopefully you will have a service contract which includes this item as you may well find the cost too much?

KYOCERA fs-1920 Has the message instal MK coming up? Dopes this mean order a maintenance kit?

It means the page count has triggered this message.
You _should_ get a maintenance kit.

But if you simply can't take the time/money, you'll find a new menu item in the menus after service. the new item is 'maintenance', get to there and press enter. (May need to press enter twice), the menu item, flashing light, and install MK message will all disappear.

My 05 crf 250r will only start when pull started

it's your intake valves honda uses a titanium intake valves while it saves .999 pounds it IS there down fall. The valves start to recesse into the head, which we know will cause the clearance to get smaller. A.P.E offers a great fix, its a rebuilt head port and polished to stage 2 specs. with stainless steal valves springs and new keepers. While your there it'll give you a chance to see how things are doing on the top end of your motor, pull your cylinder and check your rod the gasket kit comes with a base gasket too so take your and build it right. this is also a great to replace your rings and hone the cylinder or better yet put a bore job on the to do list.

Message stating install MK

You have done more than 300,000 pages. I wouldnt waste your money on a Maint Kit, just stretch it out by doing the following.

Press Menu/Ok (Main menu)
Go into [>>Service]
Then press the right arrow.
Then find [>> Maintenance]
Press the ok key, then it will show [>> Maintenance?]
Press the ok key twice, and it will reset all the counts on your consumable components (Drum, Developer, Transfer Roller, ETC)

Extreme loud sound on MK/25

did you check your bulletins from scuba pro ? depending on the actual year of mfg ( you can call scuba pro and give them serial number )
there was a retro fit kit made for the mk 25 first stage of you send me your email i will send the bulletin to you

other wise if you wew working from an earlier service guuide then you would notbe aware of the retro fit kits and pistons some of the earlier schematic will not show you that o ring that you were refering to
