Twist the water filter counter-clockwise to remove it, it may be a little stubborn.
When you have the old filter out, the installation cap will slide off of the filter. Compare it to the new filter and make sure that the fittings and seals match from the old filter to the new water filter.
When you have the filter out, compare the new filter with the filter you removed. Look for any differences in the filter that would inhibit it’s ability to install it.
If the filters are functionally identical, place the cap on the new filter, gently slide it into the hole, gently push it in and twist it until you feel the water filter mounting lugs catch and then turn it clockwise to secure the water filter. Only twist the filter until it is snug, do not force it. When you are using an after-market water filter it may not line up as the original, this is ok.
