hose, using good velocity sprayed directly on the pleats.

WATER QUALITY
Maintaining balanced water chemistry is important to the life of
your pool pump. This pump is designed to be used with Pool & Spa
water, balanced in accordance with Langlier Saturation Index, with
a pH level of between 7.2 and 7.6 and is regularly treated with a
chlorine sanitising agent with the level not exceeding 3PPM.
Please consult your local pool shop regularly to have your water
tested.
NOTE: Algae, calcium, clay, sun tan oil and body oils can form a
coating on the element which may not be easily removed with
normal hosing. These materials can be removed by soaking
the element in a de-greaser and/or de-scaler. Your local Davey
Dealer will be able to recommend suitable products.
Failure to undertake regular maintenance may cause damage
not covered by warranty.
