NOTE: If the pump is wired into a time clock or another automatic
control, the wiring should be removed by a qualied electrician.
NOTE: When making any enquiries about your Power Master
®
be
certain to quote the model number from the nameplate located on
motor.
IMPORTANT NOTE:- THREE PHASE MODELS ONLY
BEFORE FINALISING WIRING CONNECTIONS, CHECK THAT THE MOTOR ROTATES
IN DIRECTION OF ARROW (CLOCKWISE WHEN THE SHAFT IS VIEWED FROM THE
WIRING CONNECTION END). TO ALTER ROTATION, CHANGE ANY TWO POWER
LEADS AT MOTOR TERMINALS.
POWER CONNECTIONS AND WIRING MUST BE CARRIED OUT BY AN
AUTHORISED ELECTRICIAN.
NOTE: Three phase motors do not have capacitors tted in the capacitor
cover.

Never run pump dry. Running the pump with no water may damage the
mechanical seals, causing leakage and ooding. Dry running damage and
associated damage is not covered under warranty.
Failure to undertake regular maintenance may cause damage not covered
by warranty.
DANGER - Hazardous suction. Do not block water entry into ltration
system with any part of your body as the pressure can trap hair or body
parts, causing severe injury or death. Do not block suction. Turn off
pump immediately if someone becomes trapped.
Caution! Do not add chemicals directly to the pool skimmer. Adding undi-
luted chemicals may damage pump and lter and void warranty.
Small children using the pool or spa must ALWAYS have close adult su-
pervision.
Routine Maintenance tasks – to maximise the life of your pool equipment
& personal safety, use this checklist once a week. Turn pump off rst.

WARNING! Pump suction is hazardous and can trap and drown or disem-
bowel bathers. Do not block suction. Do not use or operate swimming
pools, spas or spa baths if a suction cover is broken, missing or loose.
Two suction covers and inlets must be provided into every pump to avoid
suction entrapment.
Power supply to this pump needs to be through an isolating transformer
on RCD, having a rated operating current not exceeding 30mA.
