The Leisure Time range of pool pumps are ideal for domestic swimming pool and
spa applications. They offer unique corrosion protection with double zinc coated
cast iron endshield mounted on a non-corrosive base. The Leisure Time pool
pumps have been designed to provide performance at a realistic cost.
IMPORTANT!
The operator must be provided with this owner’s manual. This must be read
before operation and followed during operation.
These instructions are a guide only. Users not familiar with pool equipment
should seek advice from suitably qualified persons with experience in pool

The fittings on these pool pumps are constructed ofABS. Some PVC jointing
compounds are incompatible withABS possibly causing failure to the product.
Check compound suitability prior to use.
All glued fittings and pipe work should be allowed to dry to atmosphere for 24
hours before closing installation. Failure to do so could cause injury or instal-
lation failure.
Barrel Unions are to be hand tightened ONLY, to prevent damage occurring
from over-tightening.
Pump Mounting should be:
INSTALLATION
1) Pump position must be: Solid - Level - Rigid - Vibration Free
2) Allow pump suction inlet height to be as close to water level as possible.
3) Allow for use of a piece of short, straight suction pipe into the suction port
of the pump (minimum length for 40mm diameter suction = 160mm; 50mm
diameter suction = 200mm) in order to minimise water turbulence entering
the pump.

4) Allow for control valves in suction and discharge piping. (Essential if pump
is mounted below water level).
5) Have adequate floor drainage to prevent pump being immersed in water due
to flooding.
6) Protect from excess moisture, vermin, dust and weather.
7) Allow access for servicing pump and piping.
8) To provide adequate ventilation keep rear of motor clear (100mm Min)
9) Do not use electrical extension cords/leads.

water before starting motor.

Do not block pump suction! To do so with body
may cause severe or fatal injury. Small children
using pool must ALWAYS have close adult
supervision!

OPERATION (Continued)
PrimingPump:
a) Inafloodedsuctionsystem(watersourcehigherthanpump),thepumpwill
fill itself with water when suction and discharge valves are opened. Water
will be at the top of the hair and lint pot lid.
b) If pump is not in a flooded suction system, unscrew and remove hair and
lint pot lid; fill pot (casing & bowl assembly) with water.
c) Clean,inspectandlubricate'O'Ring;reinstall‘O’ringontobowlassembly.
d) Replace lid onto bowl assembly; turn clockwise to tighten lid.
Tighten lid by hand only (no wrenches)!
Do not run pump dry or damage will occur and
may void warranty.
Start-up Procedure:
1) Release all air from filter and piping system: see filter owner's manual.
2) Turn pump “ON” at power point or controller.
3) Pump should prime now. Priming time will depend on vertical length of
suction lift and horizontal length of suction piping.
If pump does not prime within a few minutes, make sure that all valves are
open, suction pipe end is under water and that there are no leaks in suction
pipe.Ensure the skimmerbasket onpool isclean andfree ofdebris. Repeat

The only routine maintenance needed is inspection/cleaning of leaf basket. Debris or
trash that collects in basket will choke off water flow through the pump. Follow
instructions below to clean leaf basket:
1. Stop pump, disconnect from power, close gate valve in suction and discharge.
2. Unscrew lid (turn counter clockwise). If necessary, undo drain plug to reduce lid
vacuum. Do not hit the lid with a hammer or similar tool. If the lid is still too tight use
a lever such as a board or long screwdriver between lugs on lid.
3.Removeleafbasketandclean.Besureallholesinbasketareclear,flushbasketwith

(between ribs provided). If basket is replaced backwards the lid will not fit into bowl
assembly.
4. Inspect, check and lubricate lid 'O' Ring; reinstall onto bowl assembly.
5. Clean 'O' Ring groove on bowl assembly and replace lid. To help keep lid from
sticking, (tighten hand tight only no wrenches!).
