Incorrectly installed or tested equipment may fail, causing severe injury
or property damage.

Read the following instructions in this owner’s manual
when installing and operating equipment. Have a trained
pool professional perform all pressure tests.

1. Do not connect system to high pressure or mains
water system.

2. Use equipment only in a swimming pool or spa pool
installation.

3. Install pump with at least 2 hydraulically balanced
main drains equipped with correctly installed, screw ­fastened, antientrapment certified covers according
to local regulations.

4. Trapped air in system can cause explosion.
Ensure all air is out of the system before operating or
testing equipment.

Silentflo is electrically connected. Ensure that it is isolated
from electrical supply during installation and any subsequent
service work.

The pump should be installed and serviced by a suitably
qualified person in order to avoid hazard.

These instructions are a guide only. Should you the installer or
owner of the product be unfamiliar with the correct installation
or operation of this product you should contact a suitably
qualified person for advice.

Freezing conditions will damage the unit, as water expands as
it freezes. Ensure that Silentflo is located so that it is not prone
to freezing, or ensure that the product is disconnected and
dried of water during cold conditions.

Installation

(Have a trained pool professional perform all pressure tests).
Before pressure testing, make the following safety checks:

1. Check all clamps, bolts, lids, and system accessories prior to testing.

2. Release all air in system before testing.

3. Tighten trap lid to 4.1kg-m torque for testing.

4. Water pressure for test must be less than 170kPa (25 PSI)

5. Water tempertaure for test must be less than 38°C

6. Limit test to 24 hours. After test, visually check system to be sure it is ready
for operation. Remove trap lid and retighten hand tight only.

Fire and burn hazard. Modern motors run at high temperatures. To reduce
risk of fire, do not allow leaves, debris, or foreign matter to collect around the
pump motor. To avoid burns when handling the motor, let it cool for at least
20 minutes before trying to work on it. A thermal overload switch protects the
motor from heat damage during operation.

Only qualifi ed, licensed personnel should install pump. The electrical
installation shall be in accordance with the national wiring rules (AS/NZS 3000)
for class I, IP55 rated products. Refer to page 10 for Electrical Installation.
