INSTALLATIONS INSTRUCTIONS — PLEASE READ CAREFULLY

GENERAL

The spa heater is the rst of a new generation of heaters that have been totally
redesigned to incorporate all the latest concepts in safe water heating. The heater
is reliable, easy to install, simple to operate and easy to maintain. It includes all its
own control and safety devices. It is designed to look after itself.

All the control system of the spa pack has to do is turn on the pump. The heater
detects the water pressure change and operates accordingly.

INSTALLATION

Before planning any installation please note the following:

1. The heater power supply is not controlled by the spa control box.

2. Heaters up to 2.4kW are normally used for portable spa pools and thus the
heater is provided with a 3 pin socket to permit the connection of a suitable
control box directly to the heater without additional wiring.

3. It is strongly recommended that the supply of all spa installations be protected
by an EARTH LEAKAGE CIRCUIT BREAKER [ELCB] [RCD] preferably tted at
the switchboard.

4. All installations must comply with AS3000 and the special requirements of
section 6 and any additional requirements of your local supply authority bylaws.

PHYSICAL LOCATION

The heater should be located in the spa system as follows:

1. On the pressure side of the pump.

2. Before the lter in the return line.

3. Where it is accessible for maintenance with enough clear room to remove
control head from heater body.

4. In a vertical position, or if horizontal, so that the side port faces down.

5. It is recommended that the Classic Spa Heater water inlet is set to the higher
port. If for installation reasons this is not possible, the lower port can be used for
water inlet as the Classic Spa Heater inlet / outlet ports can be interchanged.

6. Level — denitely not plumbed at an angle.

7. Protected from rain, water splashes, hosing etc.

8. In an ambient temperature not exceeding 55°C.

Where the heater is being installed in a position exposed to the weather,
splashing and the like, it must be protected by an additional enclosure
having a degree of protection to IP24-AS1939.

WIRING

ALL FIXED ELECTRICAL WIRING MUST BE COMPLETED BY A SUITABLY
QUALIFIED PERSON.

1. Check the kilowatt rating of the heater. Ensure the correct size cable is being
used.

2. The cable entry point is via one of three knockouts provided on the underside of
the heater head. Use the correct size grommets and conduits when installing.

3. Check that wiring to terminal blocks is secured rmly and to the correct
terminals.

PLUMBING

1. The heater body may be plumbed so the water ow can be in either direction.

The head of the heater may be turned to any of the four keyed directions (90°) to

give best access to the thermostat control.

2. When installing the heater head the ‘O’ ring must be carefully

located on the element carrier and NOT in the body. When tting

head make sure the ‘O’ ring doesn’t become dislodged and fall
into the body. To assist assembly it is recommended that a light
lubricant be used on the inside of the body barrel to help the
components to slide together easily. REFER FIG.2 & 3.

3. When connecting pipework to heater make sure the ‘O’ rings are properly seated
in the mac union tting. NB. Hand tighten only. Using tools will distort the ttings.

4. Make sure the heater is mounted on its stand or secured rmly so that vibration
is minimised.

5. It is recommended that the pipework has shut off valves so the heater head can
be removed for service without loss of water or downtime due to reheating.
