Davey SPAPOWER CLASSIC HEATER - Manual (Page 2)

INSTALLATIONS INSTRUCTIONS — PLEASE READ CAREFULLY
GENERAL
The spa heater is the first 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 fitted 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 filter 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 — definitely 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.
