Important Safety Advice

Because the Dimplex Outdoor Patio Heater contains no moving parts

little maintenance is required. Before undertaking any maintenance

work on the heater due attention must be paid to the following:

This heater is designed to be horizontally wall mounted only, it must

not be ceiling mounted.

Always ensure a safe mounting height, at or above a minimum height

of 1.8 metres from ground level, so that the heater can not be touched

when in operation.

This appliance is not intended for use by children or other persons

without assistance or supervision if their physical, sensory or mental

capabilities prevent them from using it safely. Children should be

supervised to ensure that they do not play with the appliance.

The heater must be wall mounted level ± 5º to the horizontal.

Do not locate the heater immediately above or below a fixed socket

outlet or connection box.

Always disconnect the heater from the electricity supply before

attempting to work on or near it.

Always ensure a safe means of access using an access tower or properly

supported ladder.

Do not cover the heater.

Keep combustible materials away from the heater.

Do not position patio furniture, sunshades, curtains, awnings and

other combustible materials too close to the heater.

Do not look into the heater for prolonged periods.

Do not use the heater if the elements are broken - as injury may occur.

Allow adequate time (minimum of 30 mins.) for the elements and body

casing to cool before attempting to work on the heater.

Do not allow the supply cord to sit or hang in front of the heater while

in use.

If the supply cord is damaged, the heater should not be used, it must

be replaced by an assembly available from the manufacturer or service

agent.

Note: Provide sufficient slack to the cable to allow for angular adjustment

of the body.

Always handle the Halogen bulb without touching the glass (by gripping

the ceramic ends gently but firmly) to maximise bulb life.

General

The OPH range of heaters are especially designed for use on Patio Areas. The

heaters provide warmth and comfort for recreational areas. The OPH13 uses

quartz elements which emit a warm glow of medium wave infra-red. The

OPH20 uses Halogen elements which produce a high proportion of their output

in the short-wave infra-red. This provides a high comfort factor – similar to the

natural energy from the sun.

The IPX4 rating means the appliance is suitably rated to be permanently

installed either internally or externally.

Electrical

The installation of this appliance should be carried out by a competent electrician

and be in accordance with the current IEE wiring regulations and any local or

insurance regulations.

The OPH13 & OPH20 are designed for use on a 230-240V AC single phase

supply. A double pole isolating switch with a minimum separation of 3mm in

each pole must be fitted to facilitate isolation. This switch must either be

positioned inside a building or have an IP rating against water ingress suitable

for external installation. The appliance must be supplied through a residual

current device (RCD) having a rated residual operating current not exceeding

30mA. The RCD for the OPH20 should be type 3 or C rated, with a tripping

coefficient of 7-10 times the rated current. Any other switching device should

be Tungsten lamp rated. The appliance must be connected to a socket-outlet

having an earthing contact.

Installation – Wall Mounting

Heaters are supplied with an integral wall bracket which may be fixed through

the mounting holes to any suitable structure. The bracket allows the heater to

be inclined at the required angle. The recommended fixing height to the centre

line of the bracket is 2.0m from ground level - see Fig. 2. The integral wall

fixing bracket may be removed by fully unscrewing to facilitate its fixing. The

siting of the heater(s) should be such as to allow an even and uninterrupted

distribution of radiation to the area(s) to be heated. Heaters are most effective

when the beam angle is inclined down at an angle of between 30º to 45º to the

vertical - see Fig. 2. When deciding upon the best location, consideration must

be given to the following requirements:

a. Avoid structures which might vibrate e.g. crane gantries. These could

adversely affect element life.

b. Comfort and safety could be compromised unless the heater is mounted at

or above 1.8m from ground level.

c. Allow a minimum of 500mm minimum clearance between the top of the

heater and any horizontal surface- see Fig.1.

Installation – Pole Mounting

The OPH range of patio heaters can be permanently mounted to parasols,

poles or other support structures. A mounting kit (OPHMK1) can be obtained

directly from Dimplex or any of its service agents. Refer to the instructions

supplied with this kit for further advice.

Cleaning and User Maintenance

WARNING: BEFORE UNDERTAKING CLEANING OR MAINTENANCE WORK

ON THE APPLIANCE, DISCONNECT THE ELECTRICITY SUPPLY.

Since the appliance contains no moving parts little maintenance is required

beyond cleaning and element replacement. It is however essential that the

heater is not operated with an accumulation of dust or dirt on the element, as

this can cause a build up of heat and eventual damage. For this reason the

heater must be inspected regularly, depending upon conditions and at least at

yearly intervals. Allow adequate time for the element and body casing to cool

before attempting to work on the heater - a minimum time of 30 minutes is

recommended.

Clean the lamp(s) and reflector using a mild detergent solution and soft cloth.

Do not use any abrasive or caustic cleaners. Dry with a soft cloth. Avoid

touching either the lamp sleeve or the aluminium reflector with bare fingers. If

they are accidentally touched, remove any fingerprints using a soft cloth

moistened with methylated spirits.
