user maintenance.
CAUTION: Some parts of this product can
become very hot and cause burns. Particular
attention has to be given where children and
vunerable people are present.
WARNING: This heater is not equipped with a
device to control the room temperature. Do not
use this heater in small rooms when they are
occupied by persons not capable of leaving the
room on their own, unless constant supervision
is provided.
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.
The heater must be wall mounted level ± 5º to
the horizontal.
Young children should be supervised to ensure
that they do not play with the appliance.
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,
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.
The supply cord should be regularly examined
for signs of damage and the appliance is not to
be used if the cord is damaged.
If the supply cord is damaged it must be replaced
by an assembly available from the manufacturer
or service agent.
Note: Provide sufcient slack to the cable to allow
for angular adjustment of the body.
The bulbs are extremely fragile and must be
handled with extreme care at all times. Always
handle the Halogen bulb without touching the
glass (by gripping the ceramic ends gently
but rmly) to maximise bulb life. If the bulb is
accidentally touched by bare ngers remove
the ngerprint with a soft cloth moistened with
methylated spirits.
IMPORTANT: The appliance is to be connected
to a socket outlet having and earth contact.
A double pole isolating switch with a minimum
separation of 3mm in each pole must be tted
to facilitate isolation.
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 tted
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 coefcient 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 (for Class I appliances).
Installation – Wall Mounting
Heaters are supplied with an integral wall bracket which
may be xed through the mounting holes to any suitable
structure.
Note: The wall bracket is tted to the appliance in the
packaging during transit. To remove the appliance from
the bracket remove both securing knobs.
The recommended xing height to the centre line of the
bracket is 2.0m from ground level - see Fig. 2. Mark the
hole positions and drill to suit. When the bracket is xed
in position, align the appliance as indicated in Fig. 2a,
and locate the appliance in the slots, rotate the heater as
shown in Fig. 2b and tighten the securing knobs fully.
The bracket allows the heater to be inclined at the
required angle. 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.
If the bulb is accidentally touched by bare fingers
remove the ngerprint with a soft cloth moistened with
methylated spirits.
