PREPARATION
Handling
The purchaser is responsible for off-loading. Heaters
are individually packed and two/three persons can
usually handle the heaviest heater. If a significant
quantity is delivered, they may be palletised and
shrink-wrapped, so a fork-lift or similar will be
required for lifting. Heater must not be dropped or
suffer impact in any circumstances.
Storage
Heaters should be stored in clean, dry conditions.
Any packaging should not be removed until the
heater is required for installation and should only be
removed if damage is suspected at delivery
.
Fixing & Connections
Make proper provision for fixings. The structure to
which heaters are to be fixed must be fit for purpose
and capable of accepting plugs and screws, anchor
bolts or drop rods. Floor models require a level base.
Floor and wall models require a sound flat wall
surface. Heater casings are supplied with knockouts
for pipework and conduit entry.
Piping and electrical conduit should, as far as
possible, have been completed and any wall
apertures for loose grilles and ductwork should be
fully prepared.
WARNING:
Some internal components may have sharp edges. Protective gloves should be worn.
INSTALLATION
General
1. Check the identity of the heater marked on
the outside of the carton. The carton can be
saved to protect the heater from damage by
other trades after installation.
2. Unlock and remove the access panel with the
key provided with the heater. On ceiling
models, safety screws retain the access panel
in a hinged position.
3. Re-check the identity of the heater, from the
serial number on the nameplate.

The inner cover, fans/motors pipework cover
plate, filter and grilles can all be removed to
provide better access when making pipework
connections and to allow easier lifting of wall
and ceiling models. (See Diagram 6)
5. Disengage the line connector to disconnect
the wiring harness to the fan platform. On
ceiling models, remove the platform retaining
brackets before removing the platform.
6. Remove the casing knockouts,to suit pipework
