Installation and operating instructions

General Instructions Read these instructions carefully before installation and use. Keep this manual for future reference.The product may only be used as set out in the assembly and operating instructions. The guarantee is only valid if the product is used in the manner intended and in accordance with the instructions. Application area SWL is a fan heater with low sound level intended for water heating. SWL is suitable for industrial premises where fan heaters are traditionally used, but also in environments such as shops and assembly halls. The fan heater can be mounted on the wall or the ceiling. Protection class: IP44.

SWL

20

GB

The unit consists of the following:Corrosion-proof, hot rolled galvanized and powder coated casing. Colour code: RAL9016,NCS 0500. Top/bottom lids open, for maintenance.

Fully enclosed single-phase 230V, 50Hz, intergrated motor with an axial fan. Protection class IP44. Maximum surrounding temperature: +40 °C.

Heating coil with aluminium fins (fin distance 2 mm) and copper tubes. Smooth pipe connections for soldering or clamping ring coupling. In standard designs, SWL is intended for hot water up +150 °C and 10 bar.

All models are delivered with individually adjustable louvres for controlling the air current in one direction. Louvres of anodized aluminium.

MountingThe unit is delivered with casing, fan, heating coil and air director as standard. Mounting brackets are orded separately.

Can be mounted on the wall for horisontal air distribution or on the ceiling for vertical

air distribution. By turning the fan heater, pipe connections are possible on both sides.

Mounting without accessoriesMeasure and mark the drilling holes on the wall or on the celing. Use a suitable screwing device to fit the brackets. Use the included set of screws to fit the brackets on to the unit.

Mounting with filter section SWFWhen the filter section is used with the unit and mounted on to the wall, use the return air intake SWD. The return air intake is mounted together with the SWL unit with screws or guides. The return air intake is mounted on to the wall with a suitable screwing device.

Check the connections between the units, in case of air leakage use a suitable strip seal. All casings of the accessories are laquered on delivery.

Mounting of the basic filter SWSFTThe unit can be provided with a basic filter to protect the heating coil (not included on delivery). The top/bottom lid is opened, and the filter is slid down behind the coil in tracks for this purpose. The filter can be reached for installation and cleaning/maintenance from both top or bottom of the unit.

SWL with the extra air director SWLRThe extra air director is mounted to the unit by hooking it onto the existing air director.

Ceiling mountingThe unit and the filter section are mounted onto each other on the floor and lifted up as one unit to be mounted on the ceiling. The units should be mounted together with screws or guides.

Connection of heating coilThe installation should be carried out by a certified installer. By turning the fan heater, pipe connections are possible on both sides. Heating coil with copper pipes. Smooth pipe connections for soldering or compression

fittings. For correct inlet and outlet connection of the heating coil, see dimension sketch.Note! Be careful while connecting the pipes to prevent pipe damage and water leakage. The heating coil must not be connected to a mains pressure water system or an open water system.

Prior to use, the pipe system should be ventilated. The air valve should be connected on a high point in the pipe system. Air and draining valves are not included in the heating coil.

Electrical installationThe electrical installation should be carried out by a qualified electrician in conformity with prevailing regulations. The appliance should be preceded by an triple-pole switch with at least 3 mm breaking gap.The fan motor is connected to a detached terminal box, which is mounted on a wall next to the unit.

When a filter section is used, holes must be made in the casing for connection cables. The motor has a built-in thermal safety cut-out to protect against overheating. This will reset automatically once the motor has cooled. Cable-glands used must guarantee the protection class requirements.

After the electrical installation of the motor, check the rotation of the fan. Seen from the inlet side, the impellers should be rotating anti-clockwise.

Low or high speed can be selected with or without control, see wiring diagrams.

Maintenance To ensure performance and reliabilty of the unit, inspection and cleaning should be carried out reguarly. Inspection should be carried out at least twice a year. Clean the unit when needed. During inspection the power supply must always be disconnected.

Cleaning the fanCleaning intervals of the fan depends on filter (if any) and air quality. When a filter section with a deep-pleated bag filter is used and the indoor air is of normal quality, the unit is generally cleaned once a year. If the impellers

are not cleaned properly, vibrations/noise can occur and severly damage the bearings. If the vibration/noise remains after cleaning, please contact a certified technician.

The unit, the filter section and the heating coil can be vacuumed from dust.

When there are no accessories on the inlet side, inspection of the fan can be made from the outside of the unit. When the filter section is used, inspection can be carried out by the inspection door on the side of the filter section.

FilterIf used, the basic filter should be cleaned when necessary and checked at least 4 times a year. To clean the filter, open top or bottom lid by loosening a pair of screws underneath the lid and vaccum.The filter in the filter section is a deep-pleated bag filter, type EU3 (G85). It should be replaced when the recommended pressure drop is increasing 75 Pa. Check the pressure drop at least 4 times a year.Pressure drop for deep-pleated bagfilter replacement: 75 Pa.
