YCSH parking heater · Installation, operation and maintenance instructions

Intended use of the heater

The heater is designed to provide heating and maintain a comfortable temperature in the following vehicles and spaces:

• Vehicles: Cars; vans; caravans and motorhomes.
• Enclosed spaces: Cabins; garage; storage rooms and other similar environments.

Operating characteristics:

• Operates independently of the vehicle engine, using diesel fuel as the energy source.
• Requires a 12 V electrical connection capable of supplying an instantaneous consumption of at least 10 A.
• Includes automatic temperature regulation via a sensor integrated into the control display.

Note: This unit ensures efficient and autonomous heating for a wide variety of applications.

Rules for installation in the vehicle

1. Skydd mot värme och spill: skydda närliggande delar och förhindra eventuellt spill från att skada andra komponenter.
2. Avstånd och ventilation: håll tillräckligt avstånd och säkerställ tillräcklig ventilation i facket.
3. Skyddsmaterial: använd eldfasta/termiska skyddsmaterial vid behov.
4. Identifiering av utrustning: efter installationen, fäst en kopia av tillverkarens etikett på en synlig och tillgänglig plats i fordonet.

Regler för installation inuti fordonet

1. Användning av löstagbara anslutningar i avgas- och bränsleledningar är inte tillåten.
2. Avgas- och insugsrör ska fästas med de medföljande klämmorna och dras utåt.
3. Installationsytan måste vara helt plan (använd monteringsplatta om den inte är det).
4. På träytor: skär runt avgasröret och lämna 2–3 cm, eller skär av omkretsen så att den vilar på fordonets metallplåt.

Bränsletillförsel

• Via en "T"-anslutning eller pickuprör installerat i fordonets tank.
• I den bärbara versionen, tanken integrerad i värmaren kan användas.

• Det kommer inte att accepteras vid fordonsbesiktning i Spanien.
• Värmaren måste anslutas till fordonets tank med tillbehören som ingår i installationssatsen.

För användning av det medföljande T-stycket, den får endast användas i fordon där INGEN förpump finns i tanken. (Annars kommer diesel ut genom värmarens avgaser/intag när motorn startas.)

Beroende på typ av fordon, år, etc., den kan installeras på SUPPLY eller RETURN-linjen. I vissa fall kommer det att vara nödvändigt att använda en backventil för att förhindra förlust av fyllning i fordonets bränsleledning.

Det bästa sättet att göra detta är genom att installera pickupröret som medföljer enheten.
Vissa tankar har redan en avsedd plats eller urtagning för installation, och vissa fordon kommer till och med med en förinstallation för en extra värmare.

Bränsleledningen ska vara så kort som möjligt, och försök att inte överskrida det maximala avståndet för 5 m.

Det rekommenderas att installera pumpen nära bränsletanken mellan 0 och 1 m, eller så långt som pumpkabeln tillåter, se till att den längsta sektionen alltid är mellan pumpen och värmaren (max 4 m).

Avgassystem

⚠ Viktig varning:
Enheten är designad och kalibrerad för att fungera med originalavgasröret som levereras från fabriken. Det rekommenderas inte att ändra dess längd.

Om det är nödvändigt att lägga till en förlängning, den får inte överstiga 30 cm ytterligare, bibehålla samma diameter och egenskaper som originalröret. Felaktig modifiering kommer att påverka prestandan, orsaka kolansamling och leda till oregelbunden drift.

• Utloppet måste installeras så att ingen möjlighet att gaser kommer in i det inre undviks.

• Håll avgasutloppet borta från eventuella öppningar eller luftintag i kabinen.

Förbränningsluftintag

⚠ Viktig varning:
Förbränningsluftens intagsrör beräknas och kalibreras för denna enhet. Det är strängt förbjudet att förlänga den eller ändra dess diameter eller egenskaper. Den får endast förkortas om det behövs för installationen.

Any unauthorized modification may cause incomplete combustion due to lack of air, malfunction, carbon buildup and void the warranty.

• Air for the combustion chamber must not be taken from inside the vehicle.
• The intake must be installed/protected so it cannot become blocked.

Hot air intake

• It can be taken from inside (återcirkulation) or outside (in a place with clean air, not contaminated by exhaust fumes).
• If taken from outside: protect the duct with a grille and place the intake avoiding contamination from harmful gases.

Hot air outlet

The ducts must be installed securely. It is essential to ensure that the outlet cannot become blocked.
If using a boiler with hot air inlet together with the heater, it is recommended to install a Y to split the hot air flow so it does not all pass through the boiler.

Installation

Allowed mounting positions

• Recommended: normal position.
• Inclined: up to 30°, with the lower end towards the hot air outlet.
• Rotated: 90° to one side; fuel inlet and glow plug always upwards.

Outdoor installation

• Protection against splashes: sheltered from water, snow or dirt.
• Orientering: horizontal with exhaust facing down and inclination up to 30°; if rotated 90°, glow plug and fuel inlet always up as shown above.
• Gas evacuation: The exhaust pipe must be oriented so gases cannot re-enter the vehicle or affect sensitive components. A slight downward inclination or a 4 mm drainage hole at the lowest point is recommended to allow condensate to escape
• Avstånd: Always maintain adequate distance between the exhaust system and heat-sensitive components. Ensure it cannot burn electrical cables, brake hoses, fuel lines and other plastic components.
• Secure fastening: The heater must be firmly fixed using its original mounts to prevent damage from vibrations and deformation.
• Brackets and sealed boxes Use specific mounting brackets or sealed boxes for better protection against impacts and splashes of water or snow.

Changing the wiring harness position

If necessary, the harness connection can be moved to the opposite side:

• Remove the top cover.
• Remove the cable and slide it under the motor to the opposite end.
• Remove the rubber plug from the opposite end before placing the cable.
• The usable cable length will be considerably reduced.
• Place the rubber plug on the original end and reinstall the top cover.

Mounting and fixing the heater

To ensure a safe and stable installation of the heater, follow these guidelines:

Drilling:

Use the mounting plate/template included in the kit to make the necessary holes for:

• The exhaust.
• Förbränningsluftintag.
• Fuel connection.

Use of the mounting plate:

It is mandatory to use the mounting plate if the surface where the heater will be installed has ribs, bumps or irregularities.

The plate ensures the heater rests on a completely flat surface, preventing deformation and ensuring a stable installation.

Fixing and support surface:

• Under no circumstances should the heater be placed directly on bumps, objects, wiring, insulation or other components.

• Contact of the casing (aluminum or plastic) with external elements may cause deformation that blocks the motor and generates irreversible damage not covered by warranty.

Sealing:

• Correctly install the rubber seal provided to prevent gases from entering through the holes made.

Minimum clearance between walls and furniture

Recommended minimum 5 cm. If not possible:

• Aluminum casing: can be flush (barely heats up).
• Plastic casing: mandatory minimum 2 cm (makes disassembly/maintenance more difficult).

Hot air ducting

Install ducts securely. If no intake duct is installed, keep the grille; if ducts are installed, use an equivalent grille 2kw or 5kw depending on the case.

Do not take intake air right next to the hot air outlet; keep them as far apart as possible.
Avoid very sharp bends within the first 10 cm of the outlet, and avoid 90° elbows right at the heater outlet as this may cause overheating errors.

Exhaust pipe in the portable version

The portable heater includes two exhaust sections, each designed for a specific use:

• Short section: Must be used only outside the vehicle. Designed for use when the heater is placed on the ground, allowing it to be bent and direct exhaust gases to the side.
• Long section: Designed for fixed installations, with a double layer for greater robustness and better sealing. It can be cut and a silencer inserted at the desired position. In this case, the short section can be placed after the silencer, but never before.

Install the combustion intake so it does not draw in exhaust gases (as far away as possible; preferably opposite side).

Protect intake to prevent air/water/mud/snow from entering. Exhaust should be as straight as possible with downward inclination; if there is a “belly”, make a drainage hole.

Silencer preferably as shown; otherwise horizontal with slight downward slope. The final section after the silencer must point towards the ground.

Ideal inclination between 15º and 35º (can be vertical). The side with the electrical connector is the outlet and must be higher.

Control panel installation

The panel includes a temperature sensor: incorrect placement may distort readings.

• Do not install in front of airflow or on metal surfaces.
• Excessive handling heats the panel and temporarily distorts readings.
• If cutting/splicing to extend: do not reverse wires (damages display, no warranty).
• Extending more than 5/6 m is not recommended.

Battery power supply system recommendations

2.5 mm² cable is suitable up to 2 m from the battery. For longer distances or non-optimal lead/AGM/GEL batteries:

• Cut near the main connector.
• Splice in a larger section cable (4 mm² or 6 mm² depending on distance).

Caution: voltage below 11.8 V may cause failures (bad/discharged battery or voltage drop due to insufficient cable), poor combustion and soot.

Heater test after installation

1. Check that the fan spins freely (if blocked, it may damage the motor; not covered by warranty).
2. Check battery voltage ≥ 11.8 V (visible on screen).
3. Verify configuration: size (2 kW or 5 kW) and pump type (22 ml).
4. Prime fuel until it reaches the heater; avoid excessive priming (bärbar max 20 s).

Operation tests on first start

If over-primed, there will be white smoke for 5–10 min. Set maximum power (power mode 10). After ~15 min it should not emit smoke.

Then minimum power (1), wait for stabilization and observe exhaust: it should not emit black smoke.

If it emits black smoke in either test, contact technical service: garantias@ycsh.es

Heater startup phases

1. The fan starts spinning slightly.
2. The glow plug turns on (40–60 s).
3. The pump operates intermittently.
4. After 3–4 min, temperature increase becomes noticeable (not instant).

YCSH heater maintenance

Fixed unit

To ensure optimal operation, it is recommended to run the unit for approximately 15 minuter every 30–40 days at maximum power. This helps renew the fuel accumulated in the pump and lines, preventing degradation.

Portable unit

1. Recommended option: Completely empty the fuel tank and run the heater until it stops with fel 8.
2. Alternativ (if installation does not allow full draining): Refill the tank with small amounts of fuel and consume them proportionally. This helps renew the fuel without leaving buildup in the tank.

Consequences of not performing maintenance

Over time, diesel tends to degrade due to the presence of biodiesel and moisture, causing:

✅ A color change to a more intense yellow.
✅ Formation of sticky sediments at the bottom of the tank.
✅ Possible appearance of diesel bacteria.

These residues can adhere to the pump piston, hindering its movement and causing:

❌ Poor operation.
❌ Total pump blockage.
❌ Costly and complex repairs. (depending on the unit and installation)

Performing this periodic maintenance is key to extending the unit’s lifespan and avoiding failures not covered by warranty.
