1. INTRODUCTION

• Read this instruction manual before proceeding.
• Important documents in addition to this instruction manual are the order confirmation, the specification
sheet and drawings.

1.1 Warranty and liability

The "General Conditions of Sale of WEKA Boxcooler BV" are applicable. Also refer to the order confirmation
for possible additions.
Please make sure to fill in the supplied "Boxcooler Warranty Registration" form and sent the registration to WEKA
for review and guarantee purposes.

1.2 Receipt of goods

• Upon receipt of goods, please report any damage or discrepancy to WEKA Boxcoolers BV.
• Compare the data on the identification plate, order confirmation and on the drawing.

1.3 Verifying correct installation of Boxcoolers

WEKA Boxcoolers must be mounted galvanically isolated from the ship's hull. This is to safeguard the lifetime of
the Boxcoolers, to avoid marine growth on the Boxcoolers and to avoid corrosion. The WEKA Guard and WEKA
Protector are the devices which control and protect the Boxcoolers and the ship from these phenomena, provided
the Boxcoolers are correctly installed.
A few things also mentioned in the "Installation Manual for WEKA Boxcoolers" are highlighted:
1. Make sure the mounting of the Boxcooler is complete – including the bonnet on top of the cooler.
2. The top-plate of the sea-chest (tank top) shall be cleaned from water and obstructing materials.
3. Check the galvanic isolation of the Boxcooler using relevant procedures as below:
Ship is in dry-dock – Boxcooler is not submerged and WEKA Guard is not connected yet
• Measure the resistance Ω (Ohm) between the cooler and the ship's structure. The resistance must not
be less than 500 Ω (Ohm).
Ship is afloat – Boxcooler is submerged and WEKA Guard is connected
• Measure the resistance between the tube-sheet and a bare piece of the top-plate of the sea-chest.
The potential difference should be approximately 200-350 mV.
Please consult WEKA in case any questions should arise.
