TECHNICAL AND INSTALLATION

INTRODUCTION

Intended users of these instructions:

- The specifying engineer.

- The installation engineer.

- The owner or user.

- The service engineer.

Warnings.

THE INSTALLER MUST READ AND UNDERSTAND THIS MANUAL BEFORE FITTING
THIS APPLIANCE.

IMPORTANT: Do not under any circumstances switch on the immersion heater
before the primary tank is filled.
Serious damage may result to the heater in addition to danger of personal injury
and damage to property if the heater is switched on when dry.

IMPORTANT: Always isolate electrical supplies and if necessary the water supply
before working on the unit.

IMPORTANT: Always fill and pressurise the secondary (domestic) tank first, filling
and pressurising the primary (heating) tank may result in crushing damage to the
domestic tank.

IMPORTANT: ACV recommends the use of a corrosion inhibitor in the primary
(heating) system. The warranty will be invalidated if upon inspection it is found
that a tank has failed due to corrosion caused by the lack of an inhibitor.

These instructions form an integral part of the equipment to which they refer and the user
must be provided with a copy.

The product must be installed and serviced by qualified engineers, in compliance with
current standards.

ACV cannot accept liability for any damage resulting from incorrect installation or from
the use of components or fittings not specified by ACV.

Any failure to follow the instructions regarding tests and test procedures may result in
personal injury.

ACV reserves the right to change the technical specifications and components of its
products without prior notice.

TECHNICAL AND INSTALLATION

1. OPERATION

A = Stainless steel internal tank
B = STW 22 carbon steel exterior tank
C = High density polyurethane foam insulation
D = Heating fluid entry point
E = Heating fluid outlet point
F = Sanitary hot water outlet
G = T & P relief valve connection
H = Cold water inlet
I = Control thermostat
K = Control thermostat pocket
L = Primary air vent
M = Co-polymer polypropylene top cover
N = Co-polymer polypropylene jacket

Principle:

ACV Tanks (tank in tank) comprise of two concentric water cylinders. Tank (A) is manufactured in
solid stainless steel and contains the domestic water for use at the sanitary hot water outlets. The
exterior tank (B) is manufactured from STW 22 carbon steel, this tank holds the primary heating
fluid which is circulated from the boiler, as the primary fluid passes between the two tanks the
heat is transferred to the domestic water.

Operation:

When the thermostat (I) calls for heat the primary pump is activated (or motorised valve is
opened) and primary fluid is circulated in the outer tank and transfers its heat to the domestic
water. Once the thermostat set temperature is achieved it will open and deactivate the primary
pump (or close the motorised valve). Initial heating from cold will take between 10 and 20 minutes
(depending on tank size and boiler output) – when operating temperature is achieved the
recovery becomes faster.
