Always observe the Safety Notes 
designated by the Warning symbol:

Ì

Listed throughout this manual.  

 

Ì

!

 Leakage from a DuoSafety plate is always 

the early warning for the user to act. 

(See page

 

12)

 

 

Ì

!

 APV Paraweld PHE - Care must be 

exercised in connecting the fluids correctly. 

(See 

page 13)

 

 

Ì

!

 APV Paraweld PHE is not suitable for 

hygienic duties. 

(See page 13)

  

 

Ì

!

 Some general safety precautions must be 

followed in order to avoid personal injury or 

equipment damage. 

(See page 14)

 

 

Ì

!

 Lifting equipment must be in good condition 

and should always be used in full compliance 

with the specifications and limitations given for 

the equipment. 

(See page 17)

 

 

Ì

!

 Always maintain the minimum angle 

between the lifting wires in order not to exceed 

the allowable wire tension. The angle should 

not exceed 120

°

 at any time. 

(See page 17)

 

 

Ì

!

 Always observe proper procedures for lifting 

and/or moving equipment and qualified 

personnel for the lifting and moving. 

(See page 

17)

 

 

Ì

!

 Ensure sufficient space around the plate 

heat exchanger. 

(See page 18)

 

 

Ì

!

 Ozone-producing equipment, salt air and 

other corrosive atmospheres must be avoided 

at all times. 

(See page 19)

 

 

Ì

!

 Start-up of the plate heat exchanger. 

(See 

page 20)

 

 

Ì

!

 Exceeding the design temperatures and 

pressures can be harmful. 

(See page 20)

 

 

Ì

!

 Sudden changes in the operating pressures 

and temperatures should be avoided. 

(See page 

21)

 

 

Ì

!

 Never open the APV plate heat exchanger 

until the unit has cooled below 40

°

C (105

°

F). 

(See page 23)

 

 

Ì

!

 Never open an APV heat exchanger, which 

is under pressure from any source. 

(See page 

23)

 

 

Ì

!

 Never open an APV plate heat exchanger 

with piping connected to the follower or 

connector grids. 

(See page 23)

 

 

Ì

Bolts must not be slackened or tightened 

indiscriminately. 

(See page 23)

 

 

Ì

For large units, block the follower into 

position, for example by tying it to the end 

support, to provide extra safety against 

accidental rolling of the follower during 

maintenance. 

(See page 23)

 

 

Ì

!

 Always wear protective gloves when 

handling plates. 

(See page 23)

 

 

Ì

!

 Cleaning agents must not be aggressive or 

corrosive to the plates or the gaskets. If in 

doubt, contact the cleaning agent supplier. 

(See 

page 25)

 

 

Ì

!

 Do not use chlorine-containing agents such 

as hydrochloric acid (HCI). 

(See page 26)

 

 

Ì

!

 Excess Nitric acid can seriously damage 

NBR and other types of rubber gaskets. 

(See 

page 26)

 

 

Ì

!

 Do not permanently bend or scratch the 

plates or damage the gaskets during the 

installation. Some plates must be carefully bent 

to install them. 

(See page 29)

 

 

Ì

!

 Always tighten to full plate to plate contact, 

demonstrated by sufficient force and within the 

dimensions permitted. On the nameplate or the 

assembly drawing, you will find the minimum 

and maximum compressed dimension of the 

plate pack. 

(See page 31)

 

 

Ì

!

 Insufficient clamping force can cause 

leaking. 

(See page 32)

 

 

Ì

!

 For best rigidity of plate pack, tighten used 

plates to the same dimension again. 

(See page 

32)

 

 

Ì

!

 Never over tighten without written consent 

from APV as this can damage the flow plates. 

(See page 32)
