14 Loction ADVISES FOR INSTALLATION The POWERCIAT pckged units LX - LXC nd LXH re designed for outdoor instlltion. A free spce of 2 meters round the unit is necessry for good ir circultion nd mintennce. Choose the loction in order to respect environment (Acoustic level, etc,...) The sound level prolems must e nlysed in detil So, efore instlltion of the unit, study the est position, if necessry with sound technicin. If necessry, instll the unit on nt-ivirtion mounts nd equip the hydrulic pipes with flexile connectors (recommended equipments) POWERCIAT LX Hydrulic connections The hydrulic connections must e mde following good engineering prctice Pln ll the necessry ccessories for n hydrulic circuit : - Expnsion vessel - Drins t low points - Shut off vlves - Air vent t high points, etc. - Mke sure tht the instlltion wter contents is sufficient - Pln, if required, uffer tnk Electricl connections All the indictions concerning electricl connections re mentioned on the wiring digrm delivered with the unit (they must e respected). These connections must e mde following good engineering prctice nd in ccordnce to the norm in force. Leve the control uxiliry circuit under voltge to llow opertion of the crnkcse heter nd the ntifreeze heter (option) The customer electricl supply line must e fitted with circuit reker protection (to e supplied y the customer) Commissioning In ccordnce with our commissioning nd mintennce rochure Mintennce In ccordnce with our mintennce rochure Tke out mintennce contrct POWERCIAT LX - LXH - LXC Antifreeze protection If there is risk of freezing : - either supply evportor ntifreeze protection option (LX model) or evportor ntifreeze protection + hydrulic equipment option (LXH - LXC models) if instlltion runs with pure wter - or protect the instlltion with glycol concentrtion c - or drin the instlltion NOTE : With the ntifreeze protection, the unit is not protected ginst freezing nymore if there is n electricl supply filure
